Why doesn't following code work correctly in FireFox 3.6? I have tested in IE7, IE8, and Chrome with out any issues. Issue: The first block hover link (the table's 3rd row) doesn't apply the same style/effect as the following below it. Notes: I am trying to create my own table framework. This project is something I am doing to learn more about CSS. Before I started, I thought I knew a lot about CSS. However, to my surprise I was wrong. Who knew? Moving on... As side note, I do not want to take the time to support IE6. So, if you see a problem related IE6, please don't waste your time telling. One another side note, the following style script and HTML listed when this question is strip-down/bare-bone of the complete CSS/HTML. It should be enough to assist me.
