What is the HTML code for bold?

The "b" tag is used in HTML to make content appear bold. Some other tags that also display text in bold are "strong," "em," "mark" and the six heading tags.

The "strong" tag is used to represent content of importance. The "em" tag puts emphasis on the text, and the "mark" tag represents text of relevance.

For headings and titles, the tags "h1" through "h6" are used to make text bolder and larger. Typically "h1" is the largest, and the size decreases as the numbers go up, although users can customize the size of headings by using a style sheet.
