Now suppose we wanted to change the hover from dark blue text on light gray background with no underline to green text on yellow background with underline. Simply open the stylesheet, go to the a:hover selector, and change it to read:

a:hover { /* Green text on yellow background */
color : #008000;
background-color : #FFFF00;
}
