what is an inserted and deleted text

Answer 1

They are stylized text formats, like bold or italicized. Inserted text just has an underline so it looks like it was filling in a blank, and deleted text has a line struck through it, making it seem like it should be ignored, or was written previously as a mistake. I hope this helps!

Answer 2

<del>blue</del>
<ins>read</ins>
just use above tag u will understand the concept.

Answer 3

Deleted text means a text or line of text that there is an error, and you need to make changes. So, you have to do it this way: <del>fuck</del>
<ins>lovemaking</ins>
