'#' is for 'id', '.' is for 'class'.  'id's are supposed to be unique on a page because they are also used by javascript.  'class' is a general style that can be applied to many elements.  Tutorial here: http://www.w3schools.com/css/default.asp

"ul li" would apply to any "li" within any "ul" regardless of ID or CLASS assigned to them.  Getting more specific, "ul li.level2" would apply to any "li" within a "ul" only if that "li" has a class of "level2".  Remember that these will add to each other, not replace each other.

Like so:
<ul>
 <li>This gets the style from "ul li" only</li>
 <li class="level2">This gets the style from both, because it is an li AND it is an li.level2.  Because there is overlap in the styles, this li will have list-style: none, font-weight: normal, padding-top:.5em, margin-left:-1em and font-size: .9em</li>
</ul>
