title: Change the Position of Overlapping Elements with the z-index Property

## Description
When elements are positioned to overlap (i.e. using position: absolute | relative | fixed | sticky
), the element coming later in the HTML markup will, by default, appear on the top of the other elements. However, the z-index
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 z-index
property of an element move it higher in the stack than those with lower values.
## Instructions
Add a z-index
property to the element with the class name of first
(the red rectangle) and set it to a value of 2 so it covers the other element (blue rectangle).
## Tests
```yml
tests:
- text: The element with class first
should have a z-index
value of 2.
testString: assert($('.first').css('z-index') == '2', 'The element with class first
should have a z-index
value of 2.');
```
