title: Add id Attributes to Bootstrap Elements
challengeType: 0
---

## Description
<section id='description'>
Recall that in addition to class attributes, you can give each of your elements an <code>id</code> attribute.
Each id must be unique to a specific element and used only once per page.
Let's give a unique id to each of our <code>div</code> elements of class <code>well</code>.
Remember that you can give an element an id like this:
<code>&#60;div class="well" id="center-well"&#62;</code>
Give the well on the left the id of <code>left-well</code>. Give the well on the right the id of <code>right-well</code>.
