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><b>Client-side scripting</b> generally refers to the class of <a title="Computer program" href="/wiki/Computer_program">computer programs</a> on the <a title="World Wide Web" href="/wiki/World_Wide_Web">web</a> that are <a class="mw-redirect" title="Execution (computers)" href="/wiki/Execution_(computers)">executed</a> <i><a title="Client-side" href="/wiki/Client-side">client-side</a></i>, by the user's <a title="Web browser" href="/wiki/Web_browser">web browser</a>, instead of <i><a title="Server-side" href="/wiki/Server-side">server-side</a></i> (on the <a title="Web server" href="/wiki/Web_server">web server</a>). 
	<br>This type of <a title="Computer programming" href="/wiki/Computer_programming">computer programming</a> is an important part of the <a title="Dynamic HTML" href="/wiki/Dynamic_HTML">Dynamic HTML</a> (DHTML) concept, enabling <a title="Web page" href="/wiki/Web_page">web pages</a> to be <a class="mw-redirect" title="Script (computer programming)" href="/wiki/Script_(computer_programming)">scripted</a>; that is, to have different and changing content depending on user input, environmental conditions (such as the time of day), or other variables.</p>
