Where do I code?

Hello, I am very new to the coding world. I am currently working on my Responsive Web Design Certification which I am enjoying! I want to begin working on my own projects but I don’t know where to start or what website I should use to make websites using HTML. Does anyone have any suggestions on free websites where I can put my new coding skills to work? It would be greatly appreciated to hear what you guys use! Thank You!

I hope the progress is good. The internet offers some code editors where you can write your code, for big projects, I like using VS code, for smaller projects or when I want to try something out, I use replit or code pen. You can check the available code editors and choose the one you prefer.

Thank you so much I will definitely look into those!
