Targets a single element with a specific ID attribute.

#my-id {
  background-color: yellow;
}

Attribute Selector

Targets elements based on their attribute values.

input[type="text"] {

}

Combining Selectors

Selectors can be combined to create more specific targeting.

}

Pseudo-classes and Pseudo-elements

Pseudo-classes and pseudo-elements target elements based on their state or position in the document.

a:hover {
  color: red;
