I've used frontendchecklist for a few years now and it has a collection of rules and best practices kinda like this. Unforunately it seems the website has recently been updated to embrace "ai-readiness". But the rules are still there https://frontendchecklist.io/rules/html/input-types https://frontendchecklist.io/rules/html/input-types When I build UI components from scratch I really like this site: https://component.gallery/ https://component.gallery/ It links to components across many different design systems. Many of these design systems include in-depth accessibility, i18n, etc guidelines. Some standouts in terms of documentation are Salesforce's Lightning Designs System and StackOverflow's Stacks https://www.lightningdesignsystem.com/2e1ef8501/p/99642e-carousel/b/74d5d4 https://www.lightningdesignsystem.com/2e1ef8501/p/99642e-car... https://stackoverflow.design/system/forms/checkbox https://stackoverflow.design/system/forms/checkbox
