We started with a short recap of homework, then spent the rest of the day with basic HTML and CSS.

We followed this presentation on HTML and CSS. (On GitHub: presentation source code).

To practice, everyone checked out this repository, which contained empty pages and empty css files: hello-html-and-css-world. Some pushed their changes at the end, but that was not the main focus of the session.

Key concepts covered (see presentation for all)

basic html structure
basic html tags
static pages
relative links and image references
css selectors

Homework: further experiment with the hello-html-and-css-world files locally, possibly add content that could be part of their projects.
