Can CSS Be Used to Style Mouseover Effects on Image Maps?

Creating a webpage with an image that includes links can be achieved using an image map. However, adding a touch of interactivity by styling the area shapes on mouseover can enhance the user experience. Is this possible using CSS?

Let's consider the following code:

<img src="{main_photo}" alt="locations map" usemap="#location-map" />
<map name="location-map">
    <area shape="rect" coords="208,230,290,245" href="{site_url}locations/grand_bay_al" />
    <area shape="rect" coords="307,214,364,226" href="{site_url}locations/mobile_al" />
    <area shape="rect" coords="317,276,375,290" href="{site_url}locations/loxley_al" />
</map>

area { border: 1px solid #d5d5d5; }

Despite attempts, this code fails to style the area shapes on mouseover.

CSS-Only Solution:

Instead of using the image map approach, an alternative method using CSS's :hover pseudo-class is available. Here's an example:

<div class="area"></div>
<div class="area"></div>
<img src="image.jpg" />

.area {
    background: #fff;
    display: block;
    height: [desired height];
    opacity: 0;
    position: absolute;
    width: [desired width];
}
.area:hover {
    opacity: 0.2;
}

Explanation:

• The image is placed at the bottom layer.
• Two div elements are positioned absolutely on top of the image with an opacity of 0.
• When the mouse hovers over these div elements, the opacity increases to 0.2, revealing the content behind them.

This method provides a simple and elegant way to add mouseover effects to specific areas of an image using CSS.
