Introduction

In 2026, users expect websites to adapt to their preferences. One of the most demanded features is the ability to add light mode and dark mode in WordPress. Dark mode reduces eye strain, saves battery on mobile devices, and gives your website a modern look. Light mode, on the other hand, remains ideal for readability in bright environments.

If your website does not support theme switching, you may lose engagement and accessibility scores. In this guide, you will learn how to add light mode and dark mode in WordPress using plugins, custom CSS, and Elementor — without breaking your design or SEO.

Method 2 – Add Light Mode and Dark Mode in WordPress with Custom CSS

If you want full control without plugins, you can create your own mode switcher.

Step 1 – Add Toggle Button

Insert this HTML in header or footer:

<button id="theme-toggle">Switch Mode</button>

Step 2 – Add CSS Variables

:root {
 --bg-color: #ffffff;
 --text-color: #000000;
}

.dark-mode {
 --bg-color: #121212;
 --text-color: #ffffff;
}

body {
 background: var(--bg-color);
 color: var(--text-color);
}

Step 3 – Add JavaScript

document.getElementById("theme-toggle").onclick = function(){
 document.body.classList.toggle("dark-mode");
}

Now your website supports both modes without heavy plugins.

Method 3 – Add Light Mode and Dark Mode in Elementor

If you use Elementor in 2026, you can integrate mode switching easily.

1. Create two global color sets
2. Use CSS classes for sections
3. Connect toggle button with custom attributes
4. Save as global header

Elementor Pro users can even create automatic mode detection based on system preference.

Automatic System-Based Dark Mode (2026 Trend)

Modern browsers allow detecting user preference.

Add this CSS:

@media (prefers-color-scheme: dark) {
 body {
   background:#121212;
   color:#ffffff;
 }
}

This automatically enables dark mode if the user device is in dark theme — a smart 2026 approach.
