Advanced CSS Selectors: A Deep Dive

Explore advanced CSS selectors to gain surgical precision in your styling.

Beyond the Basics: Advanced CSS Selectors

You know the basics of CSS, but advanced selectors allow for surgical precision. Think of them as special tools to pick out exactly the elements you want to style, without needing extra classes or IDs.

The Attribute Selector

The [attribute] selector is used to style elements with a specific attribute. For example, input[type="submit"] targets only submit buttons. You can also match partial values using ~=, ^=, or *=.

Pseudo-classes & Pseudo-elements

Pseudo-classes select elements based on their state (e.g., :hover, :focus, :active). Pseudo-elements style parts of an element, like the first line (::first-line) or inserting content before or after (::before, ::after).
