maybe you could put the license information on that page! (The github page says it is MIT License for those who wonder)
btw the french flag is backwards (Blue - White - Red is the good one)
EDIT: Thanks for the flag fix benjamin!
Something that could further ease the color customization would be to use currentColor [1] on the border colors, allowing the customization to be made simply by changing the "color" attribute of the element.

I'll make sure to add license info to that demo/download page. Thanks again, a huge help!
Just an fyi :)
So, Belgium should be 13:15 (https://flagspot.net/flags/be.html, for US flags 10:19 seems best for all uses (https://flagspot.net/flags/us-size.html#prop), etc.
But that certainly is just a fyi :)
