http://www.w3.org/Bugs/Public/show_bug.cgi?id=13999 --- Comment #3 from Marat Tanalin (tanalin.com) <mtanalin@yandex.ru> 2011-09-01 21:11:37 UTC --- (In reply to comment #1) > The performance of classList is an implementation detail. There's no > particular reason for it to be slower. One of major reasons is that consequent adding classes one by one causes multiple rendering-reflows. (Each reflow is quite time-expensive operation.) Opposite to this, adding multiple classes at once causes only one reflow. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
