Similarly, we can add Table of Contents to our webpage. It will show all the contents covered in our blog post.

Unlike the textbook, in the webpage, we can internally link each of the element in the ToC to the webpage content. By clicking on it, we can jump to any topic.

Sometimes, it is also called a reference table.

What is Internal Link in HTML?

  • An internal link is a link which points within the webpage content itself.
  • When you click on the link anchor text, the webpage will be scrolled to the content where it is pointing.
  • Internal link starts with the “#” keyword.

HTML code Example:

Anchor for internal link:

<a href="#need">Why there is need to establish the connection to the transfer message?</a>

This link will point to

<h4 id="need">Why there is need to establish the connection to transfer message?</h4>

Here “id” value should be the same as “# link”.

When you add multiple internal links linked to subtopics in your article, it forms Table of Contents.

Best way to insert a table of contents on website is, list out all the subheading in the article as ToC. Link each list element to the subheading.

Check basic HTML tags for creating a list.

This is how it looks like.
