How can i use bookmark tag. Tell me about bookmark tag

Question

tell me syntax of bookmark tag

Answer 1

You probably mean internal links:
https://www.w3schools.com/html/html_links.asp (section "HTML Links - Create a Bookmark")

First, you must have an element with an Id:
<div id="mybookmark">
<p>I wanna jump into this paragraph.</p>
</div>

Then, in the same HTML page, you write an anchor tag, linking to "#" + the previous id:
<a href="#mybookmark">Go there!</a>
