<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.
- Do not confuse the
<b>element with 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
<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.

- Tag omission None, both the starting and ending tag are mandatory.
