trying to implement a dialog-box style behaviour using a separate div section with all the stuff inside it.
When the "dialog box" needs to be shown, it has to display at the center of the WINDOW, not in the center of the page, that is, REGARDLESS of the scroling position. Furthermore, the correct solution will not move the "dialog box" if the user scrolls the page.
In Chrome and FF this works using position='fixed' and centering the div in the intuitive way.
This does not seem to work in IE6 (apparently fixed is not supported there).
Any ideas?
If I were you I would do it using jQuery and I would suggest you try it out too. This should fit perfectly for jQuery based solution [jQuery Version][1] or try out
body {
font: 80% verdana, arial, helvetica, sans-serif;
text-align: center; /* for IE */
}
#container {
margin: 0 auto; /* align for good browsers */
text-align: left; /* counter the body center */
border: 2px solid #000;
width: 80%;
}
Try the method outlined here.
Use overflow-y and absolute positioning to emulate fixed positioning in IE6 using the following steps:
Create an absolutely positioned div and give it the desired top and left coordinates on the page
Set html {overflow-y: } to be hidden or visible instead of the default auto or scroll to eliminate the scrollbar for the absolutely positioned div
Set body{overflow-y: } to be auto or scroll to insert a new scrollbar for the body content
Set body { margin:0; height:100% } to make sure the content scrollbar goes the length of the page
Set top and left margins on the body to separate the content from the absolutely positioned div
Make sure the doctype is set to trigger Standards Mode in IE
Set the absolutely positioned div to top:50%; left:50%;
Add position:relative and the desired opacity to the container div
If the doctype is not set, move the html rules to the body tag, and the body rules to a wrapper div
<!DOCTYPE html>
<html>
<head>
<style>
body { margin:0; margin-left: 14em; }
#fixedbox { position: fixed; top: 1em; left: 1em; width: 10em; }

#container { height: 2000px; }

}
</style>

I have a sticky footer that uses the flexbox technique which works perfectly fine and expands when the content fills the page.
I'm now trying to add a conditional, based on a particular user, fixed position bottom navbar. i've applied margin-bottom to the footer which is fine when the content fits within the page however when the content grows i cannot scroll the page to the bottom and view the full footer. It seems the bottom-margin is not applied to the footer when the content grows to fill the page. Any help would be appreciated, example code and Codepen below.

padding: 20px;
}
.footer {

Setting height: 100% on html and body (as opposed to min-height) prevents the document height from exceeding the viewport height, so your additional content is overflowing scrollable area.
You could remove body from the 100%, leaving it on html, or add overflow: auto to the html/body rule so that the body element can scroll (as opposed to scrolling the window).
Edit: removing 100% height from body allows the footer to move off the bottom of the window. Updated accordingly.
html, body {
/* IE 10-11 didn't like using min-height */
height: 100%;
overflow: auto;
}
You also have a typo in your .conditionalNav rule:
hight:25px;
Out of curiosity, considering the example below, why does having the margin on the #container div cause a vertical scrollbar to appear in the browser? The container is much smaller in height than the body height which is set to 100%.
I have set the padding and margins to 0 for all elements except the #container. Note that I have deliberately omitted absolute positioning on the #container div. In this case how is the browser calculating the height of the body and how is the margin affecting it?
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
* { padding:0; margin:0;}
html, body { height:100%; }
#container
{
padding:10px;
margin:50px;
border:1px solid black;
width: 200px;
height: 100px;
}
</style>
</head>
<body>
<div id='container'>
</div>
</body>
</html>
Example also on JSFiddle
If you paint the backgrounds of html and body (giving each its own color), you'll quickly notice that body is being shifted down along with #container, and #container itself isn't offset from the top of body at all. This is a side effect of margin collapse, which I cover in detail here (although that answer describes a slightly different setup).
It's this behavior that's causing the scrollbar to appear, since you've declared body to have 100% the height of html. Note that the actual height of body is unaffected, as margins are never included in height calculations.
Based upon #BoltClock♦'s answer, I fixed it by zeroing the margin...
so
html,body, #st-full-pg {
height: 100%;
margin: 0;
}
works where id "st-full-pg" is assigned to a panel div (which further contained panel-heading and panel-body)
A bit late, but maybe it helps someone.
Adding float: left; to #container removes the scrollbar, as W3C says:
•Margins between a floated box and any other box do not collapse (not even between a float and its in-flow children).
html,body {
height: 100%;
margin: 0;
overflow: hidden;
}
This worked for me
adding float:left; is nice, but will interfere with central horizontal positioning using margin:auto;
if you know how big your margin is, you can account for that in your height percentage using calc:
height: calc(100% - 50px);
browser support is good, but only IE11+
https://caniuse.com/#feat=calc
/*removes default margin & padding*/
html, body{
padding: 0px !important;
margin: 0px !important;
}
/*sets body height to max; and allows scrollbar as page content grows*/
body{
min-height: 100vh;
}
I have found a solution: add padding: 1px 0; to body prevents vertical scrollbars to appear
For those who are coming here for an easier to understand answer that even includes code samples, this answer (copied from here) is for you.
No JavaScript or definite pixel values (such as 100px) are required, just, pure CSS and percentages.
If your div is just sitting there on its own, height: 50% will mean 50% the height of the body. Normally, the height of the body is zero without any visible content, so 50% of that is just, well, zero.
This is the solution (based on this) (uncomment the background lines to get a visualisation of the padding):
/* Makes <html> take up the full page without requiring content to stretch it to that height. */
html
{
height: 100%;
/* background: green; */
}
body
{
/*
100% the height of <html> minus 1 multiple of the total extra height from the padding of <html>.
This prevents an unnecessary vertical scrollbar from appearing.
*/
height: calc(100% - 1em);
/* background: blue; */
}
/* In most cases it's better to use stylesheets instead of inline-CSS. */
div
{
width: 50%;
height: 50%;
background: red;
}
<div></div>
The above was written so that there would still be the usual padding. You could set the dimensions of the red div to 100% and still see padding on each side/end. If you don't want this padding, use this (although it doesn't look nice, I recommend you stick with the first example):
/* Makes <html> take up the full page without requiring content to stretch it to that height. */
html, body
{
height: 100%;
}
/* You can uncomment it but you wouldn't be able to see it anyway. */
/*
html
{
background: green;
}
*/
body
{
margin: 0;
/* background: blue; */
}
/* In most cases it's better to use stylesheets instead of inline-CSS */
div
{
width: 50%;
height: 50%;
background: red;
}
<div></div>
I saw this problem fixed before where you put all the contents of body in a div called wrap. Wrap's style should be set to position: relative; min-height: 100%;. To position #container div 50px from the top and left put a div inside wrap with a padding set to 50px. Margins will not work with wrap and the div we just made, but they will work in #container and everything inside it.
here's my fix on jsfiddle.
you can add non-breaking space into the body tag.
<body> <othertags>...</body>
html, body {
height: 100%;
overflow: hidden;
}
If you want to remove the body scrolling add the following style:
body {
height: 100%;
overflow: hidden;
}
Inspired by #BoltClock, I tried this and it worked, even when zoom out and in.
Browser: Chrome 51
html{
height: 100%;
}
body{
height: 100%;
margin: 0px;
position: relative;
top: -20px;
}
I guess body was shifted down 20px.
It works for me:
html,
body {
height: 100%;
height: -webkit-fill-available; // Chrome
}
// Firefox
#-moz-document url-prefix() {
body {
box-sizing: border-box;
margin: 0;
padding: 1px;
}
}
Add overflow: hidden; to html and body.
html, body {
height: 100%;
overflow: hidden;
}
I found a quick solution: try set height to 99.99% instead of 100%
I made a button inside the div body and i want to show it on the right side of my div but when i zoom the page it get outside from the div body need help?
<style>
.mydiv
{
max-width:65%;
min-height:30px;
margin-left:20%;
margin-right:16%;
}
.a
{
max-width:100px;
height:20px;
position:relative;
margin-left:220px;
}
</style>
<html>
<div class="mydiv">
<button class="a">example</button>
</div>
</html>
I think this is happening because (for your div)
max-width:65%;
in the css...if you zoom in enough the button (which has max-width of 100px) is now exceeding the width of your div. Try setting your div to a number of pixels larger than 100px. If you want the button on the right side of the div, try setting the width to a number such as 300px.
max-width:300px;
then try zooming in. Also note IE6 and earlier do not support max-width.
You don't show us much context, but it may work positioning the button to the right using position:absolute;right:0;. (Note you'll need position:relative; on the container to keep it inside the container element)
.mydiv {
position: relative;
max-width: 65%;
min-height: 30px;
margin-left: 20%;
margin-right: 16%;
background: tan;
}
.a {
position: absolute;
right: 0;
max-width: 100px;
height: 20px;
}
I have a page with only a couple of lines of content. I want the footer to be pushed to the bottom.
<div id="footer"></div>
I don't want to use
#footer
{
position:fixed;
bottom:0;
}
AKA Sticky Footer
Is this possible without jQuery?
any suggestions?
This Flexbox solution is neater and far easier to implement:
HTML
<body>
<div class="content">
content
</div>
<footer class="footer"></footer>
</body>
CSS
html, body {
height: 100%;
}
body {
display: flex;
flex-direction: column;
}
.content {
flex: 1 0 auto;
}
.footer {
flex-shrink: 0;
}
Just ensure you wrap the necessary divs inside the body.
Update 2021 - CSS GRID
Here is a solution using CSS Grid, this is by far the best way to do it on 2021.
html, body {
margin: 0;
height: 100%;
}
body {
display: grid;
grid-gap: 10px;
grid-template-columns: 1fr;
grid-template-areas: "main" "footer";
grid-template-rows: 1fr 80px;
}
main {
background-color: #F8BBD0;
grid-area: main;
}
footer {
background-color: #7E57C2;
grid-area: footer;
}
<body>
<main>The content</main>
<footer>Footer</footer>
</body>
Old Answer
There is another sticky footer by Ryan Fait that doesn't use position fixed:
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important; /* This line and the next line are not necessary unless you need IE6 support */
height: 100%;
margin: 0 auto -155px; /* the bottom margin is the negative value of the footer's height */
}
.footer, .push {
height: 155px; /* .push must be the same height as .footer */
}
Here is a solution that does not require that the footer be placed outside of the main wrapper element, which is how most people structure their pages.
html,
body {
margin: 0;
height: 100%;
}
.wrapper {
box-sizing: border-box;
position: relative;
padding-bottom: 1em; /* Height of footer */
min-height: 100%;
}
header {
background-color: #cff;
}
footer {
position: absolute;
bottom: 0;
width: 100%;
color: #fff;
background-color: #000;
}
<div class="wrapper">
<header>I am the header.</header>
<article>I am content that doesn't fill the page. The footer will appear at the bottom of the browser window. However, when I do fill the page, you will need to scroll down to see the footer.</article>
<footer>I am the footer.</footer>
</div>
Explanation
The wrapper element will fill 100% of the viewport height. (You could also use 100vh for the wrapper if you don't want to set the height of the html and body elements.) The wrapper also has a bottom padding to create a placeholder for the footer to sit.
The footer is absolutely positioned to the bottom of the wrapper and sits in the placeholder created by the wrapper's bottom padding.
This means that when the page does not have scrollbars, the footer will be positioned at the very bottom. However, when there is enough content for scrollbars to appear, the footer will be pushed down below the content.
(The color and background-color CSS properties in the example are for decoration only, obviously. They are included so that when you run the code, you can clearly see the separated sections.)

You also need to include this conditional style in the <head> of your HTML file to feed this style to IE 6 and lower and 8 and higher.
<!--[if !IE 7]>
<style type="text/css">
#wrap {display:table;height:100%}
</style>
<![endif]-->
*/
Another way to do this if you don't know the footer size is to use javascript and css
html, body{
height:100%;
height:100%;
}
#footer{
background-color: #292c2f !important;
position:absolute;bottom:0px;
}
and Javascript part
$(document).ready(function(){
if ($(document).height() > $(window).height()) {
$('#footer').css('position', 'relative');
}
});
You can do this with another approach just easily by setting min-height on the tag before your footer tag.
.the-tag-before-footer{
min-height:30%;
}
I tried a lot of approaches, but results were different when page was totally fill or not. The simplest and efficient solution is to use flex.
html, body {height: 100%;}
body {display: flex; flex-direction: column;}
.content {flex: 1 0 auto; padding: 20px;}
.footer {flex-shrink: 0; padding: 20px;}
<div class="content">
<h1>The GOAT Footer with Flexbox</h1>
<p>You can add content to test with a full page</p>
</div>
<footer class="footer">
The GOAT Footer
</footer>
Credits to CSS Trick
First wrap all of your main content in a div element and give it a class of “wrapper” (or call it whatever you want).
HTML:
<body>
<div class="wrapper">
<h1>Main Content</h1>
</div>
<footer>
<p>Footer Content</p>
</footer>
</body>
Now, make sure you give your footer a height.
Then use the calc() function to set the height of your wrapper equal to the height of the viewport (display), minus the height of the footer.
.wrapper {
min-height: calc(100vh - 50px);
}
footer {
height: 50px;
}
Now, if you have extra margins on your wrapper content you will have to increase the amount of pixels you subtract from the viewport height to reflect that. Other than that, this is a super easy and quick fix. No javascript needed, and only two CSS rules.
The problem is simple to solve for anyone using Bootstrap 4 or higher, just include this snippet on your website:
<script>
$(document).ready(function(){
if ($('body').height() < $(window).height()) {
$('footer').addClass('position-absolute bottom-0');
} else {
$('footer').addClass('position-static');
}
});
</script>
Here we check if the height of the BODY tag is less than the height of the browser window, if positive we place the footer at the bottom of the page and if negative we make the footer static and it will remain where it is. You don't need to change your current code, you just need to include this javascript in your page or package, remembering that to work the <body> tag must have position: relative, if you haven't changed the tag's "position" property in CSS <body>, you don't need to do anything as it is the default value.
Make sure to include the code after jquery, without jquery it won't work.
If you are not using the <footer> tag, you should change the $('footer') selector as appropriate.
I'm trying to align a 'div' attribute to the center of the page (horizontally). The problem is that whatever attributes I've used, the 'div' continues to be aligned to left. The 'div' which I am reffering to, is the page 'div' of the webpage, which is inside the 'html' and the 'body' attributes. Here's the CSS code:
#page{
margin-top:20px;
margin-bottom:20px;
margin-left: auto;
margin-right:auto;
border-color: black;
border-style: solid;
border-width: thin;
overflow:auto;
padding-bottom: 10px;
padding-top: 0px;
width:1200px;
background-color:#ffffff;
font-family:Arial, Helvetica, sans-serif;
color:black;
font-size:12px;
height:700px;
}
and the 'html', 'body' CSS code is the following:
html,body {
background-color:#FFFFFF;
margin-left: auto;
margin-right: auto;
}
Note that if I remove the "overflow" property, the div is aligned to the center of the page (although, it overlays the menu which is on top of it) but I need the "overflow" property to automatically add scrollbars if the width/height of the page which would be displayed inside this div is greater than those specified in the CSS.
I haven't coded anything in awhile, however normally when I am creating a centered page:
html, body { width: 100%; height: 100%; margin: 0 auto; text-align: center; }
Then for the div:
#page { width: 900px; overflow: hidden; text-align: left; margin: 20px 0 20px 0; }
That may or may not work, like I said, it has been awhile.
In order to margin:auto works in your case is required to have a defined width/height for your main containers which are HTML and BODY
IMPORTANT:Both HTML and BODY elements must be ruled with the width/height properties
Do as follows
html,body {
background-color:#FFFFFF;
width:100%;
height:100%;
}
and watch this fiddle
It seems your div is filling full screen width. So center alignment will not have any visible effect on the div. Try to use a span instead.
Following will NOT work
<body style="text-align:center">
<div>Foo</div>
</body>
Following should work
<div style="text-align:center">
<span>Foo</span>
</body>
<div style="margin:0px auto;">sfsfsafafas</div>
Use this code surely it will make the div to center.
Simple:
HTML
<div id="page"></div>
CSS
#page {
width: 350px; height: 400px; border: 1px solid #000; margin: auto
}
jsFiddle example
You might also look at the "left" and "right" attributes for centering a if you are trying to center horizontally.
For instance, if your width was 60% of the page (width:60%), you could set (left:20%) and (right:20%) which MAY center it, however that depends on how your div is positioned. (position:absolute) or (position:relative).
(position:absolute) with the above width, left, and right should center horizontally.
There is also <center> enter code </center> within HTML that has worked for me in the past.
I'm not a guru with this though, so I don't know what "best practice" to use in your case.
