Blocks side-by-side with the same height - css

Question

OK, what I need is fairly simple, though it's one of those things that I've never managed to get my head around when using CSS. So, here I am...
I'm using a custom template, built around Twitter Bootstrap.
This template features a section (declared as span6 row), containing small blocks (declared as span3). In the end, the sub-blocks form rows (2 blocks per row).
Here's a visual example :
The result is ok, though I'd still need one thing :
HOW do I make sure that 2 adjacent blocks have the exact same height? (e.g. The 1st block - "Some title here" - and the 2nd block - "Awesome work" - white rectangles being of the exact same height, no matter what the contents are... (much like the 2 last blocks)).
Any ideas?
P.S.
Please let me know, in case you need to know anything else about the "inner" structure.
I'm pretty sure it may have to do with "clear" fixes, etc - but to be honest I've never actually understood the... magic behind the trick... :(

Answer 1

Try the following:
1) Assigning parent div with "display:table" and child div's with "display:table-cell" like:
CSS:
.parent-div{
border: 1px solid grey;
display: table;
float: none;
}
.child div{
border: 1px solid grey;
min-height: 100%;
height: 100%;
display: table-cell;
float: none;
}
HTML:
<div class="span6 parent-div">
<div class="row">
<div class="span3 child-div">
......
</div>
<div class="span3 child-div">
......
</div>
</div>
2) You can also use "EqualHeights jQuery Plugin":
Include it your head by adding
<script language="javascript" type="text/javascript" src="jquery.equalheights.js"></script>
And call the function on your .parent-div as:
$('.parent-div').equalHeights();
For detailed usage and limitations, whether it is suitable for your website first read this and proceed.

Set a min-width. So in your css have:
#whatevertheboxitscalled { min-width:100px; }
Obviously it doesn't have to be 100px, but whatever size fits best.
