Copy paste the drawing
If you want to use the drawing on your own site, copy paste this code into your HTML file:
It contains everything you need, but you need to put it into a parent element with a specified height and width.
You can also adjust the ".grid-container" style to specify it's size.
If you paste this into an empty html file, you only need to add an extra style specifying body, html { height: 100%; }
to make it fill the screen.
