h1 {

  font-family: 'Arial', sans-serif;

  font-size: 24px;

}

3. Class Selector - Style Elements with Specific Classes:

Class selectors are preceded by a dot (.) and are used to style elements with specific class attributes.

}

Child selectors target elements that are direct children of a parent element.


ul > li {

  list-style-type: square;

}

7. Adjacent Sibling Selector - Style Immediately Following Elements:

This selector targets an element that directly follows another element.


h2 + p {

  font-style: italic;

}

Enter fullscreen mode Exit fullscreen mode

8. General Sibling Selector - Target Sibling Elements:

The general sibling selector selects elements that share the same parent and are at the same level in the hierarchy.

  color: #888;

}

9. Attribute Selector - Style Elements with Specific Attributes:

Attribute selectors allow you to target elements based on specific attribute values.


input[type="text"] {

Pseudo-classes target elements based on their states or interactions.

  content: ">>";

}

12. Grouping Selector - Apply Styles to Multiple Elements:

Grouping selectors allow you to apply the same styles to multiple selectors.

}

13. Not Selector (:not(selector)) - Exclude Specific Elements:

The :not() pseudo-class excludes elements that match a certain selector.
