Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

                <h1>Auto-link Hashtags Ultimate</h1>
<p>Need an answer? Search for #answer thanks to auto-link hashtags utlimate.</p>
<p>Need to ignore markdown? **#ok**.</p>
<p>Need to ignore html? href="#fine".</p>
<p>Need to support all languages? #kärlek (but, not quite because this does not work: #愛)</p>
<p><strong>In conclusion, this JavaScript will support many laguages (not all) and ingore certain things like injected HTML to avoid conflicts. It's super tiny/minimal too.</strong></p>
