Formatting Tabbed Blocks
Use tabbed blocks to present information to your users in a concise page.
There are two styles of tabbed blocks which can be used to consolidate information on your page, regular tabs and expander tabs. Converting regular blocks into tabbed blocks happens at the column level.
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.
