Compass vendor prefixes does not include Opera prefix

I've installed compass recently to get benefit from its features, especially the vendor prefixes.

When I do something like this :

@include box-sizing(border-box);

I get :

-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;

But what about other prefixes like Opera prefix -o-box-sizing ?

Solution

  • Compass does not blindly add vendor prefixes to every property, it only adds the ones that browsers actually use by checking with caniuse.com. Opera has never required prefixes for the box-sizing property, so Compass does not add it.
