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.

+ add another resource

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 feature can only be used by logged in users.

		p Amur leopards are relatively easy to distinguish from other leopard subscpecies because, in order to survive the long cold winter, they have a soft coat with long and thick hair. This gives them a fluffy and extremely aesthetically pleasing appearance - just look at them!
		p Their beauty has been both a curse and a blessing.
		p Their gorgeous coats have made them poached to such an extent that, ten years ago, only about 20 of them were still to be found in the wild.
		p At the same time, their charisma has made them popular in zoos or as vanity "pets" for rich people and had raised the interest in saving them from extinction.
		p For the past ten years however, their numbers have climbed slowly. There are about 50- 60 cats living in the wild today.
