Page Title (H1)
Use underlines for links in body copy with no underline on hover/focus. For standalone links, such as a privacy link at the bottom of a page, use no underline and show underline on hover/focus.
For abbreviations, such as HRIS, show the expanded text after the first use, such as "HRIS (human resource information system)" and abbreviations thereafter. If there's not enough space or only one use, you might instead show an abbreviation using a dotted underline and use a tooltip to expand the abbreviation on hover/focus.
Here are some examples of typography in existing design systems and typography references:
