Sorry, userscripts (js) or does your style sheet (css)?
For simple styles enough, as already said, htmlbook.ru. If you want a deeper understanding of the material, I recommend:
E. Meyer "CSS Cascading style sheet" (ed. O'reilly)
C. Musciano and B. Kennedy "HTML and XHTML" (ed. O'reilly) — here are some chapters cover CSS
