How does Facebook comment box work without input tag?

Question

I was inspecting facebook's comment box and it was surprising to me that there is no input tag, just a lot of nested div.

Anyone with the knowledge on how it's being implemented and why is that a better approach than a simple input tag?

here the screen screenshot of me inspecting the comment box

thank you in advance

Answer 1

Hopefully its contenteditable , Obviously with some script, validations, programming ...

 div { width: 100%; max-width: 250px; padding: 5px 10px; border: 1px solid #666; outline: 0; border-radius: 10px; } 

 <div contenteditable="true">Am I a input ???</div>
