 <p>I don't think I've ever given a height to a tr, it just becomes as tall as the td within.</p> <p>Also, you're defining a tr height of 192, but the td is 194, taking into account for the 2px border.</p> <pre><code>tr.banner { height:192px; max-height:192px; } td.banner { height:192px; max-height:192px; border-bottom:2px solid black; } </code></pre>
