how i found mine was going on google and typing "windows93 myspace css pastebin" and finding some layouts that users post on their blogs via pastebin. use w3schools.com to further edit your layout to your liking. they really help and lay everything down easily!
i had little knowledge and went digging for hours but that's what i essentially did.
type CTRL+F to find key words in the CSS you pasted to find keywords so you can edit it easier.
w3schools.com helps with RBG/RGBA, HEX, HSL for color coding and much more
hope this helps and also encourages u to learn at the same time :)
coolcoolcool some people dont edit and it looks sily
Many of those are made on pastebin without the creators knowledge It really sucks
