Embed reactions and ratings

1. Make a widget

On Widgets, choose reactions, ratings or both and pick the symbols. You get a widget id and an edit token — keep the token, it is how you change the widget later.

2. Paste it into your page

The script once per page, then a placeholder wherever a widget should appear:

<script async src="https://millirec.com/embed/millirec-widget.js"></script>
<div data-millirec="reactions" data-widget="YOUR-ID" data-target="this-page"></div>
<div data-millirec="ratings" data-widget="YOUR-ID" data-target="this-page"></div>

3. Show the totals

data-target names what is being rated, so one widget serves many pages. Totals without a drawing pad:

<div data-millirec="reactions-count" data-widget="YOUR-ID" data-target="this-page"></div>
<div data-millirec="rating-average" data-widget="YOUR-ID" data-target="this-page"></div>

Or a badge with no script, for READMEs and emails:

<img src="https://millirec.com/badge/YOUR-ID/this-page.svg?type=rating" alt="rating">

The drawing is recognized on the visitor's device; only the vote reaches the server, once per visitor, with no account. More in Help →
