Check out the live demo.

Features

  • Supports vertical & horizontal scrollbars.
  • Easy scrollbar configration - everything using CSS!
  • Uses MutationObserver to update scrollbar size & position.
  • Supports min-height (default 20% of viewport) to ensure scrollbar remains draggable on very long content.
  • When user has scrolled to the beginning or the end of content, Scrolly seamlessly activates scrolling of parent body by detecting if user scrolled with greater scroll inertia.

Installation

$ npm install vue-scrolly

Using vue-scrolly

First, import vue-scrolly into your Vue component.

import { Scrolly, ScrollyViewport, ScrollyBar } from 'vue-scrolly';

export default {
  // ...
  components: {
    Scrolly,
    ScrollyViewport,
    ScrollyBar
  }
}

Then, construct your div block with overlay scrollbar using scrolly component.

<scrolly class="foo" :style="{ width: '400px', height: '300px' }">
  <scrolly-viewport>
    <!-- Your contents here -->
  </scrolly>
  <scrolly-bar axis="y"></scrolly-bar>
  <scrolly-bar axis="x"></scrolly-bar>
</scrolly>

Customizing overlay scrollbar

You can customize the appearance of the overlay scrollbar using CSS overrides.

This simple example below creates custom blue overlay scrollbar:

.scrolly.foo .scrolly-bar:before {
    background: blue;
}

For complete reference, you can look at vue-scrolly's default CSS stylesheet from the main Scrolly.vue component file.
