What is the primary function of the <strong> tag?

The tag is primarily used to indicate strong importance of the enclosed text. When text is wrapped in this tag, it not only conveys semantic meaning, emphasizing that the content is of greater significance, but it is also typically rendered in bold by default in most web browsers. This visual representation helps enhance the reading experience by allowing users to easily identify and focus on the most critical parts of the text.

In web accessibility, using the tag can be beneficial as screen readers often announce this emphasis, allowing visually impaired users to better discern the importance of the information. Overall, the tag is an essential tool for both conveying meaning and improving user experience in web design.
