This is the animated corner widget I use on elidourado.com to link to my Twitter account. On hover it displays a pleasing flapping motion.
Usage is simple. Put a script tag in your HTML body wherever you want the added elements to go. Include a data attribute indicating your username.
Example:
<script src="twitter-corner-widget.js" data-username="elidourado"></script>
You can add a data-gtag attribute if you would like to include Google Analytics tracking for hover and click events on the widget.
<script src="twitter-corner-widget.js" data-username="elidourado" data-gtag></script>
By default, the widget uses #1da1f2, Twitter-brand blue, as its color. You can change it to match your brand using the data-color attribute.
<script src="twitter-corner-widget.js" data-username="elidourado" data-color="orange"></script>
