Choosing the Correct HTML Tag for Bold Text

Choosing the Correct HTML Tag for Bold Text

Verified Sources
Sep 12, 2026

To make text bold in HTML, you must use the correct, standardized element names—HTML does not recognize invented tags like <bold>, <bb>, or <bld>.

A key distinction is:

For your multiple-choice options, the correct bold tag among them is (i) <b>. The other options are not valid HTML elements and will not produce the intended bold formatting in standards-compliant rendering.

In HTML, <b> is the element for “stylistically offset text” (typically rendered bold) without indicating semantic importance.
If you want semantic importance (not just visual boldness), use <strong> instead.

Key terms: [HTML element]{def="A named tag with semantics, e.g., or , defined by the HTML specification"} Void/valid element Semantics Visual styling.

HTML <b> vs <strong> (bold vs strong emphasis)

What each option means (and which is correct)

OptionTagValid HTML element?Bold result
(i)<b>YesBold (stylistic offset)
(ii)<bold>NoNot a recognized element; does not reliably create bold text
(iii)<bb>NoNot a recognized element; does not reliably create bold text
(iv)<bld>NoNot a recognized element; does not reliably create bold text

Correct answer: (i) <b>.

Why the other tags are wrong: HTML element names are fixed. Unknown tags are not part of the HTML language definition, so they don’t automatically get the browser’s built-in “bold” behavior. (Valid element behavior is defined by the spec and implemented by browsers.)

Pro Tip: Prefer semantic emphasis

If the text is important (not just visually thick), use <strong> rather than <b>; it communicates importance to assistive technologies.

Tags like <bold>, <bb>, and <bld> are not standard HTML elements, so they won’t reliably bold text.
