The Web VS Dat

The W3C website is a great resource, the section on ARIA](https://www.w3.org/WAI/ARIA/apg/) and as others have pointed out the patterns section is great and includes examples. Source: about 1 year ago

I copied that directly into the validator at w3.org and it showed no errors. https://validator.w3.org/nu is what you're using, yes? Source: about 1 year ago

Time to start Googling! Those are all solvable things that you can fix. The last ones in black are strange though... I have no idea what the reference to w3.org is for. Source: over 1 year ago

Google tells me some pages on my website have mobile usability errors - detailed results on GSC show 45 of 75 resources couldn't be loaded, many are apparently script and stylesheet issues to do with the theme and some plugins. The affected pages also load very slowly on GTMetrix. I turned on minify html, css and js on my caching plugin but it didn't seem to help. I did a Validate CSS check using a tool on w3.org...

Depending on what prompted this issue, there are a myriad of resolutions. If it's your SSL certificate then you simply need to get that registered and compliant. If it's because of bad coding then you can check out https://w3.org to test your code and fix it. Otherwise, you could always hire or consult a web developer. Source: over 1 year ago

Yes there are some really interesting projects, also in the ML replicability space. One really nice approach is the DAT project [1]. The protocol [2] looks pretty sensible and useful. Unfortunately, the tooling has been in such a state of permanent flux (i.e. Perpetual deprecation) that I've never bothered to invest much time.
