When working with web content, there are times when you want to show that something has been added or inserted into a document. Instead of just writing the new text, HTML gives you a way to clearly show changes.
That is where the <ins> tag comes in.
The <ins> tag is used to represent inserted text. Browsers usually display this text with an underline, making it easy for readers to see what has been added.
In this guide, you will learn what the <ins> tag is, how it works, when to use it, and how to use it correctly in real-world websites. The explanation is simple and easy to follow.
Understanding the <ins> Tag

It helps readers understand what content is new or updated.
Basic Syntax
The <ins> tag has an opening and closing tag.
Example:

Anything inside the <ins> tag will appear underlined in most browsers.
Example Inside a Paragraph

This shows that “Wednesday” is the newly added or updated information.

What the <ins> Tag Means
The <ins> tag is not just for styling.
It tells browsers and users:
👉 “This content has been added or updated.”
This makes it a semantic HTML tag, meaning it adds meaning to the content.
Why the <ins> Tag Is Important
Using the <ins> tag helps:
- Show updates clearly
- Track content changes

Instead of hiding edits, it shows what has been added.

<ins> Tag vs <u> Tag

Common Mistakes Beginners Make

Is the <ins> Tag Still Used Today?

Even with CSS available, <ins> is important because it provides meaning, not just style.
The <ins> tag in HTML is used to show that text has been added or updated. It usually displays text with an underline, helping readers quickly notice new content.
It is commonly used with the <del> tag to show changes clearly, such as replacing old text with new text. This makes content more transparent and easier to understand.
While CSS can also underline text, the <ins> tag is better when the goal is to show meaningful updates in a document.
By using the <ins> tag correctly, you can make your web pages clearer, more organized, and easier for users to follow.
