Css header problem - css

I have a header class which has a background and a header-center class which provides the nav content for the header. My problem is that if the window is smaller than the header-center width, the header background doesn't span the entire top when you scroll over. Stackoverflow seems to have the same problem, try resizing it and you'll see what I mean - they gray background doesn't expand over to the search box. How would I go about fixing this?
Thanks!

if the background is inside a container with a width of 100% and any parent container, including the <body> or <html> don't have a width set in the CSS then you will experience this behaviour. as 100% will be 100% of the browser viewport. Change this to a fixed width and it should stretch to fill the fixed width.

What you need to do is set a display: inline-block on your body tag. If you do this to stack-overflow's site. It fixes the problem.
This method is called "shrink-to-fit".
Here's a fiddle with the problem. DEMO
As you can see when you scroll the div doesn't expand the width of the whole screen anymore.
and here's a fiddle without the problem. DEMO
This has been answered similarly elsewhere by user473598 here How to make div not larger than its contents? you don't technically need the element to be a span though. buti-oxa's answer is worth noting as well as it notes that using this method is some what costly as it means formatting the element at least twice. Since it's being applied to the body it doesn't seem like that bad of a deal in your situation.

div doesn't stretch 100% width of a page if window width narrower then the rest of the content

If I resize browser window (Newest Chrome in my case) so it gets horizontal scrollbar then the header div gets "cut off". In that case scrolling to right reveals some empty space. This is because the main content other then header have fixed width.
But the header div has 100% width and div is a block element by default also so it should stretch by itself to the 100% of the page width. Why it is not doing so? Shouldn't it be the default behavior? And why StackOverflow team didn't fix it?
The problem I found on many pages, including StackOverflow:
So I've been googling, even found a solution for a problem but not satisfactory enough. The solution is to set the min-width property to the width of that 's content. But isn't there a better solution?
I'm searching for a better solution, if any? Also I'm searching for an reasonable explanation why div's default behavior to stretch 100% of the width doesn't apply here?
You see a white space because, somewhere on the page, most likely under the header element, there is an element which is bigger than 100% – that's why you see the horizontal scrollbar.
The header infact is 100%, which means it's shorter than the full width of the document - therefore the white space.
To debug, I usually open the inspector and start from the bottom to the top and delete the sibling of the header, one by one, till I get to the point where everything is no more white space. At that point you know the problem is with the last element you just deleted. Try to look for errors in that particular element.
The "cut-off" div has a width of 100% of the visible area, so everything is ok.
The Problem is, that the content is overflowing and you are now able to scroll to the 120% width.
To fix this behavior und stretch your "cut-off" div always over the full width of the page, you can apply some css:
position: absolute;
left: 0;
right: 0;
Inspect the body element and you'll see that it only extends as far as the viewport. The topbar-wrapper is 980px fixed width, and its parent with the black background, topbar, is 100% (of body). topbar also needs a width of 980px, or the body element needs min-width: 980px...here on the StackOverflow site (looks like you found a bug)
This is a problem I often found on builds I was reviewing from freelancers, where they forget to shrink their browser down. The full-width sections usually need min-widths, if the site isn't fluid and there are fixed-width elements.

Background Image appears to overflow container

I'm using Firebug to work on my CSS.
It shows the HTML, Body, and inner container all at 620px height. I assume my window is around 640px high.
Using firebug I can clearly see that all the elements end just short of the full height of the window, however the body bg-image appears to take up the whole window height, which is beyond the size of it's relative container.
How/Why is this?
Note: It is a Drupal site using normalize.css as a reset. When I talk about height there is no padding or margins on the content.
I've pushed to test, see here - http://mermaidriverpools.rickdonohoe.co.uk/
Ok, looking at your page, I'm as annoyed as you. But I think I have found why this is happening.
In this fiddle, you can see that the background properties (color, image...) extends all over the page IF it's specifically ON the body tag. It doesn't matter how big the body is (It's a 1x1 box in the fiddle).
It must be a browser behaviour. This doesn't change the actual size of the body. It will follow the normal rules (size is the same than content, a specific size if it's set or the same as the parent if inherit is set).
But in this other one (setting the background-color to an inner div with fixed dimensions) the background color doesn't extend all over the page.
Try to create a wrapper as a children of your body and place body styles on it.
<body>
<div class="all your body classes here">
</div>
</body>
if you use firefox browser you can press
ctrl+Shift+m

CSS Container Height

I have a layout that should have a sidebar on the right hand side of the content area.
The sidebar should display 100% height of its container (#content), but for an unknown reason this content area doesn't have any height, therefore the sidebar isn't appearing.
Any help is appreciated.
Thanks in advance,
Tom
Here's my code:
http://jsfiddle.net/tomperkins/G4f6u/
You are using height: 100% for all elements surrounding it, so it is inheriting the size from the html element. As it doesn't have any size specified, neither does any of the children relying on it.
Use this to make the html and body element fill the window:
html, body { height: 100%; }
I made a few changes dealing with the positioning of the sidebar - which I changed to absolute and added a min-height so that if the contents of it were empty it would still be visible.

Not sure if this is what you were looking for - but it might help.
Set static height on your .content (in px) and you will see the sidebar
Here is an answer from a layman: The problem is that you've got two child <div>s which are both floated, meaning they are outside the regular flow of the document. This causes them to be excluded from the height calculations of their parent, in this case, the <div> with class "content".
You may fix this by adding a <div> after those two floats with style "clear:both" (I believe). This is not the "best" way to fix this particular problem, as it is adding non-semantic markup to your page, but it is fairly easy to understand and implement. Cheers!
Edit: see Container div ignores height of floated elements and then follow the link in the answer to read more.

Absolutely positioned div with width 100% is only as wide as the original window size

I have an absolutely positioned div that has a width of 100% with a background image tiling horizontally. When the browser is shrunk to the point that the width of the browser is less than the page, the remaining right portion of the div's background color is truncated.
Is there a better approach or a hack to resolve this?
Here's the example: link with the div in question being the menu.
Edit: to clarify, reduce the size of your browser so that the full width of the page (960px) requires a scroll-bar. At this point, 100% of the "page", or the viewable area, is actually less than 100% of the content. When this occurs, the menu's background doesn't span the remaining content that would require scrolling to the right to see.
This issue is present in ie7, ie8, and firefox 3.5. I haven't tested the other browsers but I can only assume that this happens there as well.
Thanks
Add:
min-width: 960px;
to the menu div selector. Fixes it for me.
With regards to the actual code structure, and as someone pointed out (but promptly deleted their post), perhaps structure your elements in a more logical layout. There's no reason to have the menu as the bottom child element (as far as I could tell anyway)
It's a more linear, free flowing code structure, rather then a spaghetti mess of containers in random orders, that it can turn into.

How do I prevent my div layers from overlapping when the browser is resized?

I've just spent the last few weeks learning how to properly design a layout. I basically thought I had everything perfect with my website layout and was ready to go about transferring the coding to Wordpress... and then I accidentally resized my web browser and discovered that all of my div layers were overlapping each other.
Here's what it looks like:
Basically it looks as though it's mainly my center content div that is being squeezed out, as well as my header image and navigation witch are in the same top div. My footer is also squeezed down as well. I've searched the internet for a solution to this problem and can't seem to find a thing.
How do I fix it so that my divs stay in place when the browser is resized?
as Walter said your CSS would be helpful. But, the main problem is that the content in the div is overflowing to other divs because the the content's div cannot contain all the content.
In your css, try setting the div's overflow property to either auto (shows scrolls bars) or hidden (to just hide the content if it goes outside's the div)
e.g.
overflow:auto;
or
overflow:hidden;
Express your widths and font-sizes in ems.
Here's a good calculator:
http://riddle.pl/emcalc/
Percentages will work, too.
Check the css in stackoverflow, and try resizing the zoom level in your browser here - you'll see everything resizes nicely at any zoom level.
I figured it out. Turns out that the width of my center content margin was dictated by margins instead of just a direct width (ie. 500px). So whenever the page was resized, the margins on the sides of the browser tried to stay as they were, thus making the entire column smaller. I just had to get rid of the margins and specify where I wanted the column to sit on the page and just justify a width for it.
you can also try the min-width. i am assuming the center div is fluid and sidebars are fixed-width.
Can you post some of your CSS?
The simplest way is to give all of your columns relatively sane width settings so that the size of the browser window doesn't affect the size of your layout. Getting fluid-width column(s) to behave is more complex and depends more on the specifics of your layout.
Check out the min-width property. Another option is applying another stylesheet when the viewport width is below x pixels with CSS3 Media Queries like so:
#media all and (max-width: 30em) {
/* Alternative narrow styles */
}
or so:
<link media="all and (max-width: 30em)"
rel="stylesheet" href="narrow.css" />
CSS3 Media Queries are still not widely supported, so you might want to look into a solution that applies the "narrow" style sheet with JavaScript through the window.onresize event. I'd recommend jQuery for such a solution.
I Had the same problem if you have a width and height in your DIV Container it wont change except the width unless you put a min-width. The problem I had was when I would make the browser window the divs would like go to the next line
so what I did was in the container I set a height and width. Before I didn't set a height I let the divs determine the heights.
