Ember Fast Marquee

Ember Fast Marquee is a lightweight ember component that utilizes the power of CSS animations to create silky smooth marquees.

Inspired by React Fast Marquee

Differences from React Fast Marquee

• Automatically duplicates content as many times as necessary
• Use @fillRow={{true}} to fill any left over white space if desired
• 1 transform3d animation per marquee

Compatibility

• Ember.js v3.24 or above
• Embroider or ember-auto-import v2

Installation

ember install ember-fast-marquee

Usage

To use the component, first you need to import marquee.css into your application somehow.

If you are using embroider simply import the css into your application

// application.js
import "ember-fast-marquee/marquee.css";

Or import into your css as your would other third party CSS eg.

/* app.css */
@import "node_modules/ember-fast-marquee/marquee.css";

Then wrap the <Marquee> component around any component or text you'd like to slide.

<Marquee>
  I can be a component, multiple components, plain html or just some text.
</Marquee>
