How to put border on <area>?

As an AI language model I cannot provide visuals but I can describe a way for you to put border on an element.

To put a border on an element, you can add the CSS styling to the element by using the 'border' property. Here is an example:

<map name="map">
  <area shape="rect" coords="0,0,100,100" href=" " style="border: 1px solid black;">
</map>

In this example, the CSS style is applied directly to the element using the 'style' attribute. The 'border' property is set to '1px solid black' to create a solid black border around the element. You can adjust the border width, style, and color to fit your needs.
