Font Size

Astro UXDS font size tokens define the font size of text styles and elements. The design tokens are based on a t-shirt sizing system where the font-size-base token equals 1 rem (16 px by default), and font sizes are either smaller (sm, xs) or larger (lg, xl, 2xl, 3xl, 4xl, 5xl, 6xl) than the base. For reference, the P body text style uses the font-size-base token to set the font size.

Spacing

Astro UXDS spacing tokens use increments of four to define all dimensions, padding, and margins for components, containers, grids, and other UI elements. The design tokens are based on a 4 px system where 1 token step equals .25 rem, which equals 4 px by default. For example, the spacing-4 token equals 1 rem (16 px by default).

When building components, Astro UXDS uses the border-collapse method for sizing. In this method the borders overlap the padding within a component, as opposed to the box model method where the borders are added in addition to the padding. So in Astro UXDS, a component with 8 px padding and 2 px border would only have 8 px of spacing.

Line Height

Astro UXDS line height tokens use increments of four to define the spacing and line height of text styles and elements. The design tokens are based on a t-shirt sizing system where the line-height-base token equals 1.5 rem (24 px by default), and line heights are either smaller (sm, xs, 2xs) or larger (lg, xl, 2xl, 3xl, 4xl) than the base. For reference, the P body text style uses the line-height-base token to set the line height.
