The <b>
tag in HTML is used to apply bold formatting to text. It's a presentational element, meaning it's used to define how text should be displayed rather than the structure or meaning of the text. Here's the basic syntax:
<b>This text will be bold.</b>
When rendered in a web browser, text enclosed within <b>
tags will typically appear bold. However, it's important to note that the <b>
tag is considered a deprecated element in HTML5, as it doesn't convey any semantic meaning about the text it encloses.
Instead of using the <b>
tag for bold text, it's generally recommended to use the <strong>
tag, which carries semantic importance, indicating that the text is of strong importance or emphasis. The <strong>
tag is typically styled to appear bold by default, but its primary purpose is to convey meaning rather than presentation.
Here's an example of using the <strong>
tag:
<strong>This text is strongly emphasized.</strong>
Both <b>
and <strong>
tags can be styled further using CSS to adjust their appearance according to your design preferences. However, when possible, it's best to prioritize semantic HTML elements like <strong>
over presentational ones like <b>
, as they provide clearer structure and meaning to your content, which is beneficial for accessibility and SEO.
Syntax and Attributes
The <b>
tag in HTML is a formatting element used to apply bold styling to text. It doesn't carry any semantic meaning and is primarily used for presentational purposes. Here's the syntax and a list of attributes:
Syntax:
<b>Text content</b>
The <b>
tag is an inline element, which means it does not create a new block-level element but rather applies the bold styling to the text within it.
Attributes: The <b>
tag does not have any specific attributes of its own. However, it supports global attributes that are common to most HTML elements. These attributes include class
, id
, style
, title
, etc. Global attributes provide additional information about the element or define its behavior.
Here's an example demonstrating the usage of the <b>
tag with a global attribute:
<b id="boldText" class="important" style="color: red;">Bold Text</b>
In this example:
- The
id
attribute assigns an identifier to the<b>
element, which can be used for scripting or styling purposes. - The
class
attribute assigns one or more classes to the element, allowing it to be styled or targeted with CSS rules. - The
style
attribute applies inline CSS styles to the element, in this case, changing the text color to red.
These attributes can be used to enhance the styling or behavior of the <b>
tag, although it's important to remember that the primary purpose of the <b>
tag is for presentational styling rather than semantic markup. For semantic emphasis, consider using the <strong>
tag instead, which conveys meaning in addition to applying bold styling.
Accessibility Considerations
When using the <b>
tag in HTML for styling text to appear bold, it's essential to consider accessibility to ensure that the content remains perceivable and understandable for all users. Here are some accessibility considerations:
Semantics vs. Presentation: The <b>
tag is a presentational element and does not convey any semantic meaning. Therefore, it should be used judiciously, especially in contexts where semantic markup would be more appropriate. Consider whether the text being styled as bold carries any semantic importance. If it does, consider using the <strong>
tag instead.
Text Alternatives: Ensure that text styled with the <b>
tag has appropriate text alternatives, especially for screen reader users. Screen readers may announce bold text differently, so ensure that the meaning is preserved and conveyed effectively through alternative text or surrounding context.
Contrast and Readability: Bold text should maintain sufficient contrast with its background for readability. Ensure that the chosen font color and background color provide enough contrast for users with low vision or color vision deficiencies to perceive the text easily.
Styling Overrides: If you're using CSS to style <b>
elements, ensure that the styling doesn't interfere with users' ability to perceive or interact with the content. Avoid overriding user preferences, such as browser settings for font size or color, unless absolutely necessary.
Testing with Assistive Technologies: Test your web content containing <b>
elements with screen readers and other assistive technologies to ensure that the bold text is conveyed effectively and that users can access and understand the content as intended.
Progressive Enhancement: Ensure that the meaning and structure of your content are preserved even if CSS or JavaScript is disabled. While the <b>
tag can enhance the visual presentation of text, it should not be relied upon solely for conveying meaning or structure.
By considering these accessibility guidelines, you can ensure that your use of the <b>
tag enhances the readability and usability of your content for all users, including those with disabilities.

Semantic Meaning: The <b>
tag carries semantic meaning, indicating that the enclosed text should be stylistically bold. However, it's important to consider using the <strong>
tag instead when the text represents important or emphasized content semantically.
Best Practices:
Accessibility Testing: Perform thorough accessibility testing to ensure that bolded text is properly interpreted and presented by screen readers and other assistive technologies. Verify that the content maintains semantic meaning and readability for users with disabilities.
Styling Consistency: Maintain consistent styling for <b>
elements across different browsers and devices to ensure a uniform user experience. Test the appearance of bolded text in various scenarios to identify and address any compatibility issues.
Use of <strong>
for Emphasis: Consider using the <strong>
tag instead of <b>
when the bolded text represents important or emphasized content semantically. This enhances accessibility by conveying the importance or emphasis of the text to users and assistive technologies.
In summary, the <b>
HTML tag enjoys good support across modern web browsers and is compatible with mobile browsers and assistive technologies. By following best practices and ensuring consistent styling, developers can create accessible and user-friendly bolded text on the web.
