To mark inserted text in HTML, use the <ins>…</ins> tag. This is crucial in finding the differences between multiple versions of the same document. Also, use it to signify a range of text added to a document.
Example
You can try to run the following code to mark inserted text in HTML
<!DOCTYPE html> <html> <head> <title>HTML ins tag</title> </head> <body> <h1>Heading</h1> <p> This is demo text. <br> <ins>This text is inserted</ins> </p> </body> </html>
