Does that mean getting HTML/CSS vcertificates from W3Schools makes you a certified HTML/CSS fool??????
Yes actually, it does -- because their certificates mean exactly two things.
They aren't qualified to be handing out certificates in a blasted thing; they are not a recognized educational institution, they are not associated in any way with any of the bodies responsible for making the specifications... and you know what that means?
Their "certificates" are one big giant sleazeball SCAM, worth less than a sheet of bog roll.
Though to be fair, I say the same thing about real college degrees in IT, particularly web development... YMMV
