Installation
The Gutter is available on npm but the recommended usage is via unpkg unless you have advanced javascript knowledge and you know how to use a bundler.
<script src="https://unpkg.com/@thehonestscoop/gutter@latest" defer></script>
Make sure you insert it below the closing </body>
tag because it is imperative that the script runs after the rest of your page is loaded. Be wary that not all legacy browsers recognize the defer
statement.
