An issue with nested divs - css

Question

I'm sure there's a simple solution to this, but I've been beating my head up against it for an hour or two and not making much progress.
Basically, I've got a wrapper div (testwrap_outer) containing a secondary wrapper div (testwrap_inner) that holds together an image thumbnail div (test1), and a caption div (test2).
I need the caption div (test2) to scale height according to its content, the secondary wrapper (testwrap_inner) to contain that div and float next to any other secondary wrapper divs, and the main wrapper (testwrap_outer) to contain all of them.
I apologize for doing such a poor job explaining, so I've provided a picture to illustrate what I mean here. Here is a fiddle.

CSS
body {
background: #cccccc;
font-family: Arial, Helvetica, sans-serif;
min-width: 900px;
}
.testwrap_outer {
border: 1px solid red;
position: relative;
}
.testwrap_inner {
border: 1px solid blue;
float: left;
margin: 5px;
padding: 4px;
width: 296px;
}
.test1 {
border: 1px solid purple;
position: relative;
float: left;
opacity: 1.0;
width: 80px;
height: 80px;
overflow: hidden
}
.test1 img {
height: 100%;
}
.test1 img:hover {
opacity: 0.6;
}
.test2 {
border: 0px solid green;
position: relative;
float: left;
text-align: justify;
text-justify: inter-word;
padding: 6px;
width: 200px;
}
Any help is much appreciated.

Answer 1

Add inside testwrap_outer an empty div with clear:both style. This will tidy up the layout and make the outer div behave as a container supposed to be behave.

Answer 2

just include overflow:hidden in your class testwrap_outer, also there is no need of position:relative in your code!!
CSS:
.testwrap_outer{
border: 1px solid red;
overflow:hidden;
}
