| 587d78a3367417b2b2512acf | Change the Position of Overlapping Elements with the z-index Property | 0 | https://scrimba.com/c/cM94aHk | 301046 | 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).
--hints--
The element with class first should have a z-index value of 2.
assert($('.first').css('z-index') == '2');
