What are the best practices for CSS nesting?

CSS nesting allows you to write cleaner and more maintainable styles. Best practices include keeping nesting levels shallow, using meaningful class names, and avoiding deep nesting to prevent specificity issues.

Can you give an example of shallow nesting?

Sure! Instead of nesting too deeply like this:

.header {
  .nav {
    .item {
      color: blue;
    }
  }
}

You can keep it shallow:

.header {
  color: red;
}
.nav {
  color: blue;
}

What tools can help with CSS nesting?

Tools like Sass and Less are great for CSS nesting. They allow you to write nested styles while compiling them into standard CSS.

Are there any performance concerns with CSS nesting?

Yes, excessive nesting can lead to larger CSS files and slower rendering times. It's best to balance readability with performance.
