Child Div Not Expanding To Parent Div
Solution 1:
height doesn't behave the way you seem to be anticipating. When you specify height: 100% that percentage is calculated by looking up the DOM for the first parent of said element with a height specified that has absolute or relative positioning.
You can cheat when it comes to the body tag, so if you had something like this:
<body><divstyle="height: 100%"></div></body>Some browsers/versions will behave the way you expect by taking up the total height of the page. But it won't work when you go any deeper than that.
Here is the approach I use to strech a div to the bottom of the page, it involves absolute positioning (nice thing about this one is that it is pretty cross-browser compliant and doesn't require javascript to pull it off):
<divid="parent"><divid="childNorm"></div><divid="childStrech"></div></div>#parent
{
position:absolute;width:1000px;bottom:0;top:0;margin:auto;background-color:black;
}
#childNorm
{
position:absolute;width:1000px;top:0;height:50px;background-color:blue;color:white;
}
#childStrech
{
position:absolute;width:1000px;top:50px;bottom:0;background-color:red;color:white;
}
Here is a Jsfiddle for demo: http://jsfiddle.net/t7ZpX/
The trick:
When you specify absolute positioning and then put in bottom: 0; that causes the element to stretch to the bottom of the page; You just have to worry about positioning the elements as a trade off.
Solution 2:
Yes, this is one of the annoying things in css. min-height is not considered a "height" for purposes of calculating height. See http://jsfiddle.net/3raLu/3/. You need to have height: 100% on the parent div to make the child full height. Or, if you can have it be absolutely positioned, then this works: http://jsfiddle.net/3raLu/6/.
