css calc and min-height can not team up properly - css

i'm building a layout that has dynamic height (as most people do). i've been searching for a while but have not found similar case with mine.
so here it is, my simplified code:
html:
<div id="body"><div id="content">
content
</div>
</div>
<div id="footer">
abc
</div>
css:
#footer{
position: absolute;
bottom: 0;
width: 100%;
background: #ddd;
}
#body{
padding: 60px 50px 70px 50px;
position: relative;
min-height: calc(100% - 130px);
}
#content{
font-family: verdana;
margin-left: 200px;
border-left: 5px solid #ddd;
padding: 0 0 0 10px;
min-height: 100%;
min-width: 500px;
}
body{
margin:0;
overflow-y:scroll;
height:100%;
position:relative;
}
html{
height:100%;
}
the problem is when i use that code, the content height is not calculated properly and the result look like this fiddle while what i'm trying to do is when the content is short, it should look like this and when the content is long, it should look like this.
if i change the min-height to height, when the content is short, i get what i wanted, but when the content is long, i get this annoying layout
it seems calc cannot read the height attribute when it is not specified (using min-height), but if the height is specified, then i can't get dynamic height, is there any other solution to achieve this?
PS:
what i'm trying to do is to make the border of #content stretches according to its content with minimum height of a page height
note:
another strange fact is, actually my current code is working on latest chrome and IE, but have this problem on latest firefox and opera. i was trying to reproduce the problem using jsfiddle, and to my awe, all of the browsers have the same issue, i have included all the related html and css (copy the generated html and css) to jsfiddle only to find that my code is not working at all, i'm very confused

Why not use flex boxes? It sounds like you want a sticky footer - that is, the footer is at the bottom of the viewport when the content is not very high, but it is at the bottom of the content when the content exceeds the viewport height. This is very similar to the holy grail design. Here is an HTML5+CSS3 solution that does not use JavaScript:
* {
/* personal preference */
margin: 0;
padding: 0;
}
html {
/* make sure we use up the whole viewport */
width: 100%;
height: 100%;
/* for debugging, a red background lets us see any seams */
background-color: red;
}
body {
/* make the body a vertical flex container */
/* https://css-tricks.com/snippets/css/a-guide-to-flexbox/ */
display: flex;
flex-direction: column;
/* make sure we use the full width but allow for more height */
width: 100%;
min-height: 100%; /* this helps with the sticky footer */
}
main {
/* Allow the content to grow but not shrink */
flex-grow: 1;
flex-shrink 0;
/* for debugging, a blue background lets us see the content */
background-color: skyblue;
}
footer {
/* do not allow the footer to shrink */
flex-shrink: 0;
/* for debugging, a gray background lets us see the footer */
background-color: gray;
}
<main>
<p>This is the content. Resize the viewport vertically to see how the footer behaves.</p>
<p>This is the content.</p>
<p>This is the content.</p>
<p>This is the content.</p>
<p>This is the content.</p>
<p>This is the content.</p>
<p>This is the content.</p>
<p>This is the content.</p>
<p>This is the content.</p>
<p>This is the content.</p>
</main>
<footer>
<p>This is the footer. Resize the viewport horizontally to see how the height behaves when text wraps.</p>
<p>This is the footer.</p>
</footer>
If you don't want to copy the code into a fiddle yourself, I've done that for you. You may need to use some vendor prefixes if you want to support older browsers - flex boxes are relatively new as of the writing of this post.

Per our conv, you're after the ability to set the min-height so it fills the viewport with room for the footer, but as the content grows, the content div should too - pushing the footer down.
* { box-sizing: border-box }
html,body { height: 100%; padding: 0; margin: 0 }
#content { min-height: 90%; outline: 1px solid blue }
#footer { background: gray; height: 10%; }
It just takes setting the min-height using percentages. I'm using the border-box box sizing mode which is easier to work with but not required, in case you care about older IE

How to make an image to fill its container which has height in percentage? [duplicate]

I am working on a web application where I want the content to fill the height of the entire screen.
The page has a header, which contains a logo, and account information. This could be an arbitrary height. I want the content div to fill the rest of the page to the bottom.
I have a header div and a content div. At the moment I am using a table for the layout like so:
CSS and HTML
#page {
height: 100%; width: 100%
}
#tdcontent {
height: 100%;
}
#content {
overflow: auto; /* or overflow: hidden; */
}
<table id="page">
<tr>
<td id="tdheader">
<div id="header">...</div>
</td>
</tr>
<tr>
<td id="tdcontent">
<div id="content">...</div>
</td>
</tr>
</table>
The entire height of the page is filled, and no scrolling is required.
For anything inside the content div, setting top: 0; will put it right underneath the header. Sometimes the content will be a real table, with its height set to 100%. Putting header inside content will not allow this to work.
Is there a way to achieve the same effect without using the table?
Update:
Elements inside the content div will have heights set to percentages as well. So something at 100% inside the div will fill it to the bottom. As will two elements at 50%.
Update 2:
For instance, if the header takes up 20% of the screen's height, a table specified at 50% inside #content would take up 40% of the screen space. So far, wrapping the entire thing in a table is the only thing that works.
2015 update: the flexbox approach
There are two other answers briefly mentioning flexbox; however, that was more than two years ago, and they don't provide any examples. The specification for flexbox has definitely settled now.
Note: Though CSS Flexible Boxes Layout specification is at the Candidate Recommendation stage, not all browsers have implemented it. WebKit implementation must be prefixed with -webkit-; Internet Explorer implements an old version of the spec, prefixed with -ms-; Opera 12.10 implements the latest version of the spec, unprefixed. See the compatibility table on each property for an up-to-date compatibility status.
(taken from https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes)
All major browsers and IE11+ support Flexbox. For IE 10 or older, you can use the FlexieJS shim.
To check current support you can also see here:
http://caniuse.com/#feat=flexbox
Working example
With flexbox you can easily switch between any of your rows or columns either having fixed dimensions, content-sized dimensions or remaining-space dimensions. In my example I have set the header to snap to its content (as per the OPs question), I've added a footer to show how to add a fixed-height region and then set the content area to fill up the remaining space.
html,
body {
height: 100%;
margin: 0;
}
.box {
display: flex;
flex-flow: column;
height: 100%;
}
.box .row {
border: 1px dotted grey;
}
.box .row.header {
flex: 0 1 auto;
/* The above is shorthand for:
flex-grow: 0,
flex-shrink: 1,
flex-basis: auto
*/
}
.box .row.content {
flex: 1 1 auto;
}
.box .row.footer {
flex: 0 1 40px;
}
<!-- Obviously, you could use HTML5 tags like `header`, `footer` and `section` -->
<div class="box">
<div class="row header">
<p><b>header</b>
<br />
<br />(sized to content)</p>
</div>
<div class="row content">
<p>
<b>content</b>
(fills remaining space)
</p>
</div>
<div class="row footer">
<p><b>footer</b> (fixed height)</p>
</div>
</div>
In the CSS above, the flex property shorthands the flex-grow, flex-shrink, and flex-basis properties to establish the flexibility of the flex items. Mozilla has a good introduction to the flexible boxes model.
There really isn't a sound, cross-browser way to do this in CSS. Assuming your layout has complexities, you need to use JavaScript to set the element's height. The essence of what you need to do is:
Element Height = Viewport height - element.offset.top - desired bottom margin
Once you can get this value and set the element's height, you need to attach event handlers to both the window onload and onresize so that you can fire your resize function.
Also, assuming your content could be larger than the viewport, you will need to set overflow-y to scroll.
The original post is more than 3 years ago. I guess many people who come to this post like me are looking for an app-like layout solution, say a somehow fixed header, footer, and full height content taking up the rest screen. If so, this post may help, it works on IE7+, etc.
http://blog.stevensanderson.com/2011/10/05/full-height-app-layouts-a-css-trick-to-make-it-easier/
And here are some snippets from that post:
#media screen {
/* start of screen rules. */
/* Generic pane rules */
body { margin: 0 }
.row, .col { overflow: hidden; position: absolute; }
.row { left: 0; right: 0; }
.col { top: 0; bottom: 0; }
.scroll-x { overflow-x: auto; }
.scroll-y { overflow-y: auto; }
.header.row { height: 75px; top: 0; }
.body.row { top: 75px; bottom: 50px; }
.footer.row { height: 50px; bottom: 0; }
/* end of screen rules. */
}
<div class="header row" style="background:yellow;">
<h2>My header</h2>
</div>
<div class="body row scroll-y" style="background:lightblue;">
<p>The body</p>
</div>
<div class="footer row" style="background:#e9e9e9;">
My footer
</div>
Instead of using tables in the markup, you could use CSS tables.
Markup
<body>
<div>hello </div>
<div>there</div>
</body>
(Relevant) CSS
body
{
display:table;
width:100%;
}
div
{
display:table-row;
}
div+ div
{
height:100%;
}
FIDDLE1 and FIDDLE2
Some advantages of this method are:
1) Less markup
2) Markup is more semantic than tables, because this is not tabular data.
3) Browser support is very good: IE8+, All modern browsers and mobile devices (caniuse)
Just for completeness, here are the equivalent Html elements to css properties for the The CSS table model
table { display: table }
tr { display: table-row }
thead { display: table-header-group }
tbody { display: table-row-group }
tfoot { display: table-footer-group }
col { display: table-column }
colgroup { display: table-column-group }
td, th { display: table-cell }
caption { display: table-caption }
CSS only Approach (If height is known/fixed)
When you want the middle element to span across entire page vertically, you can use calc() which is introduced in CSS3.
Assuming we have a fixed height header and footer elements and we want the section tag to take entire available vertical height...
Demo
Assumed markup and your CSS should be
html,
body {
height: 100%;
}
header {
height: 100px;
background: grey;
}
section {
height: calc(100% - (100px + 150px));
/* Adding 100px of header and 150px of footer */
background: tomato;
}
footer {
height: 150px;
background-color: blue;
}
<header>100px</header>
<section>Expand me for remaining space</section>
<footer>150px</footer>
So here, what am doing is, adding up the height of elements and than deducting from 100% using calc() function.
Just make sure that you use height: 100%; for the parent elements.
A simple solution, using flexbox:
html,
body {
height: 100%;
}
body {
display: flex;
flex-direction: column;
}
.content {
flex-grow: 1;
}
<body>
<div>header</div>
<div class="content"></div>
</body>
Codepen sample
An alternate solution, with a div centered within the content div
Used:
height: calc(100vh - 110px);
code:
.header { height: 60px; top: 0; background-color: green}
.body {
height: calc(100vh - 110px); /*50+60*/
background-color: gray;
}
.footer { height: 50px; bottom: 0; }
<div class="header">
<h2>My header</h2>
</div>
<div class="body">
<p>The body</p>
</div>
<div class="footer">
My footer
</div>
How about you simply use vh which stands for view height in CSS...
Look at the code snippet I created for you below and run it:
body {
padding: 0;
margin: 0;
}
.full-height {
width: 100px;
height: 100vh;
background: red;
}
<div class="full-height">
</div>
Also, look at the image below which I created for you:
None of the solutions posted work when you need the bottom div to scroll when the content is too tall. Here's a solution that works in that case:
.table {
display: table;
}
.table-row {
display: table-row;
}
.table-cell {
display: table-cell;
}
.container {
width: 400px;
height: 300px;
}
.header {
background: cyan;
}
.body {
background: yellow;
height: 100%;
}
.body-content-outer-wrapper {
height: 100%;
}
.body-content-inner-wrapper {
height: 100%;
position: relative;
overflow: auto;
}
.body-content {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
<div class="table container">
<div class="table-row header">
<div>This is the header whose height is unknown</div>
<div>This is the header whose height is unknown</div>
<div>This is the header whose height is unknown</div>
</div>
<div class="table-row body">
<div class="table-cell body-content-outer-wrapper">
<div class="body-content-inner-wrapper">
<div class="body-content">
<div>This is the scrollable content whose height is unknown</div>
<div>This is the scrollable content whose height is unknown</div>
<div>This is the scrollable content whose height is unknown</div>
<div>This is the scrollable content whose height is unknown</div>

Original source: Filling the Remaining Height of a Container While Handling Overflow in CSS
JSFiddle live preview
CSS3 Simple Way
height: calc(100% - 10px); // 10px is height of your first div...
all major browsers these days support it, so go ahead if you don't have requirement to support vintage browsers.
It could be done purely by CSS using vh:
#page {
display:block;
width:100%;
height:95vh !important;
overflow:hidden;
}
#tdcontent {
float:left;
width:100%;
display:block;
}
#content {
float:left;
width:100%;
height:100%;
display:block;
overflow:scroll;
}
and the HTML
<div id="page">
<div id="tdcontent"></div>
<div id="content"></div>
</div>
I checked it, It works in all major browsers: Chrome, IE, and FireFox
Disclaimer: The accepted answer gives the idea of the solution, but I'm finding it a bit bloated with an unnecessary wrapper and css rules. Below is a solution with very few css rules.
HTML 5
<body>
<header>Header with an arbitrary height</header>
<main>
This container will grow so as to take the remaining height
</main>
</body>
CSS
body {
display: flex;
flex-direction: column;
min-height: 100vh; /* body takes whole viewport's height */
}
main {
flex: 1; /* this will make the container take the free space */
}
Solution above uses viewport units and flexbox, and is therefore IE10+, providing you use the old syntax for IE10.

I've been searching for an answer for this as well. If you are fortunate enough to be able to target IE8 and up, you can use display:table and related values to get the rendering rules of tables with block-level elements including div.
If you are even luckier and your users are using top-tier browsers (for example, if this is an intranet app on computers you control, like my latest project is), you can use the new Flexible Box Layout in CSS3!
What worked for me (with a div within another div and I assume in all other circumstances) is to set the bottom padding to 100%. That is, add this to your css / stylesheet:
padding-bottom: 100%;
In Bootstrap:
CSS Styles:
html, body {
height: 100%;
}
1) Just fill the height of the remaining screen space:
<body class="d-flex flex-column">
<div class="d-flex flex-column flex-grow-1">
<header>Header</header>
<div>Content</div>
<footer class="mt-auto">Footer</footer>
</div>
</body>
2) fill the height of the remaining screen space and aligning content to the middle of the parent element:
<body class="d-flex flex-column">
<div class="d-flex flex-column flex-grow-1">
<header>Header</header>
<div class="d-flex flex-column flex-grow-1 justify-content-center">Content</div>
<footer class="mt-auto">Footer</footer>
</div>
</body>
If you can deal with not supporting old browsers (that is, MSIE 9 or older), you can do this with Flexible Box Layout Module which is already W3C CR. That module allows other nice tricks, too, such as re-ordering content.
Unfortunately, MSIE 9 or lesser do not support this and you have to use vendor prefix for the CSS property for every browser other than Firefox. Hopefully other vendors drop the prefix soon, too.
An another choice would be CSS Grid Layout but that has even less support from stable versions of browsers. In practice, only MSIE 10 supports this.
Update year 2020: All modern browsers support both display: flex and display: grid. The only one missing is support for subgrid which in only supported by Firefox. Note that MSIE does not support either by the spec but if you're willing to add MSIE specific CSS hacks, it can be made to behave. I would suggest simply ignoring MSIE because even Microsoft says it should not be used anymore. Microsoft Edge supports these features just fine (except for subgrid support since is shares the Blink rendering engine with Chrome).
Example using display: grid:
html, body
{
min-height: 100vh;
padding: 0;
margin: 0;
}
body
{
display: grid;
grid:
"myheader" auto
"mymain" minmax(0,1fr)
"myfooter" auto /
minmax(10rem, 90rem);
}
header
{
grid-area: myheader;
background: yellow;
}
main
{
grid-area: mymain;
background: pink;
align-self: center
/* or stretch
+ display: flex;
+ flex-direction: column;
+ justify-content: center; */
}
footer
{
grid-area: myfooter;
background: cyan;
}
<header>Header content</header>
<main>Main content which should be centered and the content length may change.
<details><summary>Collapsible content</summary>
<p>Here's some text to cause more vertical space to be used.</p>
<p>Here's some text to cause more vertical space to be used (2).</p>
<p>Here's some text to cause more vertical space to be used (3).</p>
<p>Here's some text to cause more vertical space to be used (4).</p>
<p>Here's some text to cause more vertical space to be used (5).</p>
</details>
</main>
<footer>Footer content</footer>
Example using display: flex:
html, body
{
min-height: 100vh;
padding: 0;
margin: 0;
}
body
{
display: flex;
}
main
{
background: pink;
align-self: center;
}
<main>Main content which should be centered and the content length may change.

There's a ton of answers now, but I found using height: 100vh; to work on the div element that needs to fill up the entire vertical space available.
In this way, I do not need to play around with display or positioning. This came in handy when using Bootstrap to make a dashboard wherein I had a sidebar and a main. I wanted the main to stretch and fill the entire vertical space so that I could apply a background colour.
div {
height: 100vh;
}

In all sane browsers, you can put the "header" div before the content, as a sibling, and the same CSS will work. However, IE7- does not interpret the height correctly if the float is 100% in that case, so the header needs to be IN the content, as above. The overflow: auto will cause double scroll bars on IE (which always has the viewport scrollbar visible, but disabled), but without it, the content will clip if it overflows.
CSS Grid Solution
Just defining the body with display:grid and the grid-template-rows using auto and the fr value property.
* {
margin: 0;
padding: 0;
}
html {
height: 100%;
}
body {
min-height: 100%;
display: grid;
grid-template-rows: auto 1fr auto;
}
header {
padding: 1em;
background: pink;
}
main {
padding: 1em;
background: lightblue;
}
footer {
padding: 2em;
background: lightgreen;
}
main:hover {
height: 2000px;
/* demos expansion of center element */
}
<header>HEADER</header>
<main>MAIN</main>
<footer>FOOTER</footer>
A Complete Guide to Grids # CSS-Tricks.com
This is my own minimal version of Pebbl's solution. Took forever to find the trick to get it to work in IE11. (Also tested in Chrome, Firefox, Edge, and Safari.)
html {
height: 100%;
}
body {
height: 100%;
margin: 0;
}
section {
display: flex;
flex-direction: column;
height: 100%;
}
div:first-child {
background: gold;
}
div:last-child {
background: plum;
flex-grow: 1;
}
<body>
<section>
<div>FIT</div>
<div>GROW</div>
</section>
</body>
I wresteled with this for a while and ended up with the following:
Since it is easy to make the content DIV the same height as the parent but apparently difficult to make it the parent height minus the header height I decided to make content div full height but position it absolutely in the top left corner and then define a padding for the top which has the height of the header. This way the content displays neatly under the header and fills the whole remaining space:
body {
padding: 0;
margin: 0;
height: 100%;
overflow: hidden;
}
#header {
position: absolute;
top: 0;
left: 0;
height: 50px;
}
#content {
position: absolute;
top: 0;
left: 0;
padding-top: 50px;
height: 100%;
}
Why not just like this?
html, body {
height: 100%;
}
#containerInput {
background-image: url('../img/edit_bg.jpg');
height: 40%;
}
#containerControl {
background-image: url('../img/control_bg.jpg');
height: 60%;
}
Giving you html and body (in that order) a height and then just give your elements a height?
Works for me
You can actually use display: table to split the area into two elements (header and content), where the header can vary in height and the content fills the remaining space. This works with the whole page, as well as when the area is simply the content of another element positioned with position set to relative, absolute or fixed. It will work as long as the parent element has a non-zero height.
See this fiddle and also the code below:
CSS:
body, html {
height: 100%;
margin: 0;
padding: 0;
}
p {
margin: 0;
padding: 0;
}
.additional-padding {
height: 50px;
background-color: #DE9;
}
.as-table {
display: table;
height: 100%;
width: 100%;
}
.as-table-row {
display: table-row;
height: 100%;
}
#content {
width: 100%;
height: 100%;
background-color: #33DD44;
}
HTML:
<div class="as-table">
<div id="header">
<p>This header can vary in height, it also doesn't have to be displayed as table-row. It will simply take the necessary space and the rest below will be taken by the second div which is displayed as table-row. Now adding some copy to artificially expand the header.</p>
<div class="additional-padding"></div>
</div>
<div class="as-table-row">
<div id="content">
<p>This is the actual content that takes the rest of the available space.</p>
</div>
</div>
</div>
style="height:100vh"
solved the problem for me. In my case I applied this to the required div
Vincent, I'll answer again using your new requirements. Since you don't care about the content being hidden if it's too long, you don't need to float the header. Just put overflow hidden on the html and body tags, and set #content height to 100%. The content will always be longer than the viewport by the height of the header, but it'll be hidden and won't cause scrollbars.

Try this
var sizeFooter = function(){
$(".webfooter")
.css("padding-bottom", "0px")
.css("padding-bottom", $(window).height() - $("body").height())
}
$(window).resize(sizeFooter);
I had the same problem but I could not make work the solution with flexboxes above. So I created my own template, that includes:
a header with a fixed size element
a footer
a side bar with a scrollbar that occupies the remaining height
content
I used flexboxes but in a more simple way, using only properties display: flex and flex-direction: row|column:
I do use angular and I want my component sizes to be 100% of their parent element.
The key is to set the size (in percents) for all parents inorder to limit their size. In the following example myapp height has 100% of the viewport.
The main component has 90% of the viewport, because header and footer have 5%.
I posted my template here: https://jsfiddle.net/abreneliere/mrjh6y2e/3
body{
margin: 0;
color: white;
height: 100%;
}
div#myapp
{
display: flex;
flex-direction: column;
background-color: red; /* <-- painful color for your eyes ! */
height: 100%; /* <-- if you remove this line, myapp has no limited height */
}
div#main /* parent div for sidebar and content */
{
display: flex;
width: 100%;
height: 90%;
}
div#header {
background-color: #333;
height: 5%;
}
div#footer {
background-color: #222;
height: 5%;
}
div#sidebar {
background-color: #666;
width: 20%;
overflow-y: auto;
}
div#content {

}
div.fized_size_element {

Spinning off the idea of Mr. Alien...
This seems a cleaner solution than the popular flex box one for CSS3 enabled browsers.
Simply use min-height(instead of height) with calc() to the content block.
The calc() starts with 100% and subtracts heights of headers and footers (need to include padding values)
Using "min-height" instead of "height" is particularly useful so it can work with javascript rendered content and JS frameworks like Angular2. Otherwise, the calculation will not push the footer to the bottom of the page once the javascript rendered content is visible.
Here is a simple example of a header and footer using 50px height and 20px padding for both.
Html:
<body>
<header></header>
<div class="content"></div>
<footer></footer>
</body>
Css:
.content {
min-height: calc(100% - (50px + 20px + 20px + 50px + 20px + 20px));
}
Of course, the math can be simplified but you get the idea...
I found a quite simple solution, because for me it was just a design issue.
I wanted the rest of the Page not to be white below the red footer.
So i set the pages background color to red. And the contents backgroundcolor to white.
With the contents height set to eg. 20em or 50% an almost empty page won't leave the whole page red.

Issue in sticky footer content in html5

I have created simple webpage using html5 and css.
I have created sticky footer with 4 columns and each column have vertical navigation menu.
Here is my code:
<footer>
<div id="footer">
<div class="footer-column" id="footer_column1">
Home
</div>
<div class="footer-column" id="footer_column2">
about us
</div>
<div class="footer-column" id="footer_column3">
contact us
</div>
<div class="footer-column" id="footer_column4">
Blogs
</div>
</div>
</footer>
and this is for css:
#footer {
position:absolute;
clear:both;
bottom:0;
color:#000;
width:100%;
height: 50px;
background:#fff;
left:0;
}
.footer-column {
float: left; /* Push the div as far up-left as it can be put */
width: 25%; /* Make sure to subtract the padding */
padding: 10px; /* We want padding on all sides to make things look nice */
text-align:center;
}
Now page looks like : s22.postimg.org/l0l6y85o1/Untitled_1_copy.png
If i increase the height of footer, it will be hidden background of slideshow.
Can anyone help me, how to fix this. Thanks in advance.
You have given absolute positioning to footer so it will stay there, now your page is basically overlapping it. You should use relative layout for your page.
I would suggest you to use bootstrap for this. Here is a simple example or this.
Regarding z-index - If you will give higher z-index to your footer say 999999 then it will be on top (higher than other elements on page).
Z-index will not actually help you with positioning. Always something will be hidden. If you want your footer to be right at bottom of the page then do not use absolute positioning and it will be pushed down.
Try:
html {
position: relative;
min-height: 100%;
}
body {
/* Margin bottom by footer height */
margin-bottom: 100px;
}
#footer {
position: absolute;
bottom: 0;
width: 100%;
/* Set the fixed height of the footer here */
height: 100px;
}

How to remove the white space under my footer in Wordpress?

I have basic coding experience. In my Wordpress install, some of my pages have a blank white space under the footer that I would like to remove. I have tried several solutions but to no avail. The problem is persistent on chrome, Firefox, IE etc.
I'm not really sure of the cause, but the size of the white space changes depending on computer/browser/resolution.
As I am working in Wordpress I have access to custom CSS and source theme files, however, I would prefer to solve this problem with custom CSS.
I would like a footer that sticks to the bottom of the browser window with no whitespace below it.
Q. Please provide me with code/solution that will remove the white spaces below the footer on my website (preferably custom CSS method).
You can find an example of the white space on my website here. (try viewing on a browser resolution higher than 1280x800)
Solutions i've tried:
#footer {overflow: hidden;} didn't work
Putting html, body, parentDiv, childDiv, section, footer { height : 100%; } in my css but that didn't work
#copyright { padding-bottom: 20px;} "#copyright" is under the footer so this did reduce the whitespace to a point where it seemed it weren't present, but on taller browser windows the white space reappeared.
You have whitespace under the footer because the content is not sufficient to push it past the bottom of the monitor at higher resolutions.
I'd recommend using the Sticky Footer to handle this. It allows the minimum height of the body to be that of the browser, regardless of how little content is in the page.
The sticky footer solution requires some specific HTML to be included, and some basic CSS. Here's a Fiddle of Ryan Fiat's sticky footer in action using the code from his example.
The code goes like this:
HTML:
<body>
<div class="wrapper">
<p>Your website content here.</p>
<div class="push"></div>
</div>
<div class="footer">
<p>Footer content here</p>
</div>
</body>
CSS:
* {
margin: 0;
}
html, body {
height: 100%;
background-color:#eaeaea;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -155px; /* the bottom margin is the negative value of the footer's height */
border:solid 1px red;
}
.footer, .push {
height: 155px; /* '.push' must be the same height as 'footer' */
}
.footer {
border:solid 1px blue;
}
Looking at your markup, you can use your existing div class="clear"></div> as your .push div, then you only need to add the div class="wrapper"> around your content.
Try something like this
html {
height: 100%;
}
body {
height: 100%;
flex-direction: column;
min-height: 100vh;
display: flex;
}
footer {
flex-shrink: 0;
}
.futovac {
flex: 1;
}
<html>
<body>
<main></main>
<div class="futovac"></div>
<footer></footer>
</body>
</html>
DEMO: https://help.podio.com/hc/en-us
find you code on .footer you code will be like this,
.footer-top-content .widget_links ul li a {
border-bottom: 1px #4C4C4C solid;
background: #333;
color:#999;
replace this code with this one,
.footer-top-content .widget_links ul li a {
border-bottom: 1px #4C4C4C solid;
background: #333;
color:#999 !important;
overflow: hidden;
this helped mine. hope for you too guys..

Make a div fill the remaining dynamic height and scroll without javascript

I have a document structure that maintains the header at the top of the page and the footer at the bottom. It's working well as long as the content in the middle is less than the height of the window. If the content is too long, the footer gets pushed further down the page and a full body scrollbar is displayed.
How can I get the scrollbar to be limited to the content DIV.
Note that the content of the header and footer are not fixed so I don't know the height of those elements and can't set the top position of the content element as a fixed value. I've added a show/hide feature in the example to demonstrate this.
I'm trying to resolve this in pure CSS (avoiding Javascript). I know that using javascript, I could monitor changes to window size and element visibility, I could calculate the height of the header and footer and set fixed dimensions to the content element. But is there a non-javascript solution?
http://jsfiddle.net/sA5fD/1/
html { height: 100%; }
body {
padding:0 0;
margin:0 0;
height: 100%;
}
#main {
display:table;
height:100%;
width:100%;
}
#header, #footer {
display:table-row;
background:#88f;
}
#more {
display: none;
}
#content {
display:table-row;
height:100%;
background:#8f8;
}
It should work for all modern browsers, desktop, tablets and mobiles. For old browsers, a full body scrollbar would be ok.
If you add two wrap blocks:
<div id="content">
<div id="content-scroll-wrap">
<div id="content-scroll">
content...
Then use CSS:
#content-scroll-wrap {
position: relative;
height: 100%;
}
#content-scroll {
position: absolute;
top: 0; bottom: 0;
left: 0; right: 0;
overflow: auto;
}
http://jsfiddle.net/sA5fD/8/
Don't know about support in old browsers. IEs might need some fixes.
For future visitors:
HTML
<div class="parent">
<div class="child">
<div class="large-element> </div>
</div>
</div>
CSS
.parent {
height: 1000px
overflow-y: scroll;
}
.child {
background-color: royalblue;
height: auto;
}
.large-element {
height: 1200px;
}
In this scenario, the child element will create an overflow. Since the child's height is set to auto, it will stretch out to fill the container. If you had set it to 100%, it would only go 1000px, leaving some white space beneath!

This should work in all browsers :)

Difference between CSS sticky footer implementations?

I've found 2 different implementations of a CSS sticky footer:
Ryan Fait sticky footer - http://ryanfait.com/sticky-footer/
Steve Hatcher sticky footer - http://www.cssstickyfooter.com/
Could someone explain the difference between how each of them work?
And if there are other known implementations, could you please post a comment or edit this question?
They are pretty similar in terms of function. The first forces a div to the full height of the page and then give it a negative margin the size of the footer.
html, body {
height: 100%; /*set 100% height*/
}
.wrapper {
min-height: 100%; /*content 100% height of page */
height: auto !important;
height: 100%;
margin: 0 auto -142px; /* negative value causes wrappers height to become (height of page) minus 142px, just enough room for our footer */
}
.footer, .push {
height: 142px; /*Footer is the footer, push pushes the page content out of the footers way*/
}
What this does is makes sure that all content within the wrapping div is 100% of the page height minus the height of the footer. So that as long as the footer is the same size as the negative margin it will stick in the gap left and appear at the bottom of the element.
The second also forces the content to be 100% of the height of the page.
html, body {height: 100%;} /*set 100% height*/
#wrap {min-height: 100%;} /* make content 100% height of screen */
It then creates a space at the bottom of the main content the same size as the footer.
#main {overflow:auto;
padding-bottom: 150px;} /* wrapper still 100% height of screen but its content is forced to end 150px before it finishes (150px above bottom of screen) */
Then using position relative and a negative top margin forces the footer to appear 150px above its normal position (in the space it just made).
#footer {position: relative;
margin-top: -150px; /* Make footer appear 150px above its normal position (in the space made by the padding in #main */
height: 150px;
clear:both;}
Note: This only works so long as your page content is kept within .wrapper and #main inside #wrap respectively, and your footer is outside of these containers.
If you didn't understand any part of that leave me a comment and I'll try to answer it.
Edit: In response to user360122
HTML markup for first:
<html>
<body>
<div class="wrapper">
<!--Page content goes here-->
<div class="push">
<!--Leave this empty, it ensures no overflow from your content into your footer-->
</div>
</div>
<div class="footer">
<!--Footer content goes here-->
</div>
<body>
</html>
HTML markup for second:
<html>
<body>
<div id="wrap">
<div id="main">
<!--Page content goes here-->
</div>
</div>
<div id="footer">
<!--Footer content goes here-->
</div>
</body>
</html>
Remember to include the stylesheet and declare doctype .etc (these aren't full html pages).
There is an example in the bootstrap documentation which seems to be very simple: http://getbootstrap.com/examples/sticky-footer/
No wrapper or push needed.
html {
position: relative;
min-height: 100%;
}
body {
/* Margin bottom by footer height */
margin-bottom: 60px;
}
#footer {
position: absolute;
bottom: 0;
width: 100%;
/* Set the fixed height of the footer here */
height: 60px;
background-color: #f5f5f5;
}
