<style type="text/css">
p { background: yellow; }
</style>
...
<p>Element Selector Example</p>

A class selector begins with a period. A style can be applied to multiple elements using a class selector. The following 'testClass' class selector creates a background of orange. It is applied to two <p> elements that have their class attribute set to 'testClass'.

<style type="text/css">
.testClass { background: orange; }
</style>
...
<p class="testClass">Class Selector Example</p>
<p class="testClass">Class Selector Example 2</p>

<style type="text/css">
#testId { background: aqua; }
</style>
...
<p id="testId">ID Selector Example</p>

This generates the following output:
