I am writing some css code for a school website that looks like this
body{
background:#000099 url('repeat.png') repeat-x;
margin-bottom:50px;
}
div.wsite-theme{
background-color:#FFFFFF;
border-top:5px solid #AAAAAA;
}
div.wsite-header{
background:#DDDDDD;
border-radius:5px;
}
#wrapper {
width:960px;
margin:0pt auto;
}
#content{
width:850px;
min-height:694px;
position:absolute;
left:98px;
top:150px;
}
#content-main{
width:100%;
min-height:594px;
position:absolute;
top:0px;
}
#navigation{
min-height:1px;
position:absolute;
left:98px;
top:90px;
line-height:2px;
padding:10px 10px;
width:850px;
}
#header{
width:850px;
height:150px;
position:absolute;
top:5px;
left:98px;
}
#footer{
width:100%;
height:100px;
background:#DDDDDD;
position:absolute;
bottom:0px;
border-top:5px solid #AAAAAA;
}
with html that looks like this:
<html>
<head>
<title>{title}</title>
<link rel="stylesheet" type="text/css" href="main-style.css" />
</head>
<body>
<div id="wrapper">
<div id="header" class="wsite-header">
<h1 class="title1">{title}</h1>
</div>
<div id="navigation">
{menu}
</div>
<div id="content">
<div id="content-main" class="wsite-theme">
{content}
</div>
<div id="footer">
{footer}
</div>
</div>
</div>
</body>
</html>
(ignore content in curly bracers. it for the website editor our school makes us use)
So when i go on my page and type in the content it re-sizes and goes behind the footer . However what i intend for it to do is push the footer down as it re-sizes to fit the content. Earlier it was behaving this way, so what am i doing wrong?
EDIT: i guess i wasn't clear enough at first,i want the parent #content div to resize with the content main div so the footer is pushed down
Why are you using absolute position at all? Remove all of the position: absolute from all of your DIVs they are not necessary. Position them using margins instead and you will not have a problem with the DIVs changing size.
As Mathew mentioned, when you use the position: absolute property, it takes that element out of the flow of the document so it will not affect the elements around it. All of your DIVs are in the order you want them displayed, there is no need for absolute positioning on any of them.
Just took out the positioning and messed with the padding of the wrapper to get the same thing you are trying - http://jsfiddle.net/n3Xqx/
Don't use position: absolute;, it takes things out of the regular document flow.
EDIT: If you need to give more vertical spacing between the header/footer/content areas, then use margin
Add position relative to the wrapper.
Replace position absolute to relative for content and footer.
#wrapper {
width: 960px;
margin: 0pt auto;
position: relative;
}
#content {
width: 850px;
min-height: 694px;
left: 98px;
top: 150px;
position: relative;
}
#content-main {
width: 100%;
min-height: 594px;
position: relative;
top: 0px;
}
#footer {
width: 100%;
height: 100px;
background: #DDDDDD;
bottom: 0px;
border-top: 5px solid #AAAAAA;
position: relative;
}

I'm looking for a way to create a div that has a relative size, adjusted to the browser's height. Problem is that I dont really know where to start, or how to do it.
Basically I will have a header, which will be 50px heigh, and the relative div below there. Below that div, theres another div that HAS to be 50px inside the screen (Without scrolling). More content of that div, or another div (I dont mind which one) will be outside the screen.
So if the browser is 1000px heigh, 100px will be spend for the top and bottom divs. That means the relative div must be 900px heigh.
To support the idea I have made a simple image of what I'm willing to achieve: (Yeah, paint skills, got no Photoshop at my current location)
The orange border would represent the size of the complete page.
I know this is pretty easy to do with JavaScript, that wouldn't be a challenge for me, but I'm trying to find a CSS-only solution if possible. Any ideas?
An idea, using % instead of px for header and footer : here
<div id='header'></div>
<div id='content'>
<div id='scrollable'>this is my content</div>
</div>
<div id='footer'></div>
And CSS
body {
height:100%;
}
#header {
width:100%;
height:15%;
position:absolute;
top:0;
background:red;
margin:0;
}
#footer {
width:100%;
height:15%;
position:absolute;
bottom:0;
background:blue;
}
#content {
position:absolute;
width:100%;
top:15%;
height : 70%;
background:yellow;
overflow-y:auto;
}
#content #scrollable {
min-height:100%;
}
So I think this is what you want
<div id="scrn">
<div id="top"></div>
<div id="bottom"></div>
</div>
Then some CSS
#scrn {
height: 1700px;
width: 100%;
position: relative;
}
#top {
height: 50px;
width: 100%;
position: fixed:
top: 0px;
}
#bottom{
height: 50px;
width: 100%;
position: fixed;
bottom: 0px;
}
This looks right I think? Also I put the position: relative and height in because I am not 100% sure what you are trying to achieve with it.
Ok! Here's a technique I've used a bunch- this will work best if you don't fix the height of your relative positioned div. Based on your description, this is not the intent so it should work fine.
Basic Markup:
<body>
<header>DIV 1 - 50PX</header>
<div class="main">MAIN STUFF - RELATIVE</div>
<footer>DIV 2 - 50PX</footer>
</body>
CSS:
body, html{
width:100%;
height:100%;
}
body{
margin:0;
positino:relative;
}
header{
position:absolute;
width:100%;
height:50px;
top:0;
left:0;
background:#666666;
color:#ffffff;
z-index:10;
}
footer{
position:absolute;
width:100%;
height:50px;
bottom:0;
left:0;
background:#555555;
color:#ffffff;
z-index:10;
}
.main{
position:relative;
box-sizing:border-box;
padding:50px 1em;
height:150%; /* this is to simulate your dynamic content */
background:#cccccc;
}
http://jsfiddle.net/xdeQ6/1/
Adding padding to the main content div will make sure that your actual content at the top and bottom of your page is not hidden behind the header and footer divs.
Here is my approach:
header, footer {
background: #f00;
position: fixed;
width: 100%;
height: 50px;
left: 0;
}
header {
top: 0;
}
footer {
bottom: 0;
}
#content {
margin: 50px 0;
}
See my fiddle: http://jsfiddle.net/Vw97D/1/
Does it meet your expectations?
I’m trying to drift away from using tables and I'm now trying to create a simple div-based layout - header, content, footer divs with 100% width and no parent div. But I'm having a little problem with it. My content and footer divs overlap header div if I ever insert anything there. They appear right in the middle of the header div. If they are empty they appear normally. But the moment I insert header image in it the problem starts.
I tried to change float and display properties, but it gives me strange output. Can anyone help me position them vertically one after another?
Here is the HTML code:
<div id="topDiv"> topmenu</div>
<div id="headerDiv">
<div class="innerDiv"><img src=" photos/header.jpg" /></div>
</div><br /><br />
<div id="contentsDiv"> content</div>
<div id="footDiv"> footer </div>
And here are the css styles:
div#topDiv{
width:100%;
height:20px;
background-color:#800000;
text-align:center;
margin: 0px;
position:absolute;
}
div#headerDiv{
width:100%;
position:absolute;
background-color:#0FF;
text-align:center;
margin: 0px;
}
div#contentsDiv{
width:100%;
margin: 0px;
text-align:center;
background-color:#0CC;
position:absolute;
}
div#footDiv{
width:100%;
margin: 0px;
text-align:center;
background-color:#CF3;
position:absolute;
}
.innerDiv{
width:930px;
height:100px;
margin:auto;
background-color:#C30;
position:relevant;
}
You are using absolute and relative positioning a lot
and they are making your layout look Bad and elements are over lapping.
Also you don't need to define margin and every other properties many times
html, body{
width 100%;
height:100%;
margin:0px;
padding:0px;
}
div{
display:block;
margin:auto;
}
Horizontal Layout
CSS-Reset
Vertical Layout
Just remove all position:absolute from CSS rules and you are done.
Here is a solution for you. You don't need to specify width=100 Without defining a width, it is 100% by default. Simply specify the width you want for the body and every other container will be that width. float: left; will prevent containers from stacking vertically. They will actually stack horizontally.
Rather than using many Ids for Div, you can simplify the tags with HTML5 tags in such a way as below.
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<style type="text/css">
body {
margin: 0 auto;
}
menu {
height: 20px;
background-color: #800000;
text-align: center;
margin: 0px;
}
header {
background-color: #0FF;
text-align: center;
margin: 0px;
}
article {
margin: 0px;
text-align: center;
background-color: #0CC;
}
footer {
margin: 0px;
text-align: center;
background-color: #CF3;
}
section {
height: 100px;
margin: auto;
background-color: #C30;
}
</style>
</head>
<body>
<menu>topmenu</menu>
<header>Header
<article>
<img src="http://www.psdgraphics.com/wp-content/uploads/2009/04/1-google-logo-tutorial.gif" />
</article>
</header>
<section>content</section>
<footer>footer </footer>
</body>
</html>
My HTML structure is basically this -
<div id="header">
<div class="container">
</div>
</div>
<div id="content">
<div class="container">
</div>
</div>
<div id="footer">
<div class="container">
</div>
</div>
Ignore any elements except <div id="header">
I want to align <div class="container"> inside <div id="header"> at exactly bottom center. I'm using the following CSS code-
#header{ width:1062px; height:326px; background-color:#110000; text-align:center; position:relative; }
#header .container{ width:940px; height:262px; background-color:#220000; margin:0px auto; position:absolute; bottom:0px; }
There are height differences between the parent (#header) and child (#header .container) DIVs. Removing position:absolute; from the child centers it but it sticks to the parent's top instead of bottom. Keeping position:absolute; sticks it at the bottom but aligns it to the left.
How do I align it both center AND bottom at the same time?
I tried all the solution above but it didn't work when you resize the browser window. This solution is mostly to be applied when you don't know the element's width. Or if the width is changed on resize.
After making some research I tried the following and it worked perfectly on all screen sizes.
#somelement {
position: absolute;
left: 50%;
bottom: 0px;
-webkit-transform: translateX(-50%);
transform: translateX(-50%)
}
I shared this for anyone still facing this issue.
try in this way:
#header .container{
width: 940px;
height: 262px;
background-color: #220000;
position: absolute;
bottom: 0 ;
left: 50%;
margin-left: -470px;
}
try this
#header .container {
width: 940px;
height: 262px;
background-color: #220000;
margin: 0px auto;
position: absolute;
bottom: 0px;
left: 61px;
}
use this:
#header{
width:1062px; height:262px; background-color:#110000; text-align:center;
position:relative;text-align: center; vertical-align: bottom;padding-top:64px;
}
#header .container{
width:940px;
height:262px;
background-color:#999000;
margin:0px auto;
bottom:0px;
margin-bottom: 0px;
padding-top: 0px;
}
Here the jsfiddle
UPDATE:
As DenisVuyka said in comment, i should add that the above sample was as answer to this particular question with fixed height for DIV.
If you want that height of DIV don't break up things then for example you should use padding-top:10%; in the #header and height:100% in #header .container CSS.
#header{
width:462px; height:262px; background-color:#110000; text-align:center;
position:relative;text-align: center; vertical-align: bottom;padding-top:10%;
}
#header .container{
width:300px;
height:100%;
background-color:#999000;
margin:0px auto;
bottom:0px;
margin-bottom: 0px;
padding-top: 0px;
}
Here is a demo: http://jsfiddle.net/d6ct6/ .
I was trying to get this to work in my project as well. I've edited this jsfiddle:
http://jsfiddle.net/d6ct6/
<div id="header">
<div class="container">
</div>
</div>
#header {
height:100vh;
background-color:#110000;
position:relative;
}
#header .container{
width:300px;
height:40px;
background-color:#999000;
bottom:0px;
position:absolute;
left:calc((100% - 300px)/2);
}
But I've found this only works when the width of .container is fixed.
If the width of .container is not fixed you would need javascript to find it's width and then change that width in the calc.
When the widths are responsive, use this:
HTML
<div id="header">
<div id="container">
</div>
</div>
CSS
#header {
height:100vh;
background-color:#110000;
position:relative;
}
#container{
width:300px;
height:40px;
background-color:#999000;
bottom:0px;
position:absolute;
}
JS
$(document).ready(function () {
var parentWidth = $('#header').width();
var trapWidth = $('#container').width();
var deadCenter = (parentWidth - trapWidth);
var deadHalf = Number( deadCenter / 2 );
$('#container').css("right", deadHalf);
});
In case you care more about having the inside div aligned in the center and can manually set the vertical alignment.
DEMO Height I used was first div height - second div height.
#header .container{ width:940px; height:262px; background-color:red; margin:0 auto; position:relative; top: 64px; }
I would take advantage of CSS table display properties and do the following:
#header {
width:1062px;
height:326px;
background-color:#110000;
text-align:center;
display: table-cell;
vertical-align: bottom;
}
#header .container {
width:900px;
height:262px;
background-color:#cccccc;
color: white;
display: inline-block;
}
Set the #header block to display: table-cell and set vertical-align: bottom to align the child's bottom edge to the bottom edge of the parent.
The child .container element had display: inline-block and this will allow it to respond the text-align: center property of the parent.
This will work regardless of the width of the child .container.
Demo fiddle: http://jsfiddle.net/audetwebdesign/p9CxE/
This same problem was bedevilling me for an hour or so, until I realised I could add an intermediary div; this separated the vertical alignment issue from the centering.
.dparent {
border: 1px solid red;
width: 300px;
height: 300px;
position: absolute;
}
.dchild {
border: 1px solid blue;
margin-left: auto;
margin-right: auto;
width: 200px;
height: 100px;
bottom: 0px;
position: relative;
}
.dmid {
border: 1px solid green;
width: 100%;
position: absolute;
bottom: 0;
<div class="dparent">
<div class="dmid">
<div class="dchild"></div>
</div>
</div>
Do the vertical alignment first, with an absolute position and the 0 bottom. Then do the centering with margin-left and margin-right set to auto.
You might try this solution for any concerned width:
width:100%;
position:absolute;
bottom: 5px;
left:50%;
margin-left:-50%;
Good luck!
i have a mind bobbling question.
I need a 100% width, 100% height container with 20px margin that expands with content. Is this at all possible? The closest i got was with this method:
#container {
position:absolute;
top:0;
bottom:0px;
left:0;
right:0;
margin:20px;
}
but then it wont expand in height with content.
Anybody know the divine technique for this?
I'm pretty sure it isn't possible to do with a single element, but if you don't mind having 3 spacer div elements, this solution works in all browsers:
<html>
<head>
<style type="text/css">
* {
margin: 0;
}
html, body {
height: 100%; padding: 0; /* padding 0 is for jsfiddle */
}
#wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin-left: 20px;
margin-right: 20px;
margin-bottom: -20px; /* the bottom margin is the negative value of the spacer height */
background-color: #ccc;
}
.spacer.edge {
background-color: white; /* same as body background */
}
.spacer {
height: 20px;
}
</style>
</head>
<body>
<div id="wrapper">
<div class="spacer edge"></div>
<!-- content here -->
<div class="spacer"></div>
</div>
<div class="spacer edge"></div>
</body>
</html>
Here's a fiddle to play with: http://jsfiddle.net/dTyTW/
I you want to expand the div with the content , then you need to set position : relative and in order to stick towards the bottom padding-bottom also need to be set.
#container {
position:relative;
top:20px;
bottom:20px;
left:20px;
right:20px;
padding-bottom: 80%;
border:1px solid red;
}
Values can be adjusted as per the requirement.
Try here
Remove the margin and give each position a 20px.
Also remove the bottom.
Add padding-bottom:20px;
#container {
position:absolute;
top:20px;
left:20px;
right:20px;
padding-bottom:20px;
}
http://jsfiddle.net/jasongennaro/w7dQP/3/
EDIT
If you are not opposed to using some jQuery, you could also do this
var h = $(document).height();
var h2 = $('#container').height();
if(h2 < h){
$('#container').height(h);
}
This ensures that if the div is smaller than the browser viewport, it will expand to fit it.
Once the text is as big or bigger, the styles will take care of it.

Use the padding property... look up the box model.
I have a div called header that is set up with a fixed position. The problem is when I scroll the page the content of the page shows up behind the header (the header is transparent).
I know a lot about css, but cannot seem to figure this one out. I have tried setting overflow to hidden, but I knew it wouldn't work (and it didn't).
This is very hard to explain, so I did the best I could.
html:
<div id="header">
<div id="topmenu">Home | Find Feeds | Subscriptions</div>
</div>
<div id="container">
<div id="content">
testing
</div>
</div>
css:
#header {
margin:0 auto;
position: fixed;
width:100%;
z-index:1000;
}
#topmenu {
background-color:#0000FF;
height:24px;
filter: alpha(opacity=50);
opacity: 0.5;
}
#leftlinks {
padding: 4px;
padding-left: 10px;
float: left;
}
#rightlinks {
padding: 4px;
padding-right: 10px;
float: right;
}
#containerfixedtop {
width: 100%;
height: 20px;
}
#contentfixedtop {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height:20px;
}
#container {
position: relative;
top: 68px;
width: 100%;
height: 2000px;
overflow: auto;
}
#content {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height: 2000px;
}
Here's a screenshot of the problem:
Just coming to this late, but in case anyone else runs across this in the future, here's your fix.
Your CSS Code:
.wrapper {
width:100%;
position:fixed;
z-index:10;
background:inherit;
}
.bottom-wrapper {
width:100%;
padding-top:92px;
z-index:5;
overflow:auto;
}
Your HTML:
<div class="wrapper">
...your header here...
</div>
<div class="bottom-wrapper">
...your main content here...
</div>
This will provide you with a header that cleanly matches your site, and floats at the top. The main content will scroll free of the header, and disappear when it passes the header.
Your .bottom-wrapper padding-top should be the height of your header wrapper's content.
Cheers!
You are probably looking for z-index. It allows you to specify the vertical order of elements on the page, so an element with z-index: 10 is floating above (visually) an element with z-index: 5.
Give the content z-index: 5 and see if it works.
I was having a similar issue, and found a solution for my case. It should apply whether you are using a full screen background image, or a solid color (including white).
HTML
<div id="full-size-background"></div>
<div id="header">
<p>Some text that should be fixed to the top</p>
</div>
<div id="body-text">
<p>Some text that should be scrollable</p>
</div>
CSS
#full-size-background {
z-index:-1;
background-image:url(image.jpg);
background-position:fixed;
position:fixed;
top:0px;
left:0px;
width:100%;
height:100%;
}
#header {
position:fixed;
background-image:url(image.jpg);
height:150px;
width:100%;
}
#body-text {
margin-top:150px;
}
This gives me the look of a full page image with a transparent fixed header and when the body content scrolls, it hides behind the header. The images appear seamless.
You could do the same thing with a solid color background, though, arguably, it would have been easier.
2 notes: the header has a set height, I have only tested in FF and Chrome.
Just came up with a new solution to this type of problem that I'm quite happy with.
Use clip-path on the content that needs to hide behind the transparent element. Then update the clip-path dynamically with js on window scroll.
HTML
<div id="sticky">Sticky content</div>
<div id="content">
<!-- any html inside here will hide behind #sticky -->
</div>
JS
window.addEventListener("scroll",function(){
const windowScrollTop = window.scrollTop;
const elementToHide = document.getElementById("content");
elementToHide.style.clipPath = `inset(${windowScrollTop}px 0 0 0)`;
});
Dynamic sticky content
In my case I had an element that I switched to position: sticky after scrolling past it. The #sticky content needs to be relative to the dom elements that came before it until we have scrolled far enough. Here's how I accounted for that:
HTML
<div id="otherStuff">Here's some other stuff</div>
<div id="sticky">Sticky content</div>
<div id="content">
<!-- any html inside here will hide behind #sticky -->
</div>
JS
window.addEventListener("scroll",function(){
const windowScrollTop = window.scrollTop;
const stickyElement = document.getElementById("sticky");
const elementToHide = document.getElementById("content");
const stickyElementTop = stickyElement.getBoundingClientRect().top
if(windowScrollTop >= stickyElementTop){
stickyElement.style.position = "sticky";
elementToHide.style.clipPath = `inset(${windowScrollTop - stickyElementTop}px 0 0 0)`;
}
else {
stickyElement.style.position = "relative";
elementToHide.style.clipPath = "none";
}
});
I fixed this problem using the background property with a color, you can use var even if you'd like to
.header{
width:100%;
position:fixed;
z-index:10;
background:blue;
/* background: var(--my-var-value); You can do this if needed*/
}
Does #header have a set height?
#header {position: fixed; height: 100px; }
#container {position: absolute; top: 100px; bottom: 0; overflow: auto; }
Pretty sure this wouldn't work in IE though...
Fix the position of the content div below the header + overflow-y the content div.
I have fixed background image
The header background is transparent
I don't want my content to override my transparent header
I came up with a solution scrolling the div instead the body:
<div>
<div class="header"></div>
<div class="content"></div>
</div>
.header { position: fixed; ... }
.content { position: fixed; height: calc(100% - HEADER_HEIGHT); overflow: scroll; }
I too faced similar issue, but solved it using a simple dirty hack
1) have a white image in images folder
2) then add this css in header style
z-index:999; // to make header above the scrolling contents
background-image : url("../images/white.png"); // to hide the scrolling content
3) It is done!!
The header's z-index is set to 1000, so the z-index of the container would have to be 1001 if you want it to stack on top of the header. https://codepen.io/richiegarcia/pen/OJypzrL
#header {
margin:0 auto;
position: fixed;
width:100%;
z-index:1000;
}
#topmenu {
background-color:#0000FF;
height:24px;
filter: alpha(opacity=50);
opacity: 0.5;
}
#leftlinks {
padding: 4px;
padding-left: 10px;
float: left;
}
#rightlinks {
padding: 4px;
padding-right: 10px;
float: right;
}
#containerfixedtop {
width: 100%;
height: 20px;
}
#contentfixedtop {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height:20px;
}
#container {
position: relative;
top: 68px;
width: 100%;
height: 2000px;
overflow: auto;
z-index:1001;
}
#content {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height: 2000px;
}
I was having the same problem. I just used added z-index:10 to the .header in CSS.
I solved this problem by adding another fixed div positioned right under my header with margin-top of the size of my header.
HTML:
<div id="header">
<div id="topmenu">Home | Find Feeds | Subscriptions</div>
</div>
<div id="fixed-container">
Content...
</div>
CSS:
#fixed-container{
margin-top: header_height;
height: calc(100% - header_height);
width: 100%;
position: fixed;
overflow: auto;
}
I was facing the same problem, so the answer that tize gave helped me alot, I created a div right under my header and used some css(z-index, overflow and background), so the main element is scrollable and hid behind the transparent header:
HTML:
<header>
<h1>Hello World</h1>
</header>
<div class="inv-header"></div>
<main>Content Here...</main>
CSS:
header{
position:fixed;
background:rgba(255,255,255,80%);
top:0;
width:100%;
z-index:10;
}
.inv-header{
position:fixed;
top:0;
height:12.8%;
width:100%;
background:inherit;
}
main{
margin-top:5.9%;
padding-top:1%;
overflow:auto;
}
