## Description
<section id='description'>
When elements are positioned to overlap, the element coming later in the HTML markup will, by default, appear on the top of the other elements. However, the <code>z-index</code> property can specify the order of how elements are stacked on top of one another. It must be an integer (i.e. a whole number and not a decimal), and higher values for the <code>z-index</code> property of an element move it higher in the stack than those with lower values.
</section>

## Instructions
<section id='instructions'>
Add a <code>z-index</code> property to the element with the class name of <code>first</code> (the red rectangle) and set it to a value of 2 so it covers the other element (blue rectangle).
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: The element with class <code>first</code> should have a <code>z-index</code> value of 2.
    testString: assert($('.first').css('z-index') == '2', 'The element with class <code>first</code> should have a <code>z-index</code> value of 2.');

```
