What Are CSS Custom Properties?

CSS custom properties (variables) let you define reusable values once with --variable-name: value and reference them anywhere with var(--variable-name). Defining your color palette as variables makes global theme changes a single-line edit.

Generated Variable Scale

Variable	Description
--primary-50	Lightest tint (near white)
--primary-100 to 400	Light tints
--primary-500	Base color
--primary-600 to 900	Dark shades

Best Practices

Declare your variables in :root for global access. Use semantic aliases like --color-primary pointing to var(--primary-500) so component styles stay readable even as the palette evolves.

'Is my data uploaded to a server?', 'a' => 'No. Everything runs locally in your browser using JavaScript. Your data never leaves your device.'], ['q' => 'Why does the scale go 50, 100, 200 ... 900?', 'a' => 'This naming follows Tailwind CSS and Material Design conventions, making it easy to integrate these variables into projects that already use those systems.'], ]" />
