We'll then add a colon (:) followed by how we want to change the property. In this case, we'll change the color to gray.

<html>
 <body style="background-color:gray;">
  I come in many shades of gray.
 </body>
</html>
]]>

Obviously, we can change it to any other color we want.

We'll first add the colon,(:) and then the word gray.
