## Description
|
|
<section id='description'>
|
|
In addition to classes, each HTML element can also have an <code>id</code> attribute.
|
|
There are several benefits to using <code>id</code> attributes: You can use an <code>id</code> to style a single element and later you'll learn that you can use them to select and modify specific elements with JavaScript.
|
|
<code>id</code> attributes should be unique. Browsers won't enforce this, but it is a widely agreed upon best practice. So please don't give more than one element the same <code>id</code> attribute.
|
|
Here's an example of how you give your <code>h2</code> element the id of <code>cat-photo-app</code>:
|
|
<code><h2 id="cat-photo-app"></code>
|
|
</section>
|
|
|
|
## Instructions

|
