Darkmode.js is a lightweight vanilla JavaScript library that adds a dark-mode/night-mode toggle to any website using CSS mix-blend-mode. It provides an automatic floating widget, remembers the user's choice in localStorage, and respects the OS prefers-color-scheme setting.

Use cases

• add dark mode to a website in seconds
• drop-in night mode toggle widget for any site
• respect user's OS dark theme preference
• remember dark mode setting across visits
• programmatically toggle dark mode without a widget
• add dark theme to WordPress or Drupal site

When to choose

• you want a zero-config, copy-paste dark mode solution
• your site lacks a native dark theme and you need a quick fix
• you want a lightweight vanilla JS widget with no dependencies

When to avoid

• you need a fully designed, per-component dark theme rather than a blend-mode filter
• mix-blend-mode rendering artifacts are unacceptable for your design
• you need fine-grained theming with CSS variables or design tokens
