As I was looking for a simple but feature rich css-framework I came across W3CSS. Great job, thank you.
I have questions about development/improvement:
https://github.com/JaniRefsnes/w3css (v4.10) seems not to be up to date with downloadable versions from https://www.w3schools.com/w3css/w3css_downloads.asp (v4.13)
Could you please update?
I would like to contribute (bugfixing and a breadcrumb style). How? (As Github is not up to date, merge requests seem no good idea...). Maybe a CONTRIBUTING.md file in GitHub is a good idea.
Thank you again for this well documented, easily usable css-framework.
