HTML-CSS: Tips of the Day

What is the difference between id and class in CSS, and when should I use them?

Example:

<div id="header_id" class="header_class">
Text
</div>

#header_id {font-color:#fff}
.header_class {font-color:#000}

(Note that CSS uses the prefix # for IDs and . for Classes.)

However color was an HTML 4.01 <font> tag attribute deprecated in HTML 5. In CSS there is no "font-color", the style is color so the above should read:

Example:

<div id="header_id" class="header_class">
Text
</div>

#header_id {color:#fff}
.header_class {color:#000}

The text would be white.
