## Description
<section id='description'>
You can set a checkbox or radio button to be checked by default using the <code>checked</code> attribute.
To do this, just add the word "checked" to the inside of an input element. For example:
<code>&#60;input type="radio" name="test-name" checked&#62;</code>

## Instructions
