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 URLs 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 its URL and the proper URL extension.

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.

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 esm.sh, which makes packages from npm not only available on a CDN, but prepares them for native JavaScript ESM 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.

        <h1>CSS3 Parallax Cover Section</h1>
        <p>This is a cool vertical parallax scrolling effect that can be created in pure CSS.</p>
        <p>Note that the purpose of this pen is to act as a learning exercise, demonstrating the effects of CSS3 properties such as 3D transforms, SVG backgrounds, viewport units and so on.</p>
        <p>At the moment mobile compatibility with this technique is a little scratchy and it works best in landscape orientation, so it's not ideal for production use.</p>

        <p>The author of these Travels, Mr. Lemuel Gulliver, is my ancient and intimate friend; there is likewise some relation between us on the mother’s side.  About three years ago, Mr. Gulliver growing weary of the concourse of curious people coming to him at his house in Redriff, made a small purchase of land, with a convenient house, near Newark, in Nottinghamshire, his native country; where he now lives retired, yet in good esteem among his neighbours.</p>
        <p>	Although Mr. Gulliver was born in Nottinghamshire, where his father dwelt, yet I have heard him say his family came from Oxfordshire; to confirm which, I have observed in the churchyard at Banbury in that county, several tombs and monuments of the Gullivers.</p>
        <p>	Before he quitted Redriff, he left the custody of the following papers in my hands, with the liberty to dispose of them as I should think fit.  I have carefully perused them three times.  The style is very plain and simple; and the only fault I find is, that the author, after the manner of travellers, is a little too circumstantial.  There is an air of truth apparent through the whole; and indeed the author was so distinguished for his veracity, that it became a sort of proverb among his neighbours at Redriff, when any one affirmed a thing, to say, it was as true as if Mr. Gulliver had spoken it.</p>
