Hint: Ask somebody else.
The following conversation should help you understand how tenuously I grasp the whole xhtml situation:

sonsica (1:00:49 PM): btw it took HOURS TO GET THE PICTURES TO WORK and be xhtml validated
sonsica (1:00:57 PM): and i have no clue what that means anyway, re: xhtml validated
sistah (1:00:58 PM): i don’t even know what that means
sistah (1:00:59 PM): sorry
sistah (1:01:02 PM): oh
sistah (1:01:03 PM): laugh!
sonsica (1:01:18 PM): i just know that you get it done and it tells you if you have errors and then you fix them and it tells you, GOOD JOB~! NO ERRORS!
sonsica (1:01:20 PM): which i like
sistah (1:01:28 PM): laugh
sonsica (1:01:36 PM): laf
sonsica (1:01:41 PM): it’s true!
sistah (1:01:50 PM): that’s why it’s so funny

Sure I could look it up and understand why I did all that work. But the knowledge of a job well done is worth more than understanding why I did the job in the first place, apparently! Cause I’m not going to look it up for at least another three days.

I’ll keep you updated.

Update, 03.18.05: I made the long and grueling trek to check out the XHTML Validator FAQ, wherein I learned what I did and why. Go, me.
