Courses Plus Student 8,447 PointsWhat is the **contain** value useful for when using the background-size property?
Hi I'm unable to figure out when the contain value for the background-size property might be useful. It seems to clip the image allowing for white spaces. In today's modern browsers that resize it seems to be an outdated rule. Can someone help me understand? thanks.

This is in contrast to the cover value:
"The cover value specifies that the background image should be sized so that it is as small as possible while ensuring that both dimensions are greater than or equal to the corresponding size of the container."

These can always be used in web apps, but many of the needs around this come from the new demands of mobile sizing.

Here's a good site with some good examples. Scroll down the page and read the cover and contain section. I'm horrible at explain things in my own words but I know how to use the declaration contain. I hope this helps out.
