• easily add a toggle switch to any HTML element
• state is remembered between page loads
• works in all modern browsers
• no external dependencies - works with any framework
• fast and lightweight: 630 bytes of JavaScript

Usage

The page must load the JavaScript. It can be placed anywhere but, typically, it is loaded just before the closing </body> tag:

<script src="https://cdn.jsdelivr.net/npm/toggled.js/dist/toggled.js"></script>

The CDN URL is shown above but you can also npm i toggled.js to install via npm and use a bundler.

Add a data-toggled="NAME" attribute to any HTML element. When that element is clicked, the NAME class is added to or removed from the HTML body.

<button data-toggled="buttonsize">CLICK ME</button>

When the button is clicked for the first time, a buttonsize class is added to the HTML body. CSS or JavaScript can respond to the change, e.g. change the font size:

.buttonsize button {
  font-size: 2em;
}

The class is removed when the button is clicked for a second time and the state is retained between page loads.

Advanced options:

• Any clickable element can be used as a toggle.
• Any number of space-separated classes can be defined, e.g. data-toggled="NAME1 NAME2 NAME3".
• Set data-toggled="" to apply the element's classes, e.g. when <button class="one two" data-toggled="">button</button> is clicked, the classes one and two are toggled on the HTML body.
