Tailwind CSS Dark Mode
Installation
npm install tailwindcss-dark-mode --save-dev
Add the plugin to the plugins array in your Tailwind configuration.
plugins: Usage
Styles generated by this plugin are only used if the selector is applied to the <html> element. How you do that is up to you. prefers-dark.js is provided as an option, which is a simple script that enables dark mode based on the user's system theme.
Available Variants
Variants for dark mode are based on Tailwind's own variants...
darkdark-hoverdark-focusdark-activedark-disableddark-group-hoverdark-focus-withindark-evendark-odddark-placeholder
... and are used in the same way.
My eyes are grateful. Learn more Enabling Variants
As with existing variants such as hover and focus, variants for dark mode must be enabled in your Tailwind configuration for any utilities that need them.
variants: backgroundColor: 'dark' 'dark-hover' 'dark-group-hover' 'dark-even' 'dark-odd' borderColor: 'dark' 'dark-disabled' 'dark-focus' 'dark-focus-within' textColor: 'dark' 'dark-hover' 'dark-active' 'dark-placeholder'Please note: This is only a simple demonstration for how dark variants are enabled and how they could be used. The variants provided by this plugin are not replacements for Tailwind's own variants, they are to be used in addition to them. For example, anywhere you would enable dark-hover, you should also enable hover.
Changing the Selector
By default, .mode-dark is used as the selector for dark mode. You can change this by adding the darkSelector key to the theme section in your Tailwind configuration.
theme: darkSelector: '.mode-dark' Don't forget to also change the selector in prefers-dark.js if you are using it.
PurgeCSS
If you are using PurgeCSS, you should either add the selector to the whitelist array...
whitelist: 'mode-dark'... or add prefers-dark.js to the content array.
content: '**/*.js' './node_modules/tailwindcss-dark-mode/prefers-dark.js' './or/your/own/prefers-dark.js'Otherwise, PurgeCSS will assume that any classes related to dark mode should be removed, as the selector is only applied when the page is loaded.
