Collapsing? An empty element with a height of auto (and no padding or other properties, etc) will always seem invisible (the height will be computed as 0). I'm guessing that's what you're talking about."height: 100px;" or "min-height: 100px;"

I have a right and left div each has min-width:300px;. Between them is a center div defined by: <div style="text-align:center;overflow:hidden;">.the center div is centered if the right and left divs are empty of if they both contain something. However, if the the right div is empty and left one has something in it ( or the right one is empty and the left one has something, the empty div collapses. How do I keep it from collapsing when it's empty?As in:

<div style="width:890px; margin: 0 auto;">    <div id="ldiv2">       <div style="float:right;display:inline;"> here </div>      </div>    <div id="rdiv2">    </div>  <div style="text-align:center;overflow:hidden;">      <h3 style="width:195px; margin: 0 auto;margin-top:10px;margin-bottom:40px;">join here for best prices</h3>      <form name="input" action="parse_join.php" method="post">          <div id="div1"><input id="input1" name="fn" type="text" value="your firstname goes here" onfocus="this.value='';" /></div>      </form>   </div></div>

Like I said, "min-height: 100px;". It sounds like you already give it a width.
