Variables

See how Bulma uses Sass variables to allow easy customization

Bulma has two variable files divided into 4 sections:

  1. Initial variables: where you define variables by literal value, like:
    • colors: $blue: hsl(217, 71%, 53%)
    • font sizes: $size-1: 3rem
    • dimensions: $gap: 64px
    • other values: $easing: ease-out or $radius-large: 6px
  2. Derived variables where variables are calculated from the values set in the previous file. For example, you can have:
    • Primary colors derived from the initial variables:
      • $primary: $turquoise
      • $link: $blue
      • $info: $cyan
      • $success: $green
      • $warning: $yellow
      • $danger: $red
      • $dark: $grey-darker
      • $text: $grey-dark
    • $background: $white-ter: a general background color
    • $link: $blue: the links use the primary color
    • $family-primary: $family-sans-serif: the primary font family is the sans-serif one
    • Lists and maps which are collections of already defined variables:
      • $colors: mergeColorMaps(("white": ($white, $black), "black": ($black, $white), "light": ($light, $light-invert), "dark": ($dark, $dark-invert), "primary": ($primary, $primary-invert), "link": ($link, $link-invert), "info": ($info, $info-invert), "success": ($success, $success-invert), "warning": ($warning, $warning-invert), "danger": ($danger, $danger-invert)), $custom-colors)
      • $shades: mergeColorMaps(("black-bis": $black-bis, "black-ter": $black-ter, "grey-darker": $grey-darker, "grey-dark": $grey-dark, "grey": $grey, "grey-light": $grey-light, "grey-lighter": $grey-lighter, "white-ter": $white-ter, "white-bis": $white-bis), $custom-shades)
      • $sizes: $size-1 $size-2 $size-3 $size-4 $size-5 $size-6 $size-7

To override any of these variables, just set them before importing Bulma.
