Semantics vs. styles

The definitions covered here refer to typographic styles. It’s important to understand the separation of styles and semantics:

  • The semantics of a page inform the hierarchy and relationships, making text logically structured for screen readers and other assistive technologies.
  • Styles are used to ensure optimal readability and legibility, as well as convey brand.

Without semantically correct HTML, content won’t be accessible. Consider, for example, the following guidance on headings:

  • The page headings must follow an order, starting from H1 to H6.
  • A page must only have one H1 element.
  • Ensure heading levels are sequential: H1, H2 then H3. Not H1, H3 then H2.

It is possible to style each heading. A suitable style may be applied on each of these headings. To avoid confusion, the following should be remembered:

  • Refer to H1, H2, etc. only when it comes to semantic choices and accessibility.
  • Use Nucleus naming conventions to discuss typographic style choices.
