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: over 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

Hello, I have a question about sites like DeHashed.com, snusbase.com and intelx.io. Source: over 1 year ago

So if that is true, how could I go to the sites like https://intelx.io , https://dehashed.com/ ,https://snusbase.com/ and type email address that has been in a breach and obtain possible password and username sometimes for free, and sometimes for a couple of bucks? If what the OP of the linked post says is true. These platforms should not be legal, or am I missing something? Source: over 2 years ago

Usually it depends on where it will end up, you'll have to look through multiple different companies that pay to collect this information. Haveibeenpwned is a really great indicator to see the basics of where your information has been leaked through, but depending on the breach I'd recommend http://snusbase.com to get more details about what was contained in those databases.

My favorites are theses 3, and are the most updated & fastest updated. - https://pwndb2am4tzkvold.onion.ws/ - https://snusbase.com/ - Dehashed.com (very nice but not free :/). Source: about 3 years ago
