Background Images: background-repeat

You can re-size the dinosaur boxes using the grabber in the bottom right corner of each. CSS3 introduced space and round , and it has been supported in practically all browsers since 2010 . (Not supported in IE8 and earlier, or FF3 and earlier.)

This may be little more than a re-creation of https://codepen.io/chriscoyier/pen/vxgyRj + dinosaurs; but I learn well when I create my own demos. PS - holy Haleakalā! resize: both; overflow: hidden; is amazing!

background-repeat: repeat;

The default setting. The image is tiled throughout the element. Cut off the image at the edges.

background-repeat: space

Tile as with repeat , but don't crop the image (unless a single image won't fit). Add extra whitespace between images so that the element to its edges.

background-repeat: round

Tile as with repeat , but never crop the image. Change the size of images so that they fill the element to its edges.

background-size: cover;

Note that background-size: cover; properties override background-repeat .
