-### Basic example
+### Comparing :focus and :focus-visible
 
-In this example, the `:focus-visible` selector uses the UA's behavior to determine when to match. Compare what happens when you click on the different controls with a mouse, versus when you tab through them using a keyboard. Note the difference in behavior from elements styled with `:focus`.
+This example presents three pairs of controls. Each pair consists of a [`text`](/en-US/docs/Web/HTML/Element/input/text) input and a button.
+
+- The first pair does not add any custom styles for focus states, and shows the default case.
+- The second pair adds styles using the `:focus` pseudo-class.
+- The third pair add styles using the `:focus-visible` pseudo-class.

+If you click each element in turn, you will see that when `:focus` is used to style the focus ring, the UA draws the focus ring when the user clicks the button. However, when `:focus-visible` is used to style the focus ring, the UA does not draw the focus ring when the user clicks the button, just like in the default case.
+
+If you then tab through each element, you will see that in all three cases — default, `:focus`, `:focus-visible` — the UA draws the focus ring around the button when the user navigates to it with the keyboard.
+
+This shows how `:focus-visible` enables a designer to follow the browser's logic in determining when a focus ring should be shown.
