## Description
<section id='description'>
To change the scale of an element, CSS has the <code>transform</code> property, along with its <code>scale()</code> function. The following code example doubles the size of all the paragraph elements on the page:
<blockquote>p {<br>&nbsp;&nbsp;transform: scale(2);<br>}</blockquote>
</section>

## Instructions
<section id='instructions'>
Increase the size of the element with the id of <code>ball2</code> to 1.5 times its original size.
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: Set the <code>transform</code> property for <code>#ball2</code> to scale it 1.5 times its size.
    testString: assert(code.match(/#ball2\s*?{\s*?left:\s*?65%;\s*?transform:\s*?scale\(1\.5\);\s*?}|#ball2\s*?{\s*?transform:\s*?scale\(1\.5\);\s*?left:\s*?65%;\s*?}/gi), 'Set the <code>transform</code> property for <code>#ball2</code> to scale it 1.5 times its size.');
