Two changes to "center()", to make it work more like Jeet's center() function: 1. Add check for % as value, eg. "center(75%)" for responsive container width. 2. Add 2nd optional variable, "pad", to specify left and right padding. eg. "center(100%, 5%)" for reponsive container padding. Not completely sure I'm using the unit() function correctly, but it works in my build environment.
