# - looks for a matching id


. - looks for a matching class

<p id="myID">....

<p class="myClass">....

@BrettNooyenAug 24.2006 — Standards wise you can use classes over and over, however ID is unique to only one item.

<div id="style5"></div>

<div id="style5"></div>

<div id="style5"></div>

That = bad.

<div class="style5"></div>

<div class="style5"></div>

<div class="style5"></div>

That = good.

Multiple elements my belong to the same class and an element may belong to multiple classes. The X/HTML class attribute's value may be a space separated list of classes.
