How to Create Dark/Light Mode for Website using JavaScript/jQuery?
Light-on-dark color scheme, also called dark mode, is a supplemental mode that uses a color scheme in which content of a webpage is displayed on a dark background. Such a color scheme reduces the light emitted by screens and enhances readability. Switching to dark mode allows website users to move to an eye-friendly and resource-saving design whenever they want.
Steps to Create Dark/Light mode:
- Create an HTML Document.
- Create CSS for the document file as well as for dark mode.
- Add a switch/toggler to toggle between light and dark modes.
- Add functionality to the switch/toggler to toggle between light and dark mode using javascript or jQuery code.
Example 1: The following example demonstrates switching between light and dark mode using JQuery code. It basically works by using functions hasClass(), addClass(), and removeClass() method.

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Dark Mode</title> <script src= </script> <style> body{ padding:10% 3% 10% 3%; text-align:center; } img{ height:140px; width:140px; } h1{ color: #32a852; } .mode { float:right; } .change { cursor: pointer; border: 1px solid #555; border-radius: 40%; width: 20px; text-align: center; padding: 5px; margin-left: 8px; } .dark{ background-color: #222; color: #e6e6e6; } </style> </head> <body> <div class="mode"> Dark mode: <span class="change">OFF</span> </div> <div> <h1>GeeksforGeeks</h1> <p><i>A Computer Science Portal for Geeks</i></p> <h3>Light and Dark Mode</h3> <img src= <p> Click on the switch on top-right to move to dark mode. </p> </div> <script> $( ".change" ).on("click", function() { if( $( "body" ).hasClass( "dark" )) { $( "body" ).removeClass( "dark" ); $( ".change" ).text( "OFF" ); } else { $( "body" ).addClass( "dark" ); $( ".change" ).text( "ON" ); } }); </script> </body> </html> |
