Labels
Write short, clear labels, one or two words max in most cases. Use parallel construction--every item should be a noun or a verb. Avoid repeating words if possible.
Title case
Use title case--capitalize the first letter of every word. Never use ALL CAPS in tab labels because it’s harder for the user to read.²
Stacked tabs group heading
The tab heading should clearly describe how the group of tabs are related.
