I have a div that shows some text and is absolutely positioned on a page. While it is absolutely positioned the div is just large enough to show the text it contains. When I add an inline style to that div to change it to be relatively positioned, the width of the div suddenly expands to take up 100% of the page...
I used the Chrome dev tools to toggle the relative position on/off. Turning it off causes the width to be correct, turning it back on causes the div to expand. It is an inline style so there isn't any CSS class or selector that is changing the width on me.
I experience the same issue in Firefox. Removing position: relative in Firebug causes the width to shrink back down to be just wide enough to fit the text.
If you want relative position DIV take his content width then you can give float, display:inline or display:inline-block to your DIV
could you please post the HTML and CSS, and I could have a look at it..
Meanwhile you might wanna have a look at
Position an HTML element relative to its container using CSS
and see if that could possibly help you?
to change size as content grows/shrinks use something like:
<div style="min-height:30px;max-height:300px;">
Which will mean it'll vary between 30 and 300 px depending on content
or
<div style="min-height:30px;height:auto;">
which will vary between 30px and as big as its container will allow (so forever, essentially)

I have a div, .instagram_grid which has margin-left and margin-right set to auto, is relatively positioned, and has a width which for browse sizes 900px >makes the div be centered nicely in the page.
when I have the simple structure in the context of the rest of the CSS for a single page, the no longer becomes centered at browser width >1684px. In the Fiddle that follows I only have two lines that modify the div as a whole (and one just sets the background to pink). There are no media queries present, which suggests that it is the effect of some unseen preceding div/element causing the behavior.

The behaviour is what is expected with that markup.
The element is centered, but then you use relative positioning to show it 500px to the right of where it actually would be.
The .calc-text div above the .instagram_grid div causes its parent to overflow by setting margin-left:auto while simultaneously setting left: to a negative value, which isn't valid CSS.
I have a bunch of html that is absolutely positioned and then html snippet that is supposed to show after that. But they over lap.

Everything under .drag-drop is supposed to be absolutely placed so the height and width of .drag-drop become zero. The exhibit button and the exhibit text are supposed to show after the bolded This is Drag and Drop Item. But because the height of .drag-drop is zero it shows right over the contents of .drag-drop`.
I have had this issue before, but fortunately it was easy to calculate the height of the children of .drag-drop and then I would set the height of the .drag-drop to be that using javascript. This time it is harder as it contains more children and they are not constant. How would I change my css so that the Exhibit shows below the drag drop ?
Absolute positioning removes the element from the layout, therefore the children are no longer part of the calculation of the parent's sizing. You'll need to use JS to solve this.
The best way is not to make the content absolute positioned at all. Could you make them relative positioned, or float them? You can still manipulate their position, height, width, etc., and they'd have layout so the containing div would have the correct height.
Note if you float them, you may need to add a "float breaker" at the bottom of the containing div to get it to calculate the height correctly:
....
<div>some floated content</div>
<br style="float: none;"/> // float-breaker right before containing div closes
</div>
Otherwise the previous answerer is correct, you'll need some js hackery.
I have to add a small banner at the top of a page and am having trouble with pushing the existing content down 40px so I can fit in the banner above.
The current layout has a lot of strangley positioned elements and they all keep moving out of place if I wrap the whole body area in a relative block div with a top margin.
Is there a technique that should work for this other than wrapping in a div like this?
If you do this, then you have to be careful that your CSS positioning on the divs that you want to move is not absolute. Because if it is, then they will just stay where they are. It should however, work if you add a div that encompasses everything and put a few pixels of padding on the top with CSS.
Why not just put a at the top of the page and set that div to clear:both afterwards. This should shift the rest of the page down 40px, or whatever you set the height of that div to. Of course, I'm just guessing here without looking at code and/or a sample site. Since I assume by strangely positioned you mean weird usage of position:absolute, this should allow your current setup to remain consistent.
I have a problem regarding relative positioning. I want the body to have a background color of say, blue. Initially the page should be just of height 100% (that may vary from computer to laptop, of course, hence I can't specify a fixed height in pixels), thus the entire page should appear blue. In the middle of the page is an element, that has been set to that position by relative positioning (it can't be absolute, can it, in order to expand with its content). The element can expand vertically. If the height exceeds the boundary of the page, the page also should expand, the background of the expanded portion being still blue.
Now how do I achieve this? The only solution I can think of is to use relative positioning for the background element (which is blue and should remain blue on expansion). But for that, I must set it to the available height (relatively positioned elements cannot be assigned height through percentage value, so that rules out height: 100%). But the height itself will vary depending on the browser, viewport size, etc (and I can't use Javascript!). So how do I do this?
Is the height of the element in the middle known?

The JavaScript is just for changing the height of the div in the middle.
Is there a way to make an element not contribute to parent overflow, but keep it visible? Let me clarify
There is a watermark-like logo to be applied to a page in the manner below. It is supposed to be positioned partly outside the main content (dashed blue line)
I'm not aware of the option to set an element background in such a manner that it would persist as the browser window is resized horizontally, so I've just added a <div> with the logo as its background and position:absolute with the necessary offset relative to main content container.
Previously, the page would not get a horizontal scrollbar as long as the browser was wider than W1. Now, with an additional "watermark" element added outside of the main content box, the scrollbar would appear whenever the browser is narrower than W2
Is there something obvious I'm missing? A background setting, or possibly a neat margin workaround/
Update:
I've added a rough jsfiddle to illustrate the issue
Unfortunately, just because you nested the "watermark" div and positioned it absolutely doesn't make it outside of the document. If you put it outside of the document, the page will scroll (as you see).
To me, the first solution I think of is to move the watermark outside of the "content" div and apply the watermark to its parent container. I'm guessing you haven't done that because you need it to be relative to the "content" div, but it's something to try.
Also, the reason it scrolls is because the document has been overflow. The quick fix, yet not recommended, is to use "overflow-x: hidden;" on the parent container of the "content" div.
It's harder to give you a solution since you've stripped the rest of your HTML, and some "fixes" may not be as applicable if your structure is complicated in certain ways.
Remember that the width of your elements is greater than the actual "width" it includes padding & margins, if you have padding on your div reduce the "width" by the equivalent amount.
does that make sense? if you post the actual css & html it might be easier to give you a more detailed answer
additionally could you not assign the image as the background of the actual body element and set it to centered?
I've had a play with the code and come up with a possible solution for you.
set
body{overflow-x:hidden;}
then add
#media all and (max-width: 400px)
{
body{overflow-x:auto; }
}
as soon as your screen is smaller than 400px (the width of the div) your overflow:hidden will be overridden and you'll be given you scroll bars.
at this point you may also want to reduce the width of your watermark.
