❓ FAQ

QWhat are common use cases for h5?

AFifth-level headings in deep documents, such as clause subdivisions in technical specifications or numbered levels in legal texts. It is rare in practice — most pages need four levels or fewer. If h5 comes up often, the structure is probably too deep; consider splitting the page.

QIs the only difference between h5 and h4 the font size?

ASemantically it is one level down; visually the browser default shrinks slightly. The real difference is position in the document outline: h5 belongs to the nearest h4. Styles can change anytime — the hierarchy is the substance.

QCan I use h5 for sidebar widget titles?

ANot recommended. Sidebar widget titles are usually not part of the content heading hierarchy; h2-h6 would pollute the document outline. Better options: a <p> with a class, or an <nav> with an aria-label describing the region.
