Create Toggle Button in HTML CSS & JavaScript

Hello! I hope you’re doing well and working on great projects. Today, I want to share an interesting project with you: an Animated Toggle Button. You will learn how to create this button using HTML, CSS, and JavaScript. What makes this toggle button special is its morphism style, which adds charm compared to a regular toggle button.

This code creates a Animated toggle button that switches between light and dark mode by adding or removing the ‘dark’ class on the body element. The toggle button has a circle that smoothly transitions to indicate the mode, and the background of the body also smoothly transitions for a seamless experience.

I am using morphism effects, the button and background have a beautiful transition that adds a touch of elegance to the toggle switch. This type of toggle button can be used in various websites or applications, especially those that may require a light and dark mode for better accessibility or just a different design option for the user.

Animate Toggle Button

To create a toggle button using HTML, CSS, and JavaScript, you need to make two files: one HTML file and one CSS file. After you create these files, you can copy and paste the provided code into them. You can also copy all the source code.

HTML:

A simple toggle button inside a container div.
The button has a circle that will slide left and right to indicate light/dark mode.

CSS:

Body transitions between light and dark backgrounds using the .dark class.
The .toggle button changes the background colour in dark mode.
The .toggle-circle slides left or right when switching modes, using a smooth transition.
The styling includes a morphism effect for the background, with a blur and soft shadow, making it visually appealing.
