Why does it add `*zoom: 1`?

Very interesting project.

My question is why is the output of, say, lost-utility: clearfix adding a *zoom: 1 declaration in there? there are other places where it does that too.

calc() can only be used by IE9+ so it doesn't make sense to me that lost is outputting *zoom rules which are meant to address issues for < IE7.

Thanks!

With the calc polyfill I believe calc works in IE7. Regardless it's good practice to support older browsers if it doesn't hurt anything.
