Issue #340 • January 23, 2020
You likely are familiar with the classList.add() and classList.remove() methods that allow you to easily manipulate class names on any HTML element. More than likely you've used these with a single class, but in case you didn't know, you can add or remove multiple class names in a single line using the following syntax:
element.classList.add('one', 'two', 'three');
element.classList.remove('one', 'two', 'three');
You just have to remember that each class is an individual string value (thus the quotes) and multiple strings are separated by commas, similar to an array. So you can't do: add('one, two, three').
Here's a CodePen demo that has two buttons on the page. The buttons remove or add three class names that are used to add styles to the main content element.
If some of you didn't know that these methods accept multiple class names, it's probably because a lot of developers avoided using this feature due to lack of support in Internet Explorer (shocking, I know). So as long as you don't care about pre-Edge Microsoft browsers, you're good to use these pretty much in any project.
