How can i change the color of the mapping selection (area)?
This css: "area { background-color: red; }" does not work.

```
<img id="map1" src="images/bg.png" usemap="#map1" />
    <map name="map1">
        <area shape="poly" onclick="openNav()" shape="poly" coords="902,516,936,496,940,535"/>
    </map>

```

A hover would be nice, but just to reach it and change the background is a good start.
