So what you're saying is W3Schools should not be called out for posting misinformation?

A the risk of being tarred and feathered for pedantic behavior, the W3Schools doesn't post misinformation. They posted information that was accurate at the time, and then let is sit up there for 5-8 years as the state of the art improved.

I never said anything about the accuracy of w3schools. And as the person below has commented, the issue is more or less about out dated information.
