Create a spinning block
Designing a content block with two sides of information.
An interactive, dual-sided block can be useful to help defer complexity for users, allowing access to deeper information only when needed.
Use h4 for section headings
If you don't want numbers in the section headings, simply remove the "numbered" class from this block.
Note/Tip/Warning/Info blocks below are collapsed by default. If you want to use any of these, try to keep to just one per page. You may use two if necessary, but in general, try to limit these.
