Web Design Training

[Zholl]

Alright, so this year I'm in charge of my team's website. This means that I'll be helping with the newbies who decide to join the web design group this year. At this point, I pretty much get what I'm doing, but I'm not sure of the best way of teaching it to these underclassmen. I'm thinking of a sort of sandbox approach, where maybe I can have them play with existing pages, and take care of updates to get used to the code, but without actually changing the page itself unless I approve what they've done. I figure before that I can teach them basic HTML tags and CSS, and that should teach them enough to handle general updating. I figure if I let them sandbox everything else, by the time I graduate at least one of them should have enough of an understanding of the site to handle it after I leave.
So should I change up my current method? This is my first year in leadership, and only the second year of the site's existence, so I'm not really sure what I'm doing here. Also, is there anything else I'm forgetting to teach?
