The <strong> Tag in HTML


The <strong> tag in HTML is used to define text that has strong importance within a document. It’s a way to emphasize certain words or phrases, making them stand out in the content. While visually, it often appears bold, the semantic meaning behind the <strong> tag is what sets it apart from simply using the <b> tag for bold text.


Here’s an example of how you can use the <strong> tag to emphasize a crucial part of a sentence:

<p>The new product launch is <strong>tomorrow</strong>, and we are all excited about it!</p>

Most browsers will display the <strong> element with the following default CSS setting:

strong {
  font-weight: bold;

This CSS rule makes the text inside the <strong> tag appears bold, but remember, the semantic importance of the text is the primary reason for using this tag. You can also use HTML <b> tag.

Event Attributes

You can also use Event Attributes with the <strong> tag to define specific behaviours in response to user actions, such as clicks or mouse movements.


The <strong> tag is a valuable tool in HTML for emphasizing text with strong importance. It’s more than just a visual cue; it conveys a semantic meaning that can be essential for accessibility and understanding the context of the content.
