Smooth parallax scrolling effect for background images using the
Jarallax plugin from nk-o.


  • Install this module using the official Backdrop CMS instructions.

  • Visit the configuration page under Administration > Configuration > User
    Interface > Jarallax

  • Adjust the default settings and add the elements that you wish to add the
    parallax effect to. The parameters follow the options
    provided in the Jarallax library.


Currently you'll need to add a min-height or aspect-ratio or padding in
the CSS settings for the elements you apply Jarallax to, otherwise they will
collapse when it is applied and will not be visible. Follow this issue.


Long term vision includes:

  • Implementing more of the basic options into the admin UI.
  • Implementing Jarallax element and Youtube/Vimeo background video options.
  • Adding a modified hero block that lets you add image, text, etc. and
    configure the parallax effect all in one place.


Please add and review usage guidelines in the Wiki.
