The fresh new ARIA requirements facts eight commitment characteristics. Half dozen among these, aria-activedescendant , aria-regulation , aria-describedby , aria-labelledby , and you will aria-owns , get a mention of the multiple components generate good fresh link ranging from aspects on the internet web page. The real difference in for each and every affairs is what one link function and exactly how it is supplied to people.
