Özet
The HTML B Element (<b>
) represents a span of text stylistically different from normal text, without a 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.
