Before my immersive full stack software development course begins on Monday, I've built a chess clock using the basic languages of the web - HTML CSS and Javascript! Though I'm still working out some bugs, it's mobile and desktop friendly. Check out my work at this link and comment what you think or how you'd improve if your a front end developer!
