When should I use CSS nesting?

What is CSS nesting and when should I use it?

CSS nesting allows you to write CSS rules inside other rules, making your stylesheets more organized and easier to read. You should use it when you have a clear hierarchy in your HTML structure.

Are there any performance concerns with using CSS nesting?

Yes, excessive nesting can lead to more complex selectors, which may impact performance. It's best to keep nesting to a reasonable level.

Can you give me an example of CSS nesting?

Sure! Here's a simple example:

nav {
  background: #333;
  ul {
    list-style: none;
    li {
      display: inline;
      a {
        color: white;
      }
    }
  }
}

When is it better to avoid CSS nesting?

Avoid CSS nesting when it complicates your styles or when you're working on a large project where maintainability is key. Stick to simpler selectors for better performance.
