b Element

 

Module

The b element is an inline element declared by the XHTML 1.1 Presentation Module (Inline Presentation)

Elements in the Presentation Module are:
big | small | sub | sup | i | b | tt (Inline Presentation Support Module)
hr (Block Presentation Support Module)

Description

The b element indicates that a section of text is to be rendered in bold face.

In many instances, the use of this element is discouraged in favour of a more semantically informative element, which also has meaning in non-visual browsers. For instance, b would in most cases be better substituted by strong unless the bold facing has only visual significance and is not meant to place any additional emphasis upon the text. However, if it's only for visual effect, then the bold-facing would be better controlled using CSS, so that content and presentation are well separated; personally I would not use the b element, but instead the CSS declaration font-style:bold.

See also the i element.
