Whats the use of subscription and forrmatting and deleting text?

Question

plz help me out

Answer 1

Did you mean subscript text and deleted text? If so, then a subscript text is a smaller text that appends at lower right of a normal text. Meanwhile, deleted text indicates text with a stroke on it. To understand these, try to type the following code in your code playground or any text editor in your computer, and then run.

1. Subscript text
<p>The chemical formula of water is H₂O.</p>

2. Deleted text
<p>My favourite colour is <del>blue</del> green.</p>

Hope that answers your question. ☺
