Reading the blocks
Lessons use 20 kinds of block; tables sort and download, code and maths copy, and content from other sites asks first.
Lessons are built from 20 kinds of block. Most are there to read. These are the ones you can do something with.
| Block | What you can do |
|---|---|
| Checklist | Tick items off. The ticks are kept in this browser and do not count as progress. |
| Collapsible | Open and close it. |
| Table | Sort by a column when the table has a header row, and filter it in Filter rows… if the creator turned that on. Download CSV downloads every row. |
| Code | Copy it with one button. Lines the creator marked are highlighted, and long code expands. |
| Maths | Read the working line by line. If the creator set it, Next step shows one more line at a time. Each line's copy button copies its LaTeX. |
| Chart | Hover over a point to read its value. |
| Image | View full size. |
| Video | Play it in place. A YouTube video can start and stop where the creator set. |
| Audio | Play it in place, with Show transcript if there is one. |
| File | Download it. Every file in the course is also in the Resource Library. |
| Embed | A Figma board, a CodePen, a Google Doc or one of 16 services shown in place. Any other link opens in a new tab. |
The blocks you answer have articles of their own: Quizzes, Polls, Assignments, Discussions and Threads inside lessons.
