css - Do Modernizr tests include browser-prefixed functionality? -

when testing functionality using modernizr, this:

if (modernizr.csstransforms) {     $("#somediv").addclass('rotate'); } 

does modernizr test return true earlier browsers support prefixed applications of rule, e.g. -mz-transform, or test standard transform? read documentation can't find reference check.

the goal apply transforms if browser supports them. give example.

supposing .rotate class applies css 2d transform:

.rotate {transform:rotate(30deg)} 

would class need include prefixed transforms, or modernizr not account them? there's no point adding in prefixed versions if modernizr isn't looking them.

.rotate {-moz-transform:rotate(30deg);           -ms-transform:rotate(30deg);           -o-transform:rotate(30deg);           -webkit-transform:rotate(30deg);           transform:rotate(30deg)} 

modernizr tests against prefixed , prefixed versions. still need apply of css rules, however, since modernizr telling supports it, not specific rule works.

also, modernizr can add classes html element, don't need

if (modernizr.csstransforms) {     $("#somediv").addclass('rotate'); } 

because instead of

.rotate .foo {   transform:rotate(30deg) } 

you can do

. csstransforms .foo {   transform:rotate(30deg) }
