Within the intricate tapestry of HTML elements, the <data> tag stands out as a versatile tool for embedding machine-readable annotations within your content.

In this comprehensive guide, we will explore the nuances of the HTML <data> tag and how you can leverage its capabilities.

🤔 What is <data> Tag?

💡 Syntax
