HTML

About HTML Preprocessors

HTML preprocessors can make writing HTML more powerful or convenient. For instance, Markdown is designed to be easier to write and read for text documents and you could write a loop in Pug.

Adding Classes

In CodePen, whatever you write in the HTML editor is what goes within the <body> tags in a basic HTML5 template. So you don't have access to higher-up elements like the <html> tag. If you want to add classes there that can affect the whole document, this is the place to do it.

About the <head>

In CodePen, whatever you write in the HTML editor is what goes within the <body> tags in a basic HTML5 template. If you need things in the <head> of the document, put that code here.

CSS

About CSS Preprocessors

CSS preprocessors help make authoring CSS easier. All of them offer things like variables and mixins to provide convenient abstractions.

CSS Base

About CSS Base

It's a common practice to apply CSS to a page that styles elements such that they are consistent across all browsers. We offer two of the most popular choices: normalize.css and a reset. Or, choose Neither and nothing will be applied.

Vendor Prefixing

About Vendor Prefixing

To get the best cross-browser support, it is a common practice to apply vendor prefixes to CSS properties and values that require them to work. For instance -webkit- or -moz-.

We offer two popular choices: Autoprefixer (which processes your CSS server-side) and -prefix-free (which applies prefixes via a script, client-side).

Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. You can use the CSS from another Pen by using it's URL and the proper URL extention.

Powered by Algolia
About External Resources

You can apply CSS to your Pen from any stylesheet on the web. Just put a URL to it here and we'll apply it, in the order you have them, before the CSS in the Pen itself.

You can also link to another Pen here (use the .css URL Extension) and we'll pull the CSS from that Pen and include it. If it's using a matching preprocessor, use the appropriate URL Extension and we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

JavaScript

About JavaScript Preprocessors

JavaScript preprocessors can help make authoring JavaScript easier and more convenient.

Learn more · Versions

Babel includes JSX processing.

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.

Powered by Algolia
About External Resources

You can apply a script from anywhere on the web to your Pen. Just put a URL to it here and we'll add it, in the order you have them, before the JavaScript in the Pen itself.

If the script you link to has the file extension of a preprocessor, we'll attempt to process it before applying.

You can also link to another Pen here, and we'll pull the JavaScript from that Pen and include it. If it's using a matching preprocessor, we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

Packages

Add Packages

Search for and use JavaScript packages from npm here. By selecting a package, an import statement will be added to the top of the JavaScript editor for this package.

Powered by Algolia
About Packages

Using packages here is powered by Skypack, which makes packages from npm not only available on a CDN, but prepares them for native JavaScript ES6 import usage.

All packages are different, so refer to their docs for how they work.

If you're using React / ReactDOM, make sure to turn on Babel for the JSX processing.

Behavior

Save Automatically?

If active, Pens will autosave every 30 seconds after being saved once.

Auto-Updating Preview

If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.

Format on Save

If enabled, your code will be formatted when you actively save your Pen. Note: your code becomes un-folded during formatting.

	<p>"If I only could, I'd be running up that hill.
If I only could, I'd be running up that hill."</p>
	<p>It doesn't hurt me.
Do you want to feel how it feels?
Do you want to know that it doesn't hurt me?
Do you want to hear about the deal that I'm making?
You, it's you and me.</p>
	<p>And if I only could,
I'd make a deal with God,
And I'd get him to swap our places,
Be running up that road,
Be running up that hill,
Be running up that building.
If I only could, oh...</p>
	<p>You don't want to hurt me,
But see how deep the bullet lies.
Unaware I'm tearing you asunder.
Ooh, there is thunder in our hearts.</p>
	<p>Is there so much hate for the ones we love?
Tell me, we both matter, don't we?
You, it's you and me.
It's you and me won't be unhappy.</p>
	<p>And if I only could,
I'd make a deal with God,
And I'd get him to swap our places,
Be running up that road,
Be running up that hill,
Be running up that building,
Say, if I only could, oh...</p>
	<p>You,
It's you and me,
It's you and me won't be unhappy.</p>
	<p>"C'mon, baby, c'mon darling,
Let me steal this moment from you now.
C'mon, angel, c'mon, c'mon, darling,
Let's exchange the experience, oh..."</p>
	<p>And if I only could,
I'd make a deal with God,
And I'd get him to swap our places,
Be running up that road,
Be running up that hill,
With no problems.</p>
	<p>And if I only could,
I'd make a deal with God,
And I'd get him to swap our places,
Be running up that road,
Be running up that hill,
With no problems.</p>
	<p>And if I only could,
I'd make a deal with God,
And I'd get him to swap our places,
Be running up that road,
Be running up that hill,
With no problems.</p>

Be running up that hill
With no problems...</p>

If I only could, I'd be running up that hill."</p>
