Freeze Scroll

This script provides a cross-browser way of preventing scroll on the body element. A common use case for this is when a modal window is open. Without this script, it’s easy for users to unknowingly scroll the page behind the modal and be disoriented when it’s closed.

Inspired by https://benfrain.com/preventing-body-scroll-for-modals-in-ios/

Note: Once Safari and iOS Safari support the “touch-action” CSS property (caniuse.com), we can simply toggle a class that adds the following:

  .js-no-scroll,
  .js-no-scroll body {
    overflow: hidden;
    touch-action: none;
  }

  /* Create class to allow scrolling on certain elements, like modal windows */
  .allow-scroll { touch-action: auto !important; }

Install

yarn add @threespot/freeze-scroll

Usage

import scroll from "@threespot/freeze-scroll";

// Disable scrolling
scroll.freeze();

// Enable scrolling
scroll.unfreeze();
