My first complete Landing page using HTML SASS and JavaScript

This took a very long time to complete!! On my first Landing page using SASS, I have followed Mobile-First Principle and BEM naming convention for SASS. I have also animated the mobile burger menu for the first time and I think it is the best part of the project. I am open to receive any feedback positive or negative. I'll use all the feedback to improve upon my skills. Thanks for taking the time and looking at my code.
