The Chem1 lesson sets are gradually being updated to current standards, including HTML-5, CSS3, addition of microdata. This process commenced in 2016, and is still underway. Beginning in 2019, it is anticipated that some of the more popular units made "responsive" — i.e.,able to adapt to tablets and hand-held devices.
