Deleting padding

Hi,

I’m relatively new to wordpress with some experience in CSS. If you look at the home page on the website (www.kashdev.com), there is a large white bar that stretches across. I used the inspector tool and found the code and found that the bar is padding but when I try to get rid of it or even change the color, no changes happen in the code. Ive gone into editor and tried changing it manually but whenever I inspect it, it says the code never changed. Can someone please help? I need this for work hahaha
