Hey Chris! First of all, thank you for the help and content you put out to help everyone. I am a fresher graduate in electrical looking to start working in the IT sector since things arent working out good in my own job market. I started an internship in an IT firm and I am really thankful for all the material provided here. It’s really helping me learn and grow the technologies from ground up ( HTML, CSS, JS). I just want you to check my code once and let me know what can i do better to optimize it or some tips from your side. Thanks again!
PS. The readings are wrong for the last 4-5 planets. Sorry!
