Treehouse Guest TeacherThe classList
property is a collection, like an array. It contains all the individual className
s of a particular DOM element. So you can use the .remove()
method on the classList
property to remove a single className
from a DOM element, like so:
element.classList.remove('one-class-name');
The className
property is a string that contains all the individual className
s of a DOM element. Strings are immutable, so you can't use .remove()
on it.
If you want to reset all the classNmaes
of a DOM element, you can do this:
element.className = 'new-class-name;
But that will remove all the classNames of an element, which can break styles or functionality if the CSS or JS relies on another className belonging to the element. So going with classList.remove or classList.add is usually a safer choice.
