Superscripts and trademarks are characters that are set slightly above normal lines of texts.
Used to indicate there are related disclaimers or footnotes.
Where possible, avoid using superscripts as they are not accessible. When superscripts are used, the customer needs to switch between reading the body copy and where the detail is located, which is usually at the bottom of a page.
Instead, include the detail in the body copy.
Trademarks and registered business names must appear as per their respective guidelines, including the use of symbols – see the Marketing Checklists of products and categories.
