Use a CSS Class to Style an Element

Classes are reusable styles that can be added to HTML elements.

Here's an example CSS class declaration:

<style> .blue-text { color: blue; } </style>

You can see that we've created a CSS class called blue-text within the <style> tag. You can apply a class to an HTML element like this: <h2 class="blue-text">CatPhotoApp</h2>. Note that in your CSS style element, class names start with a period. In your HTML elements' class attribute, the class name does not include the period.

 

TEST

Inside your style element, change the h2 selector to .red-text and update the color's value from blue to red.

Give your h2 element the class attribute with a value of red-text.

 

<style>
  .red-text {
    color: red;
  }
</style>

<h2 class="red-text">CatPhotoApp</h2>
