<p>Since many years a GUI-standard are the menu-bars of applications with menus popping up, if you click or hover an entry in the menu-bar. Some websites implement this feature too, but they are using Javascript, as far as  I can see. For different reasons Javascript can be a problem, so the question: Is this possible to implement without Javascript, only using HTML and CSS?</p>

You can use the pseudoclass :hover to get an hover effect.
```
```
a:link {
 color: blue;
}

a:hover {
  color: red;
}
```
```
I can give a more extensive example but not right now (need to get the kids to the dentist).
