normalize.css v6.0.0 doesn't set body to margin 0, the method suggested to resolve Margin Collapsing doesn't work
I downloaded the project files and develop in Sublime Text. While the Normalize.css used in the course was earlier version, the one I used was latest version, and surprisingly it doesn't set body to margin: 0. That's why there is still gap even after I applied two methods (1. set h1 to margin-top: 0, 2. set main-header to padding: 1em) suggested in the course. I tried to find what was problem and compared two versions of Normalize.css and found out it is because the latest one doesn't set body to margin: 0. I wonder what's the use to have the latest version of Normalize.css if it is not better than the previous version?
