css - why is my content showing outside the div?

Question

I have a "bubble" with content, which is working fine. Now, I want to display a count (2 lines) which should always be in the bottom right corner of that div, INSIDE it. I tried many things but for some reason it always overlaps the div and shows outside. What am I doing wrong?

<style type="text/css">
body{
background-color:#f3f3f3;
}
.commentbox{
background-color: #ffffff;
width: 200px;
border-color: #D1D1D1;
border-radius: 4px;
border-style: solid;
border-width: 1px; 
padding-bottom: 9px;
padding-left: 9px;
padding-right: 9px;
padding-top: 9px;
position:relative;
}
.count{
float:right;
text-align:right;
}
</style>

<div class="commentbox">
<div class="title">Some several lines long long long long content text goes here 
</div>
<div class="count">123<br>456</div>
</div>

Answer 1

You are floating .count so it doesn't influence it's parent container's height.

Set overflow: hidden on the parent (.commentbox) or use one of the other float containing techniques so that it does.
