How to Combine :after and :hover Effectively
When utilizing CSS, it's possible to combine the :after and :hover pseudo-selectors to create dynamic effects. However, achieving this can be challenging.
Consider the provided code, where a list is enhanced with a selected class that adds an arrow shape using :after. The goal is to apply the same arrow shape to items that are being hovered over.
#alertlist {
list-style: none;
width: 250px;
}
#alertlist li {
padding: 5px 10px;
border-bottom: 1px solid #e9e9e9;
position: relative;
}
#alertlist li.selected,
#alertlist li:hover {
color: #f0f0f0;
background-color: #303030;
}
#alertlist li.selected:after {
position: absolute;
top: 0;
right: -10px;
bottom: 0;
border-top: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid #303030;
content: "";
}
To combine the :after effect with :hover, simply append :after to the #alertlist li:hover selector in the same way it's done for #alertlist li.selected:
#alertlist li.selected:after, #alertlist li:hover:after
{
position:absolute;
top: 0;
right:-10px;
bottom:0;
border-top: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid #303030;
content: "";
}
By doing this, the arrow shape will now appear on both list items with the selected class and items that are being hovered over.

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.
