CSS selectors are used to "find" (or select) the HTML elements you want to style.

We can divide CSS selectors into five categories:

• Simple selectors (select elements based on name, id & class)

• Combinator selectors (select elements based on a specific relationship between them)

• Pseudo-class selectors (select elements based on a certain state)

• Pseudo-elements selectors (select and style a part of an element)

• Attribute selectors (select elements based on an attribute or attribute value)
