Tailwind

Design Tokens

The Skeleton Tailwind plugin provides a set of utility classes that adjust to your theme settings.

Source Page Source

Skeleton utilizes a simple but powerful design token system to implement theme settings in elements and components. These represent the defaults for most elements and components, which means they auto-adapt based on your theme with minimal configuration out of the box. Best of all you can use these within your custom components as well!

We recommend this conference talk by Brad Frost if you would like to learn more about the design token concept.

Theme Flow

Below is a visualization of how Skeleton uses your theme to control your UI. We start with your theme's CSS variables, then construct design token classes based on these variables, next components utilize these design token classes, then finally you construct your pages with sets of elements and components.

Color Pairing Chart

Below is a visualization of color pairings in Skeleton. This is how we balance light and dark mode for your themes in practice. For example, the surface color swatch 50 is the lightest available color, so we utilize that for your light theme background color. While swatch 900 is the darkest, so vice versa. These two colors form a pair. We then generate design token classes for .bg-surface-50-900-token and bg-surface-900-50-token that automaticallys switch between these in light/dark mode respectively.
