In CSS, a class selector (or class style rule, or class style, etc.) is a selector which selects zero or more HTML elements based on the elements' class attribute.

Example

Class selector:

.example { color: red; }

Note the period (.) which indicates that this is a class style rule.

Element affected by rule:

<div class="example">...</div>
<p class="example">...</p>

The above example demonstrates that a class rule can affect two or more HTML elements, and that the elements can be different types.

• This is somewhat artificial, as a classroom example
• More commonly, a class rule affects HTML elements of the same type
