How do you place a background image for your profile

body{

background-image: url(https://i.pinimg.com/736x/72/40/83/724083bb2f1f66098dd28e7ad0b8098f.jpg);

background-size: cover}

to use an image you need to copy the image address where the link goes, alternatively you can use an image hosting site (i use imgbb) to make sure the image isnt deleted 

thanks so much
