With their tagline "Teaching the world how to code," Codecademy showcases interactive learning on their website. You may need to sign up to enjoy these free courses. I already did! Like in a virtual world, we need to grind and earn EXP (as in experience) in our jobs or skills. This is a great opportunity because it is free!
The HTML & CSS courses already have more than 4.5 million students!
I highly recommend this website! :) Come on and learn how to code!
