I would like the content of my website header to occupy 100% of the screen width on regular-sized desktops/laptops, but to be centered on larger displays. By \"larger displays\"
Try out setting media screen and limitation through min-width. http://www.w3schools.com/cssref/css3_pr_mediaquery.asp
@media screen and (min-width: 1200px) { .container { width: 100%; } } @media screen and (min-width: 1920px) { .container { width: 500px; } }
