Write a CSS code to provide an animation on hover.
Here is one example of CSS code that provides an animation on hover:

```css
.my-hover-element {
  width: 100px;
  height: 100px;
  background: #3498db;
  transition: all 0.5s;
}

.my-hover-element:hover {
  background: #9b59b6;
  transform: scale(1.5);
}
```

This code creates an element with a class `my-hover-element` and sets its width, height, and background color. It also sets a `transition` property, which specifies how long the animations should take when triggered. In this case, the animations will take 0.5 seconds to complete.

The second set of CSS rules target the `:hover` state of the `.my-hover-element` class. When a user hovers their mouse over an element with this class, its background color will change, and it will be scaled up to 150% of its original size. This creates an attention-grabbing animation that could be used, for example, to make buttons more interesting or to draw attention to important elements on a webpage.

Of course, this is just one example of an animation that you could create on hover - there are countless possibilities! You could experiment with other animations, such as rotating or skewing the element, changing its opacity, or animating its position on the page.
