Salve a tutti io ho un problemino... non sono abile con i css.
Quello che vorrei fare è ridurre al minimo il peso di questo css
C'è qualche modo in cui posso ridurlo di dimensioni a parte limare gli spazi bianchi?

Codice:
/* TOP Buttons */

#buttons {

	float: right;

	margin: 0px;

	padding: 0px;

	width: 50%;

}

ul#mainlevel-nav

	margin: 0;

	font-size: 0.9em;
