This is a tetris game developed using HTML, CSS and Javascript.
This is a side project for me to improve my front-end dev. skills.
I used Jonhoo's code to begin and edited to implement my ideas.
You can see Jonhoo's code here. https://github.com/jonhoo/tetris-tutorial
First, I studied the original codes and made small changes (ie. replace var to let and make class)
I am not familiar with cavas and left it as is for now and concentrate my changes on other Javascript codes.
