HTML coding

I'd like to take this opportunity to thank HTML for making me waste my entire day on re-doing my myspace page. Why can't editing be simpler? I'm gonna have nightmares of this tonight:

body { background-colour:000000;}table, tr, td {background-colour: transparent;}table, td{ background-colour: transparent; } table table table{ background-colour: 3b3b3.; border-color:3b3b3.; border-style:solid; border-width: 2px; }

The nightmare is going to be a mere floating black background with a grey outline - 'cause that is what all that jibberish translates to.

Also... if anyone knows their html, please lemme know how I can take the transparency mode off my calendar box without screwing up the rest of my fields.
