It works ?

Question

*{
background:red;
}
and
*{
background-color:red;
}
are the same command ? Both work to me. Is it a problem ?

Answer 1

This is intended. The background property is a shortcut for background-color and several others.

Answer 2

thanks :)

Answer 3

background: red is for html used in pass
Backgroud-color:red; is new
both will work but need to use the last one.
