Several builds back, forms started treating the <div> tag a bit differently. Prior, they used to expand to the full width of the separator, now they expand only to the width of the contained text. I remember there was a thread on this and I can't find it now. But I recall there was an adjustment to make that returned the previous behavior. Here is the HTML. I just want the box area to maximize within its container.
<!DOCTYPE html>
<html>
<head>
<style>
#section {
width:auto;
background-color:#FFFFEC;
float:left;
padding:10px;
border-style: solid;
border-color:#600000;
border-width: 1px;
font-size:12px
font-family:verdana;
color:#600000;
}
</style>
<div id="section">
My text here...
<br>
</div>
