In CSS, a class rule (or class style rule, or class style) is a style rule which selects zero or more HTML elements based on the elements' class attribute.
Example
Class style rule:
.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
Example: multiple class rules
