All the blue boxes are actually interactive code editors. You can run arbitrary queries against the dataset in them. I changed some of the wording to make it clearer. Hopefully that helps!



I was wondering what you were talking about. What blue boxes? Then I saw the problem. The boxes showed up in Chromium but not Firefox.


Same here - the front matter page mentions web components - perhaps the support is different /disabled in Firefox?

The <sql-exercise data-question...> elements aren't visible in Firefox at all.
