Video 100% width and height

Question

I have a video, and I want it to FILL 100% of the width, and 100% of the height. And keep the aspect ratio.

Is it possible that it at least fills 100% for both? And

I am new into all of this. Maybe you can just add/change this HTML code. Without need for CSS. It worked for me :)

width="100%" height="height"
