Up to now I have two choices (maybe there are more outside):
Set the width of body tag to a fixed length and set the horizontal margin of the body tag to auto. It makes all contents get horizontally centered.
Create a wrapping div inside the body. Set the width of the wrapping div to a fixed length and set the horizontal margin of it to auto. It also makes any contents inside the wrapping div get centered horizontally.
I don't know, which one is better. Or if you have another alternative that you consider the best one, let me know.
A wrapper div is more flexible, because you never know when you're going to want an element to not be centered. A couple months down the line if the site requires changes you'll be happy you had a wrapper div, ends up being less work because you can have siblings of the wrapper div and do what you want with them.
With that said, if it's a fairly simplistic trivial example/site, sure go ahead and 0 auto the body element.

I have been searching for an answer to this for some time.
i want to add space to the bottom of my web page, as content sits too close to edge.
I have tied 'padding-bottom' in wrapper tag, in body tag and in style tag.. not working.
any help on this appreciated..
thanks,
Keith.

you have a serious design problem.
all your elements are relatively position with top offset, that cause the wrapper and body to be actually smaller then you think. because this offset is not taken in consideration when determining the wrapper height. (so the height of the wrapper is only the sum of his children height, without the offset between them)
when you add padding-bottom to the wrapper or the body, it works (of course), but you don't see it. because your elements overlaps the wrapper..
you will be able to see that I'm right by setting overflow:hidden; to the wrapper (or inspecting your site with a tool). suddenly, half of your content disappears..
you need to remove the position:relative; from your elements, and use margin-top instead of top to make the desired space between the elements.
That way: the wrapper and body height will be set right, and the padding will work as you expect it.
You're positioning relatively all your elements. That's causing the padding/margin problems too. Why would you position your elements like this?
Try removing relative positioning and add top/bottom margins to your elements. The results will be the same in terms of visual effect.
It will also be much simpler adding new sound boxes, as you don't have to calculate a top positioning for each one.
Is this possible with css (I can probably manage it with javascript):
Its basically a margin: auto effect, but i want a different background for each margin, so i'm looking for divs with auto-widths on either side of the (fixed-width) center div if that makes sense. Probs better visualized:
http://jsfiddle.net/guc9V/1/
Bit of a hack but it works.
I didn't use your width value as jsFiddle would need resizing to see how it works.
This essentially tells the divs to act as table-cells, so they will fill the containing div, which acts as the table. If you didn't specify the width of the middle div, each column would be 33% wide.
I've done a bit of Googling and found a number of references to the problem I'm trying to solve, but all suggest the same solution that I can't use. The problem is that I have a sidebar floated right and some divs that need to expand to the width left over from the sidebar, but then expand to the full width when the sidebar is no longer preventing them from doing so.
The jsfiddle is here: http://jsfiddle.net/qdk3n/
The solution found elsewhere is to apply overflow: hidden; to the .left items. This achieves exactly the effect I want: divs that share horizontal space with the sidebar only expand as far as the sidebar, but additional divs expand to the full allowed width. Unfortunately, there will be an absolutely positioned item inside the left divs that exceeds the size of the div and will get cropped if I apply overflow: hidden;, so I can't use that. Is there any way to accomplish what I'm trying to do without using overflow: hidden;?
Note: I don't know the size of either the sidebar or any of the left divs prior to page render time, and I cannot use Javascript in any way, shape, or form (since this is meant to work for users with JS disabled). The only dimension I can set in all of this is the width of the sidebar; the divs need to be fluid and I can't arbitrarily choose some number of them to only extend part of the way.
Also note: I've seen this: Div stretch then wrap around other floated div. It is exactly what I'm trying to do, but the only real solution is the overflow: hidden; property, and I can't use that.
Unless i missed something, i don't think it is possible to achieve exactly what you ask for.
The reason overflow: hidden; changes the behavior of the (display: block;) elements is something called "Block Formatting Context", which you can read about here;
https://developer.mozilla.org/en/CSS/block_formatting_context
http://www.communitymx.com/content/article.cfm?cid=6BC9D
Technically, you can keep the elements display: block; and have them respect the floated sidebar, by floating your left divs as well, but this will unlikely have the effect you want.
However, any inline content inside your left divs are going to respect the floated sidebar, so i don't really see the need for the divs to behave like you describe (maybe elaborate on your reasons behind it to get more constructive feedback).
I have this code: http://jsfiddle.net/5RbrL/
As you can see, the text doesn't go over the .box div. I would like to achieve the same, but the .box div should be attached to the bottom of the container.
First thing I tried was setting the container's positioning context to relative and making .box absolute, but this takes it out of the document's flow and text is placed underneath .box, which is exactly what I don't want to happen.
I do not know the height of the container, as it will depend on the amount of text inside it.
Is there any way to make the text fill the entire container, but leave the bottom right square empty (for a background graphic)?
[EDIT]
I apologise for not phrasing my question clearly: I would like the text to wrap around the .box.
Unfortunately what you ask can't be done with pure CSS.
You need a specific height to be able to float/position elements in this manner.
You could get around it be adding more elements, but this isn't preferable as then you'd have to invent some way to spread the last parts of text over to the empty element.
Well you could fake it by adding another element and somehow injecting the last lines of text into it.
Other than that, without a specific height I am not sure there is a real way to do it. HTML should come up with some kind of pathing system :D
__
After some thinking and experimentation I have an easier solution, just include the element within the text (inside the <p>.)
Have you tried moving the image div to the bottom of the container (underneath your text) and then clearing the container with either a clear div or overflow:hidden? http://jsfiddle.net/5RbrL/14/
What exactly do you want to do?
if do you want the box in the bottom, you can put an overflow hidden in the container, and then move the .box to the bottom > something like this >
http://jsfiddle.net/3v2mr/
or the structure can't changes?
Basically I have a parent div with height and width and overflow:hidden and then within that some more divs with it.
We are dealing with fluid content and some of the divs go over the corners so get hidden.
But one is half and half.
Is there a way to make that completely hidden?
CSS would be best.
I don't think you can know if a child from an overflow:hidden parent is in the hidden or visible section without using Javascript (I might be wrong here).
What I suggest is that you set all the child divs to a fixed dimension d and set the parent div to a multiple of d so every child is either completely visible of not.
This solution won't work if you fill your divs with different-length content
If I understand your post, you have a wrapping div that has overflow:hidden and you want to make any child element hidden unless it can be completely displayed within the wrapping div.
There may be a better way to do it, but I would use a CSS media query. If you're unsure of how they work this is a good place to start:
http://css-tricks.com/resolution-specific-stylesheets/
Using this method, you could determine how many blocks of each type should be displayed on any given set of resolutions. I'd be interested in seeing how it goes, or if you end up using a different approach. Best of luck!
