I need to have a div that's absolutely positioned and contains two child divs: one with text that goes on top, and one with a background-color that's on the bottom. Like so:
<div class="test1">
<div class="caption">Text that determines width of parent.</div>
<div class="bg"></div>
</div>
I know I can just set a background color on .test1, but I need this background to be a separate div to give me backwards-compatible (IE 7+) control over the position, opacity, width, etc. using jQuery.
With the following CSS, I can get everything to work, except that the text is behind the .bg div. I need the text on top.
<style type="text/css">
.test1 {
position: absolute;
left: 100px;
top: 100px;
}
.test1 .caption {
float: left;
white-space: nowrap;
}
.test1 .bg {
height: 50px;
background-color: #222;
}
</style>
How can I have the width of .test1 be based on the width of the text and have the .bg div be 100% width and underneath .caption? I should repeat that this needs to work in IE 7 and above.
Here's a fiddle: http://jsfiddle.net/kbp6r/
For the positioning problem, you'll have to rely on the magic of z-index
;) it is applicable to elements that have a non-static position (default is position: static
). Therefore, have you considered absolutely positioning the .bg
element, and relatively positioning the .caption
element?
.test1 .caption {
position: relative;
white-space: nowrap;
z-index: 2; /* More than .bg so it will be above */
}
.test1 .bg {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: 1; /* Less than .caption so it will be stacked underneath */
}
In order to force the .bg
element to be of the same dimension as .caption
, you can use the dirty positioning trick - when an absolutely positioned element has the following properties declared:
top: 0;
left: 0;
bottom: 0;
right: 0;
It will fill to the size of the parent container - and in this case, the size of the parent container is determined by the content in .caption
, since you have used a relative position for it (per my recommendation).
Here is a fiddle that shows how it works: http://jsfiddle.net/teddyrised/kbp6r/2/
Change your html as like below.
<div class="test1">
<div class="bg">
<div class="caption">Text that determines width of parent.</div>
</div>
</div>
