--- id: 587d78a3367417b2b2512acf title: Change the Position of Overlapping Elements with the z-index Property challengeType: 0 videoUrl: 'https://scrimba.com/c/cM94aHk' --- ## 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 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.'); ```
