Advantage of styling with CSS classes in JavaScript
Using classes instead of changing styles directly has another benefit. With a slight movement of the hand, you can make the styles of the elements toggle.
For example, you can make it so that when
you first click on a paragraph, it will be
painted in a certain color, and when you
click again, it will return to its original
color. To do this, you just need to change
the add method to the
toggle method:
let elems = document.querySelectorAll('p');
for (let elem of elems) {
elem.addEventListener('click', function() {
this.classList.toggle('colored');
});
}
Modify the previous task so that pressing the button again cancels the action of this button.
