Tabs make it easy to view and navigate stacked panels of related content.
Tabbed interfaces, like accordions, allow users to view long-form content one section at a time. Clearly labelled tabs representing the individual sections make it easy for users to identify and reveal the content pertinent to them.
Use tabs where the subject sections are not too numerous (more than four or five tabs in total) and the tab labels are not lengthy. Tab content should be self-sufficient: do not force users to switch back and forth between tabs to complete tasks. Where more than five sections/labels are present, or the tab labels are lengthy, an Accordion pattern is preferred.
