Bolt Background

Background Component in Bolt

Background can be added to any container. Part of the Bolt “Components” CSS framework that powers the Bolt Design System.

Install via NPM
npm install @bolt/components-background

Description

Background allows Bolt to set an image inside of bands.

  • Can set an image inside the band
  • Can set background shapes
  • Can set focus on the left
  • Can set focus on the right
  • Can set light, medium, or heavy opacity
  • Can set a left, right, or center gradient

We recommend a max-width of 2880px for full-bleed background images. This recommendation takes into consideration the common HD screen resolution of 1920x1080 and multiplies 1920 by 1.5.

  {% include "@bolt-components-background/background.twig" with {
  opacity: "heavy",
  fill: "gradient",
  focalPoint: {
    vertical: "center",
    horizontal: "center"
  },
  contentItems: [
    {
      pattern: "image",
      src: "/images/content/backgrounds/background-tall-4.jpg"
    }
  ]
} only %}

Note: when assigning component props as HTML attributes on a web component, make sure to use kebab-case.
