								The CSS “class” selector is used to apply the same styling to multiple elements on the page. A great way to think of this would be like the blueprint of a car or building. The blueprint will allow you to build several cars or several buildings in the same manner after designing the actual layout once.

								### Use Cases
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								Unlike the CSS “ID” class names are not unique. Therefore, it is fine for you to use a “class” several times if you would like for these elements to have the same styling applied. In fact, this would be a great time for you to use a “class.” If you would like for three “div” elements in your HTML to have a blue background you could use a class once in your CSS as seen in the example below.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								```
							 | 
						||
| 
								 | 
							
								<html>
							 | 
						||
| 
								 | 
							
								<style>
							 | 
						||
| 
								 | 
							
								  .blueBg {
							 | 
						||
| 
								 | 
							
								    background-color: blue;
							 | 
						||
| 
								 | 
							
								  }
							 | 
						||
| 
								 | 
							
								</style>
							 | 
						||
| 
								 | 
							
								  <body>
							 | 
						||
| 
								 | 
							
								    <div class="blueBg"></div>
							 | 
						||
| 
								 | 
							
								    <div class="blueBg"></div>
							 | 
						||
| 
								 | 
							
								    <div class="blueBg"></div>
							 | 
						||
| 
								 | 
							
								  </body>
							 | 
						||
| 
								 | 
							
								</html>
							 | 
						||
| 
								 | 
							
								```
