HTML Formatting tags text ko visually style karne ke liye use hote hain. Inme <b> (bold), <i> (italic), <u> (underline), <strong> (important text), <em> (emphasized text), <mark> (highlighted), <sub> (subscript), <sup> (superscript), <small>, aur <del> (deleted text) shamil hain. Ye tags content ko readable aur attractive banate hain bina CSS use kiye.
