Nesting CSS Classes: A Revolution in CSS Design
In the past, CSS nesting was not possible, but with the introduction of the CSS Nesting Module, it's now a reality. This allows you to nest rules within other rules, creating a more maintainable and manageable CSS codebase.
Syntax of CSS Nesting
The syntax of CSS nesting is straightforward:
parent-class {
& selector {
declarations;
}
}
In this syntax, the & symbol represents the parent selector. It allows you to target child selectors within the parent class.
Examples of CSS Nesting
Here are a few examples of how you can use CSS nesting:
/* Apply styles to all `<td>` elements within `.colortable` */
table.colortable {
& td {
text-align:center;
}
}
/* Apply styles to the first `<td>` element and its adjacent sibling within `.colortable` */
table.colortable {
& td:first-child, & td:first-child + td {
border:1px solid black;
}
}
/* Apply styles to all `<th>` elements within `.colortable` */
table.colortable {
& th {
text-align:center;
background:black;
color:white;
}
}
/* Apply styles to `.bar` elements that are children of `.foo` */
.foo {
color: red;
& > .bar {
color: blue;
}
}
/* Apply styles to `.parent` elements that contain `.foo` elements */
.foo {
color: red;
& .parent & {
color: blue;
}
}
Browser Support for CSS Nesting
CSS nesting is supported in all major browsers, including:
- Chrome
- Firefox
- Safari
- Edge

With CSS nesting, you can create more organized and maintainable CSS code that is easier to read and understand.

How can I include CSS only on some pages?
Jun 11, 2025 am 12:01 AM
There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

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.
