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.

Looking for quick-add? Try the external resource search, it's quicker and gives you access to the most recent version of thousands of libraries. ☝️

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

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.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

    This examples shows how to use geo.admin.ch WMTS tiles in the new LV95 frame (<a href="https://epsg.io/2056" target="_blank">EPSG:2056</a>).<br>
    <p>The WMTS tiles are reframed <em>on-the-fly</em> using <a href="http://mapproxy.org">MapProxy</a> and the NTv2 <a href="https://www.swisstopo.admin.ch/internet/swisstopo/en/home/topics/survey/lv95/lv03-lv95/chenyx06.html"> CHENyx06 triangular transformation network </a>. Hence the accuracy is well beyond the resolution of the displayed layers. Without this you would see in region like the south Ticino and the Poschiavo area, a shift up to 1.5 meters between the old and the new frame. See <a href="//map.geo.admin.ch/?layers=ch.swisstopo.koordinatenaenderung&layers_opacity=0.75&lang=en" target="_blank">LV95 Coordinate changes</a> for some background informations.</p>
