I'm having a spot of bother with div tags. On my site, www.quib.co.uk, I have a dropdown menu in the top left corner. However, when it drops down over the main div tag in the page, the menu seems to lose its ability to perform the link-hover-color change when my mouse is overone of the options.
OK, for starters, you need to put your <div> within <body> Currently you have
In your <table>, at multiple places you have used <tr> instead of </tr>. Rectfy that error.
Probably you were using IE to test your pages. IE is very forgiving, which is why you couldn't spot much of your errors. If you check with different versions of IE, you'll find your page displayed differently, due to small errors here and there.
