Styling an element on hover in CSS is fairly straightforward. You use the `:hover` pseudo-class to add styles that will be applied when user hover over that specific element.
```
.exampleClass:hover {
color: blue;
background-color: yellow;
}
```
This example will change the text color to blue and background color to yellow when the mouse is hovered over any element with the `.exampleClass` class.
Note that hover styles will only be applied if the user’s device has a mouse. On touch screens (like smartphones and tablets), there is typically no concept of “hovering”, so you may need to design your styles accordingly.
