Responsive News homepage using HTML, CSS, and JavaScript

I had so much fun solving this challenge. I was lazy to learn about responsive mobile menu feature using JavaScript. I am proud to have figured it out on my own. Yet it was my first trial so any tips and feedback on that specific feature would be appreciated! Another thing I was not very confident about was using Bootstrap and Flex at the same time. It does get complicated from time to time and I learned that it's very important to plan things ahead before coding - looking at the challenge and writing down the sequence of each block (or session) on my note helped clearing it up for myself before starting. Anyways, anyone who's reviewing my work, thank you very much for spending your time on it, and happy coding! :>
