I'm trying to align a html-page with the bottom of the browser-window. This is my apporach:
<body>
<div class="outer-wrapper">
</div>
</body>
.outer-wrapper{
min-height: 950px;
width: 100%;
position: absolute;
bottom: 0;
}
The problem with this solution is that when the screen is smaller than 950px high, the top of the outer-wrapper disapears above the screen and no scroll is added. Both the body and the outer-wrapper has a background-image.
Here is a sample, as you can see, the top of the red box is above the body.
http://jsfiddle.net/C5Nce/1/
The following demo should work, if I understand what you want correctly:
http://jsfiddle.net/C5Nce/10/show/
I just used a media query to detect when the page is less than 550px and set the element to be pinned to the top instead:
#media screen and (max-height: 550px) {
.outer_wrapper {
top: 0;
}
}
I've coloured it green so you can tell when the query fires.
.outer {
position:absolute;
height:100%;
width:100%;
background-color:#aaaaaa;
margin:0;
padding:0;
}
.content {
position:relative;
width:90%;
height:90%;
background-color:#444444;
margin:5%;
}
.inner {
position:absolute;
height:20%;
width:100%;
background-color:#eeeeee;
bottom:0;
margin-bottom:10%;
}
<div class="outer">
<div class="content">
<div class="inner"></div>
</div>
</div>
http://jsfiddle.net/L8H9J/
1) Remove the margin-bottom style from the inner class
2) All the content you add inside the inner class will be aligned with the bottom
3) Because of the flow of the document in HTML, you cannot explicitly align them with the
bottom
4) You can use this trick to do so, but again all elements inside the inner class will be
with flow of position:static
5) There comes the use of JavaScript to determine suitable margins for each element inside
the inner class
Tip: Use percentages; although you want the wrapper to be of height ~950px, but if you can use percentages for the dimensions, you would really love watching your web applications scale with the browsers:
I would just give your outer-wrapper a height of 100% (along with html, body):
html, body {
height: 100%;
padding: 0;
margin: 0;
}
.outer-wrapper {
height: 100%;
width: 100%;
position: absolute;
bottom: 0;
overflow-y: auto;
background-position:bottom; //Edit
}
Then the outer-wrapper will always keep the body's height. There’s no need for the 950px height min because in the case that the viewport is too small you wanted for this to scroll and in the other case the viewport is bigger than 950px - well, it's bigger than 950px - that's a good thing.
Edit section from your code here
.outer_wrapper
{
background-color:red;
/*min-height: 550px;*/
margin-left: -75px;
top:auto;
bottom: 0;
position: absolute;
left:50%;
}
and you are specifying your red box is above the body, if you put it inside body it supposed to be placed like it as you also have specify min-height of container.

My footer will not stick to the bottom of the page in the latest Firefox, while it works in Chrome and IE11. From what I can tell the min-height:100% for the wrapper has no effect in Firefox.
HTML
<div id = "wrapper">
<div id = "content">
</div>
<div id = "push">
</div>
</div>
<div id = "footer"></div>
CSS
#wrapper{
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -235px;
}
#push{
height:235px;
}
#footer{
position:relative;
height:235px;
width:100%;
}
It's hard to say by the posted code but according to CSS level 2 spec:
10.7 Minimum and maximum heights: 'min-height' and 'max-height'
The percentage is calculated with respect to the height of the
generated box's containing block. If the height of the containing
block is not specified explicitly (i.e., it depends on content
height), and this element is not absolutely positioned, the percentage
value is treated as '0' (for 'min-height') or 'none' (for
'max-height').
Hence you should make sure that the parent of #wrapper has an explicit height. If the #wrapper is located in <body>, try specifying height: 100% on <body> and <html> elements as well:
html, body {
height: 100%;
}
Because a percentage value for height property is relative to the height of the generated box's containing block as well, in this case the <html>. Otherwise the value computes to auto.
In addition, using height: auto !important; and height: 100%; together doesn't make sense and they're pointless; So it's better to remove them.
#wrapper{
min-height: 100%;
margin: 0 auto -235px;
}
Finally if it didn't work, you could give the following approach a try:
Position footer at bottom of page having fixed header
Let's simplify what you have a little.
Your #push can be replaced with the pseudo element :after on your wrapper.
Remove the height on the wrap and avoid !important.
html,body needs to have a height of 100% in order for other elements to have percentage heights
Have an example!
HTML
<div class="wrap">
<!-- main content -->
</div>
<footer class="footer"></footer>
CSS
* {
margin: 0;
padding: 0;
}
html, body {
height: 100%;
}
.wrap {
min-height: 100%;
margin-bottom: -235px;
}
.wrap:after {
content: "";
display: block;
}
.footer, .wrap:after {
height: 235px;
}
.footer {
background: #F00;
}
If you are trying to have your your footer stick to the bottom, use:
#footer{
position:fixed;
bottom:0;
height:235px;
width:100%;
}
I just tried it with your code and verified that it works on the latest firefox.
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!
Here is a pen: https://codepen.io/meteora/pen/JJYoZM
This should work in all browsers :)
I need to have 3 divs, out of which 1 is set to width of 1000px and be in the middle of the page, and the other 2 should fill the screen width from the left and right of the main div. I want this to work on all screen resolutions but I can't find the way to do it.
My code so far (I used colors as a visual aid)-
css:
#leftside { background: red; float: left; width: 100%; position: relative; width: 100%; }
#rightside { background: blue; float: left; width: 100%; position: relative; }
#container { background: yellow; float: left; width: 1000px; position: relative; }
html:
<html>
<body>
<div id="leftside"> </div>
<div id="container">the content</div>
<div id="rightside"> </div>
...
So far it is not working. how do I make the "leftside" and "rightside" divs automatically adjust to what is left in the screen resolution - for any screen resolution?
Thanks for the help.
you can achive by doing this with css
#maindiv{
width:1000px;
}
#rightdiv, #leftdiv{
width:calc((100%-1000)/2);
}
#rightdiv{
//other styles
}
#leftdiv{
//other styles
}
test browser support for calc()
You'd have to inject some javascript code:
$content = $('.content');
$sidebar = ($(window).width() - $content.width()) / 2;
$('.leftside').css('width', $sidebar);
$('.rightside').css('width', $sidebar);
See demo
Then use media queries to change the middle div's width when the screen gets smaller.
One way is to put the divs in a table with one row and 3 cells. The table will have width 100% and you can set the width of the centre td.
I'm sure someone will suggest a better way in CSS though.
This is the page I am working on right now: http://jsfiddle.net/0xsven/hycRx/
I want the page to expand vertically to fill the whole screen so that the footer is always at the very bottom. I am not searching for a sticky footer! I want the page to expand to the bottom like in this picture.
Any idea if this is possible?
Update
I used some confusing words so I am trying to clarify my question:
I want my page to always fill out the viewport vertically, even if there is not enough content. As soon as there is enough content to even extend the viewport the page should be scrollable. In my tests a sticky footer always stays at the bottom of the viewport covering other elements, which I don't want to happen.
One solution I came up with is manipulating/resizing the paddings/margins with jquery so it fits the viewport. But I dislike using javascript for such things.
You can experiment with the position attribute, like this:
#footer{
background-color: #222;
position: relative;
bottom: 0;
}
#footer{
position: fixed;
bottom: 0;
}
The behaviour you're trying to emulate is that of the conventional CSS Sticky Footer.
Here's a simple example:
HTML
<div id="wrap">
<div id="main">
</div>
</div>
<div id="footer">
</div>
CSS
html, body {height: 100%;}
#wrap {min-height: 100%; *display:table; *height:100%}
#main {overflow:auto; padding-bottom: 150px;} /* must be same height as the footer */
#footer {
position: relative;
margin-top: -150px; /* negative value of footer height */
height: 150px;
clear:both;
}
/*Opera Fix*/
body:before {
content:"";
height:100%;
float:left;
width:0;
margin-top:-32767px;/
}
The following code has a DIV that needs to be positioned at the top of the container, another at the bottom and then the content needs to come through in the middle.
<div style="position:absolute; top:0; width:100%; height:40px"></div>
<div class="howto"></div>
<div style="position:absolute; bottom:0; width:100%; height:40px"></div>
So we don't know the height of the containing DIV. How without JS can the div with class howto have the height of the container DIV less the height of the absolute positioned div at the top and bottom so as to contain content between these 2 DIVs.
For what you wish to accomplish, this is one possible solution:
#tinkerbin: http://tinkerbin.com/QsaCPgR6
HTML:
<div class="container">
<div class="header"></div>
<div class="howto">
Has height set to auto. You may change that if you want to.
</div>
<div class="footer"></div>
</div>
CSS:
.container {
position: relative;
padding: 40px 0; /* top and bottom padding = .header and .footer padding*/
}
.header,
.footer {
position: absolute;
height: 40px;
width: 100%;
}
.header {
top: 0;
}
.footer {
bottom: 0;
}
.howto {
height: /*specifiy one if you wish to*/;
}
As far as I know there isn't a pure CSS way to do what you're trying to do without JS.
