Full Width Mega Menu not working when I add width:100%

Hi I am trying to design an Header with Mega Menu using HTML and custom CSS. I tried to set mega menu to full width by applying width:100% to it but doesn’t work.

This is my HTML code

<html lang="en">

I tried to give .mega-menu width:100% but it doesn’t cover full width. I tried width:1920px I still doesn’t shift to full width, Is there any other way to do it?
