Question

Please run snippet in fullscreen mode, then you see cubes are too big, I want to make it smaller:

I have change size on root but it make a space between cubes, how can I make it small without make any space between?

:root {
  --hue: 185;
  --radius: 5.5;
  --size: 4;
}

I change it to:

:root {
  --hue: 185;
  --radius: 5.5;
  --size: 1;
}

Just use this for example:

:root {
  --hue: 185;
  --radius: 4;
  --size: 3;
}

or

:root {
  --hue: 185;
  --radius: 3;
  --size: 2;
}

or even

:root {
  --hue: 185;
  --radius: 1.5;
  --size: 1;
}

It will also work when the --radius is 1.5 more than the --size (This works for every size)

For example:

:root {
  --hue: 185;
  --radius: 25.5; /* 1.5 more than the size */
  --size: 24;
}
