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.

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 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.

Behavior

Auto Save

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 A thin paint will stick to a thick paint. The shadows are just like the highlights, but we're going in the opposite direction. When you do it your way you can go anywhere you choose.

      p You have to make almighty decisions when you're the creator. When you buy that first tube of paint it gives you an artist license. There we go. The little tiny Tim easels will let you down. Let's just drop a little Evergreen right here.

      p Trees grow in all kinds of ways. They're not all perfectly straight. Not every limb is perfect. I really believe that if you practice enough you could paint the 'Mona Lisa' with a two-inch brush. Just pretend you are a whisper floating across a mountain. This is your world, whatever makes you happy you can put in it. Go crazy.

      p The first step to doing anything is to believe you can do it. See it finished in your mind before you ever start. We'll play with clouds today. Every single thing in the world has its own personality - and it is up to you to make friends with the little rascals. Don't kill all your dark areas - you need them to show the light. We don't want to set these clouds on fire. Every day I learn.
      
      blockquote When you do it your way you can go anywhere you choose.

      p Let's get wild today. Once you learn the technique, ohhh! Turn you loose on the world; you become a tiger. This is probably the greatest thing to happen in my life - to be able to share this with you.

      p I'm a water fanatic. I love water. This is gonna be a happy little seascape. Put light against light - you have nothing. Put dark against dark - you have nothing. It's the contrast of light and dark that each give the other one meaning. Let's put a touch more of the magic here. I'm going to mix up a little color. We’ll use Van Dyke Brown, Permanent Red, and a little bit of Prussian Blue.
      
      p And that's when it becomes fun - you don't have to spend your time thinking about what's happening - you just let it happen. Let all these things just sort of happen. Don't fight it, use what happens. Let's put some happy little bushes on the other side now.
      
      blockquote Don't fight it, use what happens.

      p If we're going to have animals around we all have to be concerned about them and take care of them. I'll go over the colors one more time that we use: Titanium white, Thalo green, Prussian blue, Van Dyke brown, Alizarin crimson, Sap green, Cad yellow, and Permanent red. Anytime you learn something your time and energy are not wasted. This is your world. We want to use a lot pressure while using no pressure at all. Just let go - and fall like a little waterfall.

      p Let's build some happy little clouds up here. Everyone is going to see things differently - and that's the way it should be. Let's do that again. A tree needs to be your friend if you're going to paint him. That's why I paint - because I can create the kind of world I want - and I can make this world as happy as I want it.
