Select the first <p> element:
The :first selector selects the first element.
Note: This selector can only select one single element. Use the :first-child selector to select more than one element (one for each parent).
This is mostly used together with another selector to select the first element in a group (like in the example above).
Tip: To select the last element in a group, use the :last selector.
