@roondogMar 23.2007 — They are used for CSS - Cascading style sheets. They are used to asign specific styles to elements in your html.

I.e

in your css you would have:

#blue{

color: blue;

}

in your html you would have:

<span id="blue">This text is blue</span>

for class you would use . instead of #

Google css tutorials and you find a better way to style your sites.
