Current methods for writing CSS require expert level ability just to get started.

Front-end engineering needs to accomodate entry level, mid level, and architect level developers, but our sites are too brittle. You may have a perfectly accessible or high performance website, and then the first newbie to touch it, ruins it. Our code should be robust enough that newbies can contribute while maintaining the standards weâ€™ve set.
