How to Implement a Dark Mode Switch with Bootstrap

Mar 17, 2022 | Programming

Adding a dark mode switch to your website is like giving your visitors a cozy pair of sunglasses when the bright rays of a website are too blinding. With just a few lines of code, you can make your site more user-friendly by allowing visitors to toggle between light mode and dark mode. In this article, we’ll guide you through the process step-by-step.

Quick Start

There are several options for getting started with the Dark Mode switch:

  • Download the latest release
  • Clone the repository: git clone https://github.com/coliff/dark-mode-switch.git
  • Install with npm: npm install dark-mode-switch
  • Install with yarn: yarn add dark-mode-switch

Usage

To add a dark mode toggle, you’ll need to create a custom switch. Here’s how to set it up in Bootstrap:



Once you’ve created the toggle, edit the dark-mode.css file to suit your site’s design. The CSS included is a basic example.

How It Works

When you toggle the dark mode switch, a little magic happens—specifically, the attribute data-theme="dark" is added to the <body> tag. Think of this as flipping a light switch in a dark room; suddenly, everything looks different! You can then apply CSS styles to target the elements on your page:


css[data-theme="dark"] {
  background-color: #111 !important;
  color: #eee;
}

Browser Support

This dark mode switch works well with all browsers supported by Bootstrap 4 and Bootstrap 5.

Enabling Dark Mode in Android WebView

If you’re looking to implement this feature in an Android WebView, you’ll need to enable the DOM Storage API:


WebSettings.setDomStorageEnabled(true);

Troubleshooting Tips

If you encounter issues while implementing the dark mode switch, consider the following troubleshooting steps:

  • Ensure that the paths to your scripts and stylesheets are correct.
  • Check for conflicting CSS styles that might override your dark mode settings.
  • Use your browser’s developer tools to inspect the elements and see if the data-theme="dark" attribute is applied correctly.
