in css # is used to refer to an "id" of an element.

and . is used for referring to a class.

<div class="text_wrapper">
<div id="text">
....
</div>
</div>

note:remember, ids are usually used in inner elements...but then again, its up to the situation....

with # selector you can select an element by it's id. it means you can only select one element in the document.
the '.' selector is for select a whole class. it can be one or more elements.
