In CSS, the `transform` property together with `scale` function and hover pseudo-class can be used to create a scaling effect. Here’s a simple example:
Consider an element with class “scale-on-hover”:
```
You can create a scaling effect that will be activated when hovered over with CSS like so:
```
.scale-on-hover {
/* Apply a transition to the transform property to animate the scaling */
transition: transform 0.5s;
.scale-on-hover:hover {
/* Scale the element to 150% its original size */
transform: scale(1.5);
}
```
Now when you hover over the element with the “scale-on-hover” class, it will scale up to 150% of its original size over the course of half a second. This can be a pleasant, eye-catching effect when used sparingly.
Note: Be aware that the scaling effect can make text unclear to read if it’s applied to an element containing text, particularly when scaling down.
