How do we Design a webpage using javascript and HTML to do change the background image on the click of a button?

put his in the style section:

.back {background-image: URL(background URL 1) ;}

.back1 {background-image: URL(background URL 2 ) ;}

.back2 {background-image: URL(backgroud URL 3) ;}

Put this code to where you want to put the buttons: (don't change anything except for the button name)
