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.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
