CSS3 fullscreen background image - contain and cover options


 / Published in: CSS
 

"Contain" maintains aspect ratio of the image while giving a full screen - will scale down but wont scale up beyond 100% of its own dimensions and doesn't repeat by default "Cover" will crop either crop or stretch the image to cover the full screen - seems to be setting image to 100% of screen size regardless of browser window size

  1. body{
  2. background-image: url(../images/bg.jpg);
  3. background-repeat: no-repeat;
  4. background-color: #000;
  5. background-size:contain;
  6. }
  7.  
  8. body{
  9. background-image: url(../images/bg.jpg);
  10. background-repeat: no-repeat;
  11. background-color: #000;
  12. background-size:cover;
  13. }
  14.  
  15. /* best choice below */
  16.  
  17. @media screen and (max-width: 1024px) { /* Specific to this particular image */
  18. img.bg {
  19. left: 50%;
  20. margin-left: -512px; /* 50% */
  21. }
  22. }
