Hi,

I'm new to CSS and just wondering why some selectors start with a dot and some with a hash and some with nothing?

EG:

.center table
text-align: left;
}

#contentBottom {
background:white url('images/backbottom.gif') no-repeat;
}

a{text-decoration: underline;color: blue;}

Thanx

table = the table element <table> ... </table>

#contentBottom = the single element with this ID <div id="contentBottom"> ... </div>

.center = any and all elements with this class <div class="center"> ... </p>

HTH

Cordially, David

The id selector is used to specify a style for a single, unique element.

The id selector uses the id attribute of the HTML element, and is defined with a "#".
