CSS 100% height + header with static height; - css

I am building a layout which includes a header, which is 40 px in height. Underneath this header a SWF resides that should take up the rest of the available space.
The best solution untill now has been working with a table, giving the first row 40px height and the second row a 100% height - but these rows still add up in Internet Explorer, resulting in a scrollbar appearing for 40 extra pixels - which should not be the case.
I tried using this: http://www.456bereastreet.com/archive/200609/css_frames_v2_fullheight/ - it works fine if you have content that pushes down eventually but with a SWF with 100% in it, it will take over the whole page, or half the page (depending on putting the SWF in the content div or the SWF being the content div).
Before I resort to javascript to take care of this business I am wondering if someone else knows a better solution?

Try setting your header as static. So it floats over the main body, and set the main body to 100% height. Then give the body a 40px padding on the top.

A similar solution to forcing a footer to the bottom of a page might work
html, body{height:100%;margin:0;padding:0;}
#head{height:40px;background:blue;}
#wrapper{min-height: 100%;height: auto !important;height: 100%; margin: 0 auto -40px;background:red;}
#content{}
<div id="wrapper">
<div id="head">
</div>
<div id="content">
</div>
</div>

100% height responsive sidebar

How do i go about setting up a full height side bar using a responsive grid system, that is similar to bootstrap?
The issues I am running it to is the .main wrapper div collapses to the height of the .primarycol div.
I 'm using pull and push classes to adjust the visual layout so the .secondarycol div looks like its on the left hand side, even though it is after the .primarycol div in the code.
<div id="main" class="main content">
<div class="row">
<div id="primarycolumn" class="primarycol col12 col9-768 col3-768-push" role="main"></div>
<div id="secondary" class="secondarycol col12 col3-768 col9-768-pull col7-1024-pull" role="complementary"></div>
</div>
</div>
Normally the without the .secondarycol` class, the div would and look like this.
I have tried adding min-height:100% to the .main div and height:100% to the body tag, but that makes the main div height only ever be the height of the browser window and not the content.
Any suggestions on how I can remedy this would be really welcome.
This is the codepen of my base structure.
http://codepen.io/onebitrocket/pen/ZYQLMm/
I've added in the third column as well as some pages require one.
The column system is based on bootstraps, but i think it's an improved version:
The column classes are declared from smallest size to largest size.
I've also changed the class names to indicate the breakpoint size rather then xs,sm,md,lr etc..
Thanks
At least on chrome you need to set the height on the html tag too. Try it - http://jsfiddle.net/27kze60s/
html, body { height: 100%; }
Fixed, thanks to everyone for the suggestions
I've added the following to the css
height:100% to body
min-height:100% to .main
overflow:-y: auto to .secondarycol
I've updated the codepen - http://codepen.io/onebitrocket/pen/ZYQLMm/

Responsive height content background color

I'm using Kube CSS framework to create a demo site at www.dreametry.nl/ddfleurs . It was going well until I came across a problem with the main content background color. On the desktop the white background grows with the content, but not on a mobile device. The problems is the white background stops half way the content.
I tried using several styles, the only changes was with
.content { min-height: 650px; }
But then the background height is too much on mobiles.
Including height: 60%; to the previous code doesn't work.
This can be solved in two ways.
by giving
overflow: hidden
to class="unit-75 content"
or by clearing the div
<div class="unit-75 content" >
<!--All you HTML-->
<div style="clear: both"></div>
</div>
You can use overflow:hidden on the wrapper element (body tag, a particular div etc) to force it to adapt to the height of elements contained IF your layout uses floats.

Escape the bounds of a div container

Alright, I understand that the purpose of a DIV is to contain its inner elements - I didn't want to upset anyone by saying otherwise. However, please consider the following scenario:
My web page (which only takes up a width of 70% of the entire page) is surrounded by a container (a div). However, under my navigation bar which is at the top of the page, I would like to create w banner that takes up 100% of the width of the entire page (which means it will have to extend outside the bounds of its container as the container is only taking up 70% of the page's width).
This is the basic idea that I am trying to accomplish: http://www.petersonassociates.biz/
Does anyone have any suggestions for how I could accomplish this? I'd appreciate any help.

If you just want the background of the element to extend across the whole page this can also be achieved with negative margins.
In a nutshell (correction from comment):
.bleed {
padding-left: 3000px;
margin-left: -3000px;
padding-right: 3000px;
margin-right: -3000px;
}
That gives you horizontal scroll bars which you remove with:
body {overflow-x: hidden; }
There is a guide at http://www.sitepoint.com/css-extend-full-width-bars/.
It might be more semantic to do this with psuedo elements: http://css-tricks.com/full-browser-width-bars/
EDIT (2019):
There is a new trick to get a full bleed using this CSS utility:
width: 100vw;
margin-left: 50%;
transform: translateX(-50%);
I guess all solutions are kind of outdated.
The easiest way to escape the bounds of an element is by adding:
margin-left: calc(~"-50vw + 50%");
margin-right: calc(~"-50vw + 50%");
discussion can be found here and here. There is also a nice solution for the upcoming grid-layouts.
If I understood correctly,
style="width: 100%; position:absolute;"
should achieve what you're going for.
There are a couple of ways you could do this.
Absolute Positioning
Like others have suggested, if you give the element that you want to stretch across the page CSS properties of 100% width and absolute position, it will span the entire width of the page.
However, it will also be situated at the top of the page, probably obscuring your other content, which won't make room for your now 100% content. Absolute positioning removes the element from the document flow, so it will act as though your newly positioned content doesn't exist. Unless you're prepared to calculate exactly where your new element should be and make room for it, this is probably not the best way.
Images: you can also use a collection of images to get at what you want, but good luck updating it or making changes to the height of any part of your page, etc. Again, not great for maintainability.
Nested DIVs
This is how I would suggest you do it. Before we worry about any of the 100% width stuff, I'll first show you how to set up the 70% centered look.
<div class="header">
<div class="center">
// Header content
</div>
</div>
<div class="mainContent">
<div class="center">
// Main content
</div>
</div>
<div class="footer">
<div class="center">
// Footer content
</div>
</div>
With CSS like this:
.center {
width: 70%;
margin: 0 auto;
}
Now you have what appears to be a container around your centered content, when in reality each row of content moving down the page is made up of a containing div, with a semantic and descriptive class (like header, mainContent, etc.), with a "center" class inside of it.
With that set up, making the header appear to "break out of the container div" is as easy as:
.header {
background-color: navy;
}
And the color reaches to the edges of the page. If for some reason you want the content itself to stretch across the page, you could do:
.header .center {
width: auto;
}
And that style would override the .center style, and make the header's content extend to the edges of the page.
Good luck!
The more semantically correct way of doing this is to put your header outside of your main container, avoiding the position:absolute.
Example:
<html>
<head>
<title>A title</title>
<style type="text/css">
.main-content {
width: 70%;
margin: 0 auto;
}
</style>
</head>
<body>
<header><!-- Some header stuff --></header>
<section class="main-content"><!-- Content you already have that takes up 70% --></section>
<body>
</html>
The other method (keeping it in <section class="main-content">) is as you said, incorrect, as a div (or section) is supposed to contain elements, not have them extend out of bounds of their parent div/section. You'll also face problems in IE (I believe anything 7 or below, this might just be IE6 or less though) if your child div extends outside the parent div.

Background image and div positioning?

I have the following structure:
<div id="wrap">
<div id="container">
<div id="header">
</div> <!--close header-->
<div id="main">
… etc
I'm trying to display a background image that will show the full height of the image, but not force the page to scroll as a result of it but that will scroll with the page content.
I've placed a #bgimage div after the opening tag of the #container div and I've tried the following CSS:
position:fixed + height:100% - displays the full height of the image but doesn't scroll with the page content
position:absolute + height:100% - scrolls with the page but cuts off the image where the page content ends
position: absolute + height:1000px - displays the full image but forces the page to scroll
Any idea?
Thanks
Set the background on the body itself. CSS3 allows you to set multiple backgrounds in case you already got one. Although this doesn't work in IE8 and before.
[edit]
Since that doesn't work in your page, try to make the bgimage div a container for your page content without specifying an exact height. Set the min-height to 100%.
That way, it should size to the page content. It will always reach to the bottom of the window, and it won't force scrollbars when they're not needed. The min-height causes the div to fill the window in case the content is smaller than the window height.
Use background-attachment: fixed; it will scroll with the page.

Getting 960 grid layout to 100% height

I'm working on a layout using the 960 CSS grid layout and having some trouble getting my content div to stretch all the way to the bottom, no matter how much content there is.
I have height: 100% on both html and body tags. Usually a min-height: 100% on the content div would work but that does not seem to be the case with the 960 grid.
Any ideas?
Not sure if this answer is still needing to be answered, but I ran into the same problem today working on a wordpress template and solved the problem.
What you have to do is make a wrapper before the container_12 or container_16 that is provided by the grid. You don't need html or body equaling height: 100% at all. You don't even need a min-height on the wrapper.
Make sure that your wrapper doesn't have a height or width set, and put the clearfix on container_12 or container_16 and it should expand all the way down.
I have this working on my wordpress template.
<div id="yourwrapper">
<div class="container_12 clearfix">
<div class="grid_12">
<!-- YOUR CONTENT SHOULD BE COMPLETELY WRAPPED BY THE WRAPPER -->
</div>
</div>
</div>
