What is the method for reversing the colors on a specific portion of an element?

Picture this scenario: you have a square shaped div with the following styling:

div {
  background: red;
  height: 5rem;
  width: 5rem;
}

How would you modify its styling so that the color of the bottom half of the red square is inverted?

Answer №1

One option is to utilize the CSS filter function invert

div {
	  background: red;
	  height: 5rem;
	  width: 5rem;
	  position: relative;
	}

	div > div {
	  background: red;
	  height: 2.5rem;
	  width: 100%;
	  filter: invert(1);
	  position: absolute;
	  bottom: 0;
	}
<div>
	  <div>
	  </div>
	</div>
