Transitions bug

[SerafimArts]

@include transition(background .3s ease);

Should be:

-webkit-transition: background 0.3s ease;
-moz-transition: background 0.3s ease;
-o-transition: background 0.3s ease;
transition: background 0.3s ease;

Instead:

-webkit-transition: background, 0.3s, ease;
-moz-transition: background, 0.3s, ease;
-o-transition: background, 0.3s, ease;
transition: background 0.3s ease;

Commas appear in expressions with prefixes
