##There are three basic parts to this.

###There is a mixin for every property that uses rems

Feel free to add to my list I currently support the following: *height *min-height *max-height *width *min-width *max-width *font *font-size *line-height *border *border-width *outline *outline-width *padding *padding-top *padding-bottom *padding-left *padding-right *margin *margin-top *margin-bottom *margin-left *margin-right *background *background-position

###rem-to-px(prop, args)

Each mixin calls the rem-to-px function This prints out a pixel version, followed by a rem version of the property prop: the property name args: the set of arguments being passed to the property

###get-px(args)

This function is called by the rem-to-px function and returns a pixel version of the property if needed, otherwise it returns false. args: property arguments
