    Just like pseudo-classes, pseudo-elements are added to selectors but instead of describing a special state, they allow you to style certain parts of a document. For example, the ::first-line pseudo-element targets only  the first line of an element specified by the selector.


    selector::pseudo-element {
      property: value;

    All pseudo-elements


    Sometimes you will see double colons (::) instead of just one (:). This is part of CSS3 and an attempt to distinguish between pseudo-classes and pseudo-elements. Most browsers support both values.

    Note: ::selection always starts with double colons (::).

    You can use only one pseudo-element in a selector. It must appear after the simple selectors in the statement.
