Commencing in early 2016, the Chem1 lesson sets are gradually being updated to current standards, including HTML-5, CSS3, addition of microdata, and "responsiveness" — i.e., ability to adapt to tablets and hand-held devices. The latter is a rather labor-intensive task, and will begin with the more elementary sections.
