## Description
<section id='description'>
CSS has a property called <code>width</code> that controls an element's width. Just like with fonts, we'll use <code>px</code> (pixels) to specify the image's width.
For example, if we wanted to create a CSS class called <code>larger-image</code> that gave HTML elements a width of 500 pixels, we'd use:
<blockquote>&#60;style&#62;<br>&nbsp;&nbsp;.larger-image {<br>&nbsp;&nbsp;&nbsp;&nbsp;width: 500px;<br>&nbsp;&nbsp;}<br>&#60;/style&#62;</blockquote>
</section>

## Instructions
<section id='instructions'>
Create a class called <code>smaller-image</code> and use it to resize the image so that it's only 100 pixels wide.
<strong>Note</strong><br>Due to browser implementation differences, you may need to be at 100% zoom to pass the tests on this challenge.

## Tests
<section id='tests'>

```yml
tests:
  - text: Your <code>img</code> element should have the class <code>smaller-image</code>.
    testString: assert($("img[src='https://bit.ly/fcc-relaxing-cat']").attr('class') === "smaller-image", 'Your <code>img</code> element should have the class <code>smaller-image</code>.');
  - text: Your image should be 100 pixels wide. Browser zoom should be at 100%.
    testString: assert($("img").width() === 100, 'Your image should be 100 pixels wide. Browser zoom should be at 100%.');
