HTML <b> tag

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).

In HTML 5 it’s recommended to use the <b> tag only as a last resort, when it is not possible to use other tags.

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.
