CSS Nesting: More Complex Style Management
CSS nesting is a relatively new feature of CSS that allows you to directly nest classes within each other without resorting to complex selectors. This can greatly simplify your stylesheets and make them easier to understand.
Can CSS Classes Be Nested?
Traditionally, CSS classes could not be nested directly within each other. However, with the introduction of the CSS Nesting Module, this is now possible.
How to Nest CSS Classes
CSS nesting follows a simple syntax:
.parent-class { & child-class1 { // Child class properties } & child-class2 { // Child class properties } }
The & symbol within the child class rules refers to the parent class. This allows you to easily apply styles to nested elements without repeating the parent class name.
Browser Support
CSS nesting is currently supported in all major browsers. However, it is important to note that it is still a relatively new feature and may not be supported in older browsers.
Examples:
Here are a few examples of how CSS nesting can be used to create more complex and specific styles:
- Table styling:
table.colortable { & td { text-align: center; & .c { text-transform: uppercase } & :first-child, & :first-child + td { border: 1px solid black } } & th { text-align: center; background: black; color: white; } }
- Component class inheritance:
.container { color: red; & .child { color: blue; } }
- Parent and child class inheritance:
body { color: black; & #content { & .header { font-weight: bold; & h1 { color: red; } } } }
By utilizing CSS nesting, you can organize your stylesheets more efficiently, reduce code repetition, and create more maintainable and scalable styles.

Choosing Flexbox or Grid depends on the layout requirements: 1) Flexbox is suitable for one-dimensional layouts, such as navigation bar; 2) Grid is suitable for two-dimensional layouts, such as magazine layouts. The two can be used in the project to improve the layout effect.

For small adjustments, inline CSS can be used, but should be used with caution. 3. Large projects can use CSS preprocessors such as Sass or Less to import other CSS files through @import. 4. For performance, CSS files should be merged and CDN should be used, and compressed using tools such as CSSNano.
