Use the CSS Transform scale Property to Scale an Element on Hover

The transform property has a variety of functions that let you scale, move, rotate, skew, etc., your elements.

When used with pseudo-classes such as :hover that specify a certain state of an element, the transform property can easily add interactivity to your elements.

Here's an example to scale the paragraph elements to 2.1 times their original size when a user hovers over them:

p:hover {
  transform: scale(2.1);
}

Note: Applying a transform to a div element will also affect any child elements contained in the div.
