I've got a HTML / CSS question about growing a div to fit the screen when filled with other divs.
Here's my structure which is inside my "main" div:
I've got 3 divs inside of a container div, with the last div inside the container having an overflow:auto; property (as it has scrollable content). The whole container div is floated left.
How can I get the last interior div to expand with the screen resolution? The problem here seems to be that my container div has no real "size" so when I set it to height: 100%; nothing really happens. Of course this means that if I assign it an actual size, then it won't grow to the resolution..
What should I do?
Have you looked up CSS3 media queries? Here's a tutorial and demo.

I have a div main container that contained 3 others div containers.
I want that the 3 child div stay center and always on the same height (at the top of the parent div).
My problem is when I resize the window browser, the child div go under the other. I don't want this.
I also add a css condition for under 768px. In this case, I want that the child div go under the others.
Here a fiddle example: http://fiddle.jshell.net/mCXWs/
In this fiddle the child the blue div go under the green and the yellow under the blue for a window browser above 768px. I don't want this result. I want the stay at the same height (top: 0;)
I don't know what to do ...
Sorry for English, I'm French
3 blocks always of the same height? Use CSS table layout: display: table and display: table-cell (IE8+)
a (block displayed as a) "cell" will never go below another "cell", problem already solved (edit: in the same implicit row)
centered horizontally? Use margin: 0 auto; on container
at the top of parent div? Use vertical-align: top.
under 768px (in MQ #-rule), just override table(-cell) by display: block and divs will behave like default div, going one under another. You also have to override min/max-height, maybe.
avoid overflow: hidden and position: relative (well, with tables...) as long as you can
Working example: http://fiddle.jshell.net/EEEjg/1/
I'm developing a mobile website that integrates horizontal swiping. Unfortunately this has created a headache when trying to get the rest of my website layout to work.
http://jsfiddle.net/N7eWS/4/ - try resizing your browser window fairly small and you'll see the #footer (red) halfway down the content inside #wrapper (green). This appears to be todo with setting height:100% on most of the elements and then the absolute positioning applied to the horizontal swiping div (swipeview-masterpage-1).
I want it so that #wrapper expands to the height of the content, the #footer sits underneath #wrapper and is always off the bottom of the screen (you should have to scroll to see it).
Is there anyway I can make this work without touching (or perhaps making minor changes to) the swipeview divs? Any ideas would be appreciated!
One of the problems is the position: absolute on #swipeview-masterpage-1 and then another absolute on the parent. Parent absolute elements will not expand to the height of any absolutely positioned children (example).
You also have a random <span> in the mix, which is an inline element and will have a height of 0 anyway. Remove that to make things clearer.
Now to why your footer is appearing in a strange way. Your #wrapper will always be 100% of the parent height, your footer will always exist at 100px (header) + 100%. Disable the min-height property and you will see the wrapper collapse, and the footer sit at 100px. That's why the #wrapper content overlaps the footer.
I have a parent div that has a bunch of child divs inside it. I want the child divs to be horizontally laid out beside each other. Which means the parent div can not be set to an exact width amount as the image amount will change all the time. So I presumed setting the parent div to width:100% then the children div items inside it I would float:left.
It will only work if I give the parent div a set width that matches the width of all the child divs inside it. Is there a way to have it 100% and lay the children divs out side by side horizontally inside the parent.
Take a look at this example fiddle - is this what you want?
Essentially, you just need to declare the following on your wrapper div, thats all
#wrapper{
white-space:nowrap;
overflow:hidden; /* whatever suits you - could be scroll as well*/
}
you don't need to float the images, as they are no block-level elements per default.
So most of this site so far uses auto centering (the container and nav have margin-left/right:auto) and things seem to go all well and dandy except for the footer.
When I resize the size of the window everything is filled nicely except when I scroll horizontally the footer seems to be cut off on the right side.I've read that this may be a browser bug. Though it occurs in IE and chrome and firefox so it could just be sloppy coding (I am a big newb).
Here is the css:
#footer {
background-image:url(../Images/footer_bg.jpg);
color: white;
height:300px;
padding-top:20px;
}
/*I have 4 headings with Ps that I want to display horizontally side by side*/
#footerContent{
min-width:1000px;
}
/*So I tried floating <li> inside <ul> and limiting its width, which worked fine */
#footerContent ul{
width:1000px;
margin-left:auto;
margin-right:auto;
}
#footerContent li {float:left; width:250px; }
Just to reiterate it works fine when the browser is full screened or resized. But after you resize and you use the horizantal scrollbar to scroll all the way right then the background image is cut off.
I've tried width:100%, min-width, width:1000px; but none of those seemed to work.

Regarding your comment about Stackoverflow being similar
(at least as of 4-29-2012)
The issue on stackoverflow seems to be that the footer contains another div element, footerwrap, that has a width: 960px set to it, but footer itself has no width setting. A div is basically designed to simply "group" block level content. It is a common misconception that a div expands with it's content. Actually, a div expands to its parent if an explicit width is set on a parent. If there is none, then it fits the browser window. This is what you (and stackoverflow) is experiencing.
To get the div to relate to the content width, you must either:
Explicitly set the width or min-width of the container. So, if stackoverflow set a min-width: 990px (the 960px of the footerwrap + the padding of 15px on each side) on the footer that wraps footerwrap, then its problem is solved.
Set the container div to float, as a floated element wraps its content.
Take a look at this example fiddle. Note the first two div's experience the same issue you are seeing. If you shrink or expand the size of the iframe window in the fiddle, the first two div's will contract or enlarge with it, but still leave blank space on the horizontal scroll. The third and fourth div's have had my fixes above applied. The fifth div is to show the fact that the inner div, if not defined in width, will expand to the width of a container that has an explicit width set.
As a side note, it may work (I have not tested in many browsers, but FF 11 worked) to actually just add a float: left to the body element in those cases where the body does not have a set width. As this example shows, it seems to be effective in causing the first two div's to behave just like the 3rd and 4th divs.
I hope this helps.
Original Answer
It is a little unclear what can be done because there is some information lacking. Here are some things to look for:
Is your background-image wide enough (or can it / should it have a background-repeat: repeat-x applied to make it wider if needed)?
Does your footer width (1000px) match your upper content width? If footer is constrained narrower than what the upper content area (or header, etc.) is allowed to be, then it's background will not align.
That's the best I can do without seeing more of your html and css for the page, and not knowing the size of the image and your intention for how it is to function.
I've got a container that's set to a max-width:780px and height is undeclared. Inside the container, there's an image slideshow. Everything on the page is responsive, so as the width decreases, the image (who's width is set to 100%) adjust's the heights container.
The slideshow change's the images to display:static; and position:absolute; which no longer "holds open" the container because it's not seen as content of the container
Is there any creative solution out there to take the height of a child element that's absolutely positioned?
Example below has NO height declared on the main container.. nothing's holding it open.

Thank you!
Are the images all the same dimensions? If yes, you can use a percentage padding-top on the element that contains the images.
So if your images are all, say, 760px wide by 500px tall, that's 500/760 = .65789
Which as percentage would translate into something like:
#main {
position: relative;
max-width: 760px;
padding-top: 65.789%;
}
The reason this works is because with padding if it's set with a percentage, it is calculated as a percentage of the width. As the element shrinks in width, the height will shrink proportionately and the box will remain in the same ratio of width to height. The images, positioned absolutely, won't be adding to the height of the box.
This'll work as long as your images are all the same aspect ratio and you're not expecting that ratio to change. If you'll be using a lot of random images, this isn't for you.
I recently had a similar problem with an image that I needed to absolute position at the top of a Zurb Foundation templated page in order to pull it out of the flow and reset its dimensions (Image had to stretch to edges of wrapper, instead be enclosed by its parent .row padding). However, of course, this meant that all the fluid responsive elements below it popped right up over the top of the image. Setting a margin-top or positioning the sibling elements below meant a rigid top space that didn't resize with the width of the browser.
To get around it, I placed a duplicate of the image right after the absolute positioned image and set its visibility: hidden; I had to add a little bit of extra margin bottom to make up for the difference in height, but the end result is everything on the page flowing exactly to the height of the image in use.
I've also used the padding trick described by unexplainedBacn above, and it's a great trick as well. It takes a little bit of math, but I voted that answer up. Great solution.
I think you'd better change your approach. For sliders, the best practices is to float child elements of the container, and also use one of the known techniques to prevent parent's great collapse. So, I suggest that you remove the position: absolute CSS rule from images and float them inside your <div id='main'>, then use any of these methods to force it to encompass it's children:
div#main {overflow: hidden;}
div#main:after {content: ''; display: block; clear: both; visibility: hidden;}
Add a <div style='clear: both;'> to the end of your main div container.
Remove the absolute position. I would avoid inline styling as well.
