Fullscreen responsive background image in CSS

jsBin demo

background: url(image.jpg) fixed 50%;
background-size: cover;                 /* PS: Use separately here cause of Safari bug */

The fixed (background-attachment) is optional.


The above is just a shorthand for:

background-image      : url(image.jpg);
background-attachment : fixed;
background-position   : 50% 50%;     /* or: center center */
background-size       : cover;       /* CSS3 */

You’ve could in all modern browsers but Safari use:

background: url(image.jpg) fixed 50% / cover;

where the / is used in background shorthand to separate and distinguish position from size (cause position accepts both single and multiple (X,Y) values), but Safari has a bug with this / shorthand so use as described above.
