The HTML <b> Element represents a span of text stylistically different from normal text, without conveying any special importance or relevance. It is typically used for keywords in a summary, product names in a review, or other spans of text whose typical presentation would be boldfaced. Another example of its use is to mark the lead sentence of each paragraph of an article.

Usage notes:
|
|
Do not confuse the <b> element with the <strong>, <em>, or <mark> elements. The <strong> element represents text of certain importance, <em> puts some emphasis on the text and the <mark> element represents text of certain relevance. The <b> element doesn't convey such special semantic information; use it only when no others fit.
|
|
Similarly, do not mark titles and headings using the <b> element. For this purpose, use the <h1> to <h6> tags. Further, stylesheets can change the default style of these elements, with the result that they are not necessarily displayed in bold.
|
|
It is a good practice to use the class attribute on the <b> in order to convey additional semantic information (for example <b class="lede"> for the first sentence in a paragraph). This eases the development of several stylings of a web document, without the need to change its HTML code.
|
|
Historically, the <b> element was meant to make text boldface. Styling information has been deprecated since HTML4, so the meaning of the <b> element has been changed.
|
|
If there is no semantic purpose on using the <b> element, using css property font-weight with bold value would be a better choice for making text bold.
