Made an image for better understanding of the problem.
Need code for .bgimage and .content div
Is this even possible for crossbrowser css (IE7+ and other major browsers) without any scripting?
It was actually a bit longer than expected, but I got your picture in real life. Don't ask again any questions here without doing more research first and writing some actual code.
Here is a demo
The code
HTML:
<body>
<div id = "header">
</div>
<div id = "bgimage">
</div>
<div id = "content">
</div>
<span class = "clear"></span>
<div id = "footer">
</div>
</body>
CSS:
*
{
margin: 0;
padding: 0;
}
body
{
width: 960px;
margin-left: auto;
margin-right: auto;
}
#header
{
width: 100%;
height: 200px;
background-color: purple;
}
#bgimage
{
position: absolute;
top: 200px;
left: 0px;
right: 50%;
height: 600px;
background-color: green;
}
#content
{
position: relative;
width: 700px;
height: 600px;
float: right;
z-index: 2;
background-color: blue;
}
.clear
{
clear: both;
}
#footer
{
position: relative;
top: 600px;
width: 100%;
height: 200px;
background-color: red;
}
Note: I haven't optimized the CSS, there's some work that could be done there.

I have a problem with getting the height of my vertical menubar the same as the rest of the page.
So I have it like this
<div id="header">Site title etc</div>
<div id="pagecontent">
<div id="menubar">Menu buttons<div>
<div id="pageinnercontent">Contents of the page</div>
</div>
With this CSS:
html {
min-height: 100%;
}
body {
min-height: 100%;
}
#pagecontent{
position: absolute;
width: 100%;
min-height: 100%;
}
#menubar{
height: 100%;
position: absolute;
width: 170px;
background-color: #404040;
color: white;
float: left;
bottom: 0;
}
#pageinnercontent{
width: calc(100% - 170px);
left: 170px;
position: absolute;
}
However, it is not working. When the contents of pageinnercontent is "longer" than the menu, the menu is not made longer. Please help.
Use flex and don't forget margin
Here is an example, it doesn't looks exactly well in stackoverflow context, but in standalone it's valid (with )
html {
margin:0;
height:100%;
width:100%;
}
body {
display:flex;
flex-direction:row;
height:100%;
width:100%;
}
.menu {
min-width:300px;
background-color:red;
border:solid 3px black;
min-height:100%;
}
.main {
background-color:yellow;
border:solid 3px blue;
min-height:100%;
flex:1;
}
<html>
<body>
<div class="menu">
Menu Is Here
</div>
<div class="main">
Main Is Here
</div>
</body>
</html>
For today - FLEX is the only modern layout CSS 3.0 facility to be used in Application-like layouting and for one-screen sites. Floats, grids and javascript on-resize hacks for now are old-school. Most browsers provides valid flex-*** support - Mozilla, Chrome, IE9(!), Opera - all for both PC and mobile versions.
About flexes U can see here (for start): http://css-tricks.com/snippets/css/a-guide-to-flexbox/
Just do Z-index of 2 for for the menu bar and 1 for content. That ensures that the menu bar will always be on top.
html {
height: 100%;
}
body {
height: 100%;
}
#pagecontent{
position: absolute;
width: 100%;
min-height: 100%;
z-index: 1;
background-color: red;
}
#menubar{
height: 100%;
position: absolute;
width: 170px;
background-color: #404040;
color: white;
float: left;
top: 0;
bottom: 0;
z-index: 2;
}
#pageinnercontent{
width: calc(100% - 170px);
left: 170px;
position: absolute;
}
<div id="header">Site title etc</div>
<div id="pagecontent">
<div id="menubar">Menu buttons<div>
<div id="pageinnercontent">Contents of the page</div>
</div>
Note With the current structure and CSS ensures that the menu stretches to the bottom and a higher z-index number that all other elements ensures that it is always seen.
I'm having many issues regarding the positioning of div boxes in HTML and CSS. I have got a wrapper and 2 boxes. I want one box on the left and the other on the right, however the box on the right appears under the others. Why is this? I don't want to use "top" as it messes with a few other things. What do I do?
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<title>Harry Kitchener - Home</title>
</head>
<body>
<div id="wrapper">
<div id="navbar"></div>
<div id="newsbar"></div>
</div>
</body>
</html>
#wrapper
{
position: relative;
height: 100%;
min-height: 100%;
min-width: 1000px;
background-color: #ccc;
}
#navbar
{
position: relative;
height: 100%;
width: 15%;
background-color: #A13927;
}
#newsbar
{
position: relative;
margin-left: auto;
height: 100%;
width: 15%;
background-color: #A13927;
}
FIXED:
#wrapper
{
height: 100%;
min-height: 100%;
min-width: 1000px;
background-color: #ccc;
}
#navbar
{
float: left;
height: 100%;
width: 15%;
background-color: #A13927;
}
#newsbar
{
float: right;
height: 100%;
width: 15%;
background-color: #A13927;
}
The default display for a div is: "display: block".
Blocks don't obey "width" style and span as 100%. The following elements are put below the block-displayed div.
Try adding the style to your divs as "display: inline-block" (i.e. to those divs you want to see consecutive).
EDIT: did not fully understand the question fully. BESIDES doing what i told, you can put "float: left" and "float: right" to those divs if you want them to stick to the left and right respectively.
add Float:left and float:right:
#navbar
{
position: relative;
height: 100%;
width: 15%;
background-color: #A13927;
float:left;
}
#newsbar
{
position: relative;
margin-left: auto;
height: 100%;
width: 15%;
background-color: #A13927;
float:right;
}
The answer to your question is because the elements are position relative to each other.
You have multiple "solutions":
1) float your elements. See JSFiddle
E.g.
#newsbar
{
float: right;
width: 15%;
background-color: #A13927;
}
2) Change your positioning to be fixed, but likely you want absolute. See JSFiddle
E.g.
#newsbar
{
position: absolute;
right:0;
width: 15%;
background-color: #A13927;
}
3) Other options as well (display: table-cell, et cetera)
You have a ton of solutions for this one. Here are three ways of doing it, each method will produce slightly different results. jsFiddle
HTML:
<div class="method-1">
<div class="left">
</div>
<div class="right">
</div>
</div>
<div class="method-2">
<div class="left">
</div>
<div class="right">
</div>
</div>
<div class="method-3">
<div class="left">
</div>
<div class="right">
</div>
</div>
CSS:
div div {
height: 10em;
width: 15%;
border: 1px solid red;
}
div.method-1 div {
display: inline-block;
}
div.method-2 {
height: 10em;
}
div.method-2 div {
position: absolute;
display: block;
}
div.method-2 div.right {
left: 15%;
margin-left: 1em;
}
div.method-3 {
display: table;
width: 30%;
}
div.method-3 div {
display: table-cell;
}
Here's my working example:
http://jsfiddle.net/UGhKe/2/
CSS
#body {
height: 200px;
background: black;
width: 100%;
}
.header {
position: fixed;
top: 0;
background: #369;
z-index: 1;
width: 100%;
height: 5em;
}
.content {
position: absolute;
top: 5em;
overflow: hidden;
height: 1000px;
background: #936;
z-index: 0;
width: 100%;
}
.footer {
position: fixed;
bottom: 0;
background: #396;
width: 100%;
}
.large {
font-size: 120%;
padding: 2em;
}
HTML
<div id="body">
<div class="header">
<div class="large">Header</div>
</div>
<div class="content">
Content, you should be able to see this when you scroll to top.
</div>
<div class="footer">
<div class="large">Footer</div>
</div>
</div>
I want the content to be positioned below the header when you scroll the top (but hidden when you scroll down, under header) - this works fine...
However I need to remove top: 5em and use something like "inherit the current height of the header" - is it possible without JS?
If it's really not possible without JS, then I can just use JS but I'd rather try and find a solution in pure CSS.
EDIT:
I should note that the reason I can't use top: 5em is because the header will not have a fixed height - an image (for a logo) will be used inside of the text, and that would be set to max-width: 100% so that it shrinks to right width for an iPhone and doesn't expand too much on say an iPad.
See if thats work for you. http://jsfiddle.net/UGhKe/3/
I added another div with the same height but "non-fixed" to simulate your fixed header.
HTML
<div id="body">
<div id="blockHeader"></div>
<div class="header">
<div class="large">Header</div>
</div>
<div class="content">
Content, you should be able to see this when you scroll to top.
</div>
<div class="footer">
<div class="large">Footer</div>
</div>
</div>
CSS
html, body { margin:0; padding:0; }
#blockHeader
{
width:100%;
height: 5em;
}
.content {
position: absolute;
overflow: hidden;
height: 1000px;
background: #936;
z-index: 0;
width: 100%;
}
You can do it using variables(Use SASS or LESS for that). Take a look at the pen.
CODE:
$headerContentVariable: 5em;
#body {
height: 200px;
background: black;
width: 100%;
}
.header {
position: fixed;
top: 0;
background: #369;
z-index: 1;
width: 100%;
height: $headerContentVariable;
}
.content {
position: absolute;
top: $headerContentVariable;
overflow: hidden;
height: 1000px;
background: #936;
z-index: 0;
width: 100%;
}
.footer {
position: fixed;
bottom: 0;
background: #396;
width: 100%;
}
.large {
font-size: 120%;
padding: 2em;
}
What I am trying to is have a header image centered on the top with a different color background on either side, dynamically filling the rest of the page. The structure would look like this:
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Center"></div>
<div id="Header_Right"></div>
</div>
The Header_Center is of 960px and the Header_Left and Header_Right should fill either side of the image to the edge of the page and change width as the page width changes.
I can not get the CSS to work properly.
I assume you want those 3 divs to fill each with different content, the outsides filled fluidly or multiline. Otherwise the answer could be much 1) more simple. I also assume that the center div defines the total height of the header.
Given these two assupmtions, still a few different scenarios are thinkable of which I will give 4 examples from which you can choose the best fitting solution.
The HTML is exactly yours.
The CSS looks like:
#Header_Container {
width: 100%;
position: relative;
}
#Header_Left {
position: absolute;
left: 0;
right: 50%;
margin-right: 480px;
}
#Header_Right {
position: absolute;
left: 50%;
right: 0;
margin-left: 480px;
top: 0;
}
#Header_Center {
width: 960px;
position: relative;
left: 50%;
margin-left: -480px;
}
Now, you could change behaviour of left and right with a few extra styles:
height: 100%;
overflow: hidden;
See demonstration fiddle.
1) When the sides may be partially invisible outside the browser window (in case which you would align content in de left div to the right, and vise versa), then I suggest the solution in this fiddle demo which does not require absolute positioning at all so that any content below the header is properly cleared in all circumstances.
You must fix it using padding and box model + position : relative - it can be done without HTML Change
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
And CSS ( 100px is for example )
#Header_Container{ overflow: hidden; height: 100px; }
#Header_Container *{ box-sizing: border-box; height: 100%; }
#Header_Left{ width: 50%; padding-right: 480px; }
#Header_Right{ margin-left: 50%; width: 50%; padding-left: 480px; position: relative; top: -100% };
#Header_Center{ margin: 0 auto; width: 960px; position: relative; top: -200%; }
Example is here http://jsfiddle.net/ZAALB/2/
EDITed incorrect example
If I got you right then this might be a possible solution.
#container {
width: 100%;
height: 150px;
}
#left {
position: absolute;
left: 0;
width: 50%;
height: 150px;
background-color: #FF0000;
}
#right {
position: absolute;
right: 0;
width: 50%;
height: 150px;
background-color: #0000FF;
}
#center {
position: absolute;
left: 50%;
margin-left: -480px;
width: 960px;
height: 150px;
background-color: #888888;
}
#left basically says that the element will be positioned absolute and attached to the left side with a width of 50%. Same applies to #right just for the right side.
#center positions the element absolute pushed 50% to the left and then with a negative margin of width/2 which in your case would be 480px to position it in the center.
The order of the elements in the HTML is important for this hack.
<div id="container">
<div id="left"></div>
<div id="right"></div>
<div id="center"></div>
</div>
The #center DIV must be the last element if you don't want to work with z-indexes.
Here's a fiddle to test it.
HTML:
<div id="Header_Container">
<div class="Header_Side" id="Header_Left"></div>
<div class="Header_Side" id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
CSS:
#Header_Container {
position: relative;
width: 100%;
}
#Header_Container > div {
height: 158px; /* height of the image */
}
.Header_Side {
position: absolute;
width: 50%;
}
#Header_Left {
left: 0;
background-color: blue;
}
#Header_Right {
left: 50%;
background-color: green;
}
#Header_Center {
position: relative;
width: 158px; /* width of the image */
margin: 0 auto;
background-image: url('...');
}
Also see this example.
This works, but you need to change your HTML: http://jsfiddle.net/gG7r7/1/
HTML
<div id="header_background_container">
<div id="header_left"></div>
<div id="header_right"></div>
</div>
<div id="header_content_container">
<div id="header_content"><p>Content goes here</p></div>
</div>
CSS
#header_content_container {
position:absolute;
z-index:1;
width: 100%;
height: 100%;
}
#header_content {
width: 960px;
margin: 0 auto;
background: red;
height: 100%;
}
#header_left {
background: white;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
#header_right {
background: black;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
I'm working on a prototype of a website here:
http://www.paulgrantdesign.com/valcomp/index.php
I have a div in the middle that is set to stick in the middle. It's got a given height, so in the css I did
#middle {
height: 225px;
width: 100%;
background-color: #56a6c4;
position: absolute;
top: 50%;
margin-top: -112px;
z-index: 100;
}
It sits in the middle, as required. But when the window gets too small, I don't want it to cover what's above it. Can I set it so that there's always a minimum amount of distance between the top of the window and the top of this div?
May be you can use media query for this like this:
#media only screen
and (min-width : 1000px) {
#middle {
color:red;
}
}

put position:relative on the body.that s a first step. I m trying..hold on..
and bottom--position:absolute. It works! yeah!
I fixed your problem by changing your html like this:
<div id="container">
<div id="top">
<div id="topcontent">
<p id="mobile">Mobile data collection</p>
<p id="slogan">Collect. Send. That's it.</p>
</div>
</div>
<div id="middle"></div>
</div>
Then changing your css like this:
#container{
width: 100%;
position: absolute;
min-height: 350px;
bottom: 20%;
top: 0;
}
#top {
width: 825px;
min-height: 250px;
display: block;
position: absolute;
left: 50%;
height: 50%;
margin-left: -412px;
overflow: auto;
bottom: 250px;
}
#topcontent {
width: 100%;
position: absolute;
bottom: 0;
}
...
#middle {
height: 225px;
width: 100%;
background-color: #56a6c4;
position: absolute;
bottom: 0;
margin-top: -112px;
z-index: 100;
}
It might need some tweaking to get it exactly how you want it; especially with the #bottom div
You need to add the attribute z-index to the elements #top and #bottom, and let them less than the z-index of #middle.
