[ale] Problems with style sheet

[joh6nn]

it may be somehow related to the specificity of the rule.  try changing 
a.black to #black, and see if that registers.  if it does, then your 
permanent fix (assuming you're not going to have a.black links elsewhere 
on the page) would be to change the CSS to read td.main a.black, or 
something equivalent.

if that's not it, here's what i usually do when i've got a CSS problem 
to bang my head against:

1) validate the HTML and CSS; this'll help find typos and other trivial 
stuff that can throw things out of wack.

2) reduce it to the simplest possible test case; helps you figure out if 
it's something in your code, or if it's something in the browser.  i 
generally notice something stupid that i did at this step

3) start googling to see if there's some browser bug that this is 
related to.
