Role of the href Attribute in <a>
The href attribute in the <a> (anchor) tag specifies the URL or location that the link should point to. When a user clicks the link, the browser navigates to the resource defined in href.
It defines the destination of the hyperlink (a webpage, file, email address, or part of the same page).
If href is missing, the <a> element won’t work as a link.
You can use absolute URLs (e.g., https://example.com) or relative URLs (e.g., /about.html).
Special values like mailto:someone@example.com open an email client, and tel:+123456789 initiates a phone call on supported devices.
In short: The href attribute defines the target address of a hyperlink, making the <a> tag functional.
