Once in an interview, the interviewer asked me how to center a div without using CSS. I was like how to do it without using CSS. I was blank for a few moments and then I answered, I can think of only one possibility that is an HTML tag.

<center>
   <div></div>
</center>

We could not use CSS property in JS also. Basically, you have to do it only in HTML, not CSS & JS.

If you have any answers please let me know in the comment.
