The
<strong>tag is used to define important or emphasized text that carries strong semantic meaning.
Browsers typically render it in bold, but unlike the<b>tag, it indicates that the enclosed text has greater importance or urgency in the context.
It is useful for accessibility — screen readers will emphasize the text more strongly.

The <strong> tag displays text in bold, but more importantly, it conveys semantic emphasis that affects accessibility and SEO.
Notes
- The
<strong>tag is semantically meaningful, unlike<b>, which is purely visual. - Screen readers emphasize
<strong>text, improving accessibility. - It is an inline element, meaning it does not start on a new line.
- You can style
<strong>text with CSS to change its color, font weight, or background.
Conclusion
The <strong> tag is used for semantically important content that needs emphasis both visually and contextually.
It enhances readability, accessibility, and SEO — making it more meaningful than the simple <b> tag.
