The HTML<b> tag is used to highlight in bold that part of the text, which we want to make more obvious for the user. The <b> tag only highlights the part of the text, it has no semantic load (including for search engines).
Avoid using the <b> tag for titles and headings.Instead, you can use the <h1> - <h6> tags. It’s preferable to use this tag for marking keywords, product names or other spans of the text.
Syntax
The <b> tag comes in pairs. The content is written between the opening (<b>) and closing (</b>) tags.
Example of the HTML <b> tag:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document </title>
</head>
<body>
<p><b>This section of the text </b> has been extracted in bold,</p>
</body>
</html>
Result
The appearance of the content of the <b> container is defined by default, but the bold style can be changed by the help of CSS.
The CSS font-weight property also can be used to set bold text.
Example of the font-weight property for making the text bold:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document </title>
<style>
.bold-text {
font-weight: 700;
}
</style>
</head>
<body>
<p>
<span class="bold-text">This section of the text </span>
has been extracted in bold.
</p>
</body>
</html>
<b> vs <strong>
Both the <b> and <strong> elements render the text in a bold typeface. The difference between them is that the <strong> tag stands for a text of a certain importance, but the <b> tag contain any information about the text. However, it’s better to avoid the <b> tag. Instead, you can use the "bold" value of the CSS font-weight property.
Attributes
The <b> tag supports the Global Attributes and the Event Attributes.
