fwiw ... to test the site you can load and read it on a desktop and on a phone. if it also passes the validator and jslint without error or warning you are half done. It should load within 1 second on mobile (pagespeed) have zero errors on wave webaim, A+ on securityheaders.com, and full marks on webbkoll.5july.net, a proper dmarc reject entry and pass dr-dsgvo webcheck. That would be a good start. Oh, and no divs. Not allowed ...
