How to do comment box?

Question

i like to do comment box and if its comment the comment goes on the page.

Answer 1

I assume you mean like an input box? You use the textarea tag within a form.

<form action="comments.php" id="comment-form">
<textarea rows="5" cols="100"></textarea>
</form>

Test it out in the code playground.

However, to actually use that information and post it on a page requires knowledge of PHP and also preferably JavaScript (that is, in a typical web page - many other languages can be used, such as Python). If you're still learning HTML, I suggest you gain a better knowledge of front-end development (HTML/CSS/JS) before moving on the backend.
