CSS selectors allow you to target and style a specific state (pseudo-class), part (pseudo-element) or child of an element. You can also use them to target specific browsers using a prefix.

For example:

• Use the :hover (pseudo-class) selector to change the style of an element when the mouse hovers over it 
• Use the :before (pseudo-element) selector to add content before an element
• Use the :first-child (pseudo-element) selector to style the first child of an element

• Within the Style editor, click on the Style tree button. This will say Default on it
• The menu that opens is called the Style tree
• Click on the blue + Icon and then click on :hover in the next menu
• The menu will close and :hover will now be in the Style tree
• Click on :hover
