Need to stylize area tag inside map

Question

I have image and areas located inside

Answer 1

Isn't possible with css to change assign style to area directly.
Another way is to use SVG file

Here's an example I whipped up: JSFIDDLE.

in the example you have this css that can make a style to your svg:

polygon.hoverable
{
    fill: transparent;
    stroke:gray; /* Replace with none if you like */
    stroke-width: 4;
    cursor: pointer;
}

polygon.hoverable:hover
{
 stroke:black;   
}

Other way is to use some plugin in javascript/jQuery like this:
