Coding exercise

I’d like to introduce my students to coding–not because I’ll expect them to build something from scratch (unless they want to) but basically to demystify how pages are constructed and structured. I could imagine an activity in which they go through the CSS and HTML lesson on Codeacademy as a weekend assignment. During the next class period we would then discuss their experience; perhaps we could also have a web services staff member on hand and then, using Firebug, look at the coding of digital history sites (again to explain and demystify).
