How to Highlight Active Menu Items and Dim Non-Active Ones
In this code snippet, we encounter a scenario where we want to dim the opacity of all menu items (
- ) is hovered. However, the hovered menu item itself should remain at full opacity.
CSS Solution
To achieve this effect, we utilize CSS to dynamically adjust the opacity of the menu items:
ul:hover li {
opacity: 0.5;
}
ul li:hover {
opacity: 1;
}
Explanation:
- The first rule (ul:hover li) applies an opacity of 0.5 to all
- elements when their parent
- is hovered. This dims the menu items that are not currently being hovered over.
- The second rule (ul li:hover) resets the opacity to 1 for the
- element that is actually being hovered over. This ensures that the current menu item remains at full visibility.
Example
Consider the following HTML and CSS code:
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
<style>
li {
float: left;
width: 33.33%;
line-height: 50px;
background: gray;
list-style-type: none;
}
ul:hover li {
opacity: 0.5;
}
ul li:hover {
opacity: 1;
}
</style>
When you hover over the
- element, all
- elements except the one you're hovering over will become 50% transparent, while the hovered
- element will remain at full opacity. This creates a subtle highlight effect, guiding users to the active menu item.

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.
