I code in Opera and test in FF and Chrome. Then I close my eyes, cross my fingers, and fire up the site in IE. This time, the gremlins from Redmond had a good time in my header.
#wrapper {zoom:1.0}/* layout disappears without this*/
.slugline {
top: 1em;
line-height:1.1;/* need line-height or IE cuts text off */
}
form#search{width:auto}/* IE thinks its too wide so use auto width */
#navgrn{clear:both}/* clear the nav to start on a new line */
.headerlink{float:left}
.headinner{float:left}/* floats must come first */
Then add a div to wrap and float that block like this:
<div id="wrapper">
<div id="header">
<h1><b>NeuroNexus</b></h1>
[B]<div class="headinner">[/B]
<a class="headerlink" href="index.html"><img class="imgposlogo" src="http://www.iraqtimeline.com/nn/images/logo/3dnpilogo.png" alt="NeuroNexus logo"></a>
<h2 class="slugline">NeuroNexus</h2>
<p class="subslug">the educational and research arm of the <a href="http://www.neurosci.us/" title="Advanced Neuroscience Institute" class="green">advanced neuroscience institute</a></p>
[B] </div>[/B]
<form method="get" action="http://www.google.com/search" id="search">
