I have nothing to do, so I used H5 to play a few small games. Of course, I am just a novice, so I just want to play with them. Don’t blame me if you are a master.
1. HTML5 web version of the black and white backgammon game code, please download the source code appendix!

Part of the front-end code:

<!DOCTYPE html>

<head>
<meta charset="UTF-8">

<style type="text/css">

overflow: hidden;
}
.text{
