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.
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.
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.
The resource you are linking to is using the 'http' protocol, which may not work when the browser is using https.
CSS preprocessors help make authoring CSS easier. All of them offer things like variables and mixins to provide convenient abstractions.
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.
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).
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.
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 preprocessors can help make authoring JavaScript easier and more convenient.
Babel includes JSX processing.
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.
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.
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.
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.
If active, Pens will autosave every 30 seconds after being saved once.
If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.
If enabled, your code will be formatted when you actively save your Pen. Note: your code becomes un-folded during formatting.

<h2 class="blog-post-title">Sample blog post</h2>
<p class="blog-post-meta">January 1, 2021 by <a href="#">Mark</a></p>
<p>This blog post shows a few different types of content that’s supported and styled with Bootstrap. Basic typography, lists, tables, images, code, and more are all supported as expected.</p>
<hr>
<p>This is some additional paragraph placeholder content. It has been written to fill the available space and show how a longer snippet of text affects the surrounding content. We'll repeat it often to keep the demonstration flowing, so be on the lookout for this exact same string of text.</p>
<h2>Blockquotes</h2>
<p>This is an example blockquote in action:</p>
<blockquote class="blockquote">
<p>Quoted text goes here.</p>
</blockquote>
<p>This is some additional paragraph placeholder content. It has been written to fill the available space and show how a longer snippet of text affects the surrounding content. We'll repeat it often to keep the demonstration flowing, so be on the lookout for this exact same string of text.</p>
<h3>Example lists</h3>
<p>This is some additional paragraph placeholder content. It's a slightly shorter version of the other highly repetitive body text used throughout. This is an example unordered list:</p>
<ul>
<li>First list item</li>
<li>Second list item with a longer description</li>
<li>Third list item to close it out</li>
</ul>
<p>And this is an ordered list:</p>
<ol>
<li>First list item</li>
<li>Second list item with a longer description</li>
<li>Third list item to close it out</li>
</ol>
<p>And this is a definition list:</p>
<dl>
<dt>HyperText Markup Language (HTML)</dt>
<dd>The language used to describe and define the content of a Web page</dd>
<dt>Cascading Style Sheets (CSS)</dt>
<dd>Used to describe the appearance of Web content</dd>
<dt>JavaScript (JS)</dt>
<dd>The programming language used to build advanced Web sites and applications</dd>
</dl>
<h2>Inline HTML elements</h2>
<p>HTML defines a long list of available inline tags, a complete list of which can be found on the <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element">Mozilla Developer Network</a>.</p>
<ul>
<li><strong>To bold text</strong>, use <code class="language-plaintext highlighter-rouge"><strong></code>.</li>
<li><em>To italicize text</em>, use <code class="language-plaintext highlighter-rouge"><em></code>.</li>
<li>Abbreviations, like <abbr title="HyperText Markup Langage">HTML</abbr> should use <code class="language-plaintext highlighter-rouge"><abbr></code>, with an optional <code class="language-plaintext highlighter-rouge">title</code> attribute for the full phrase.</li>
<li>Citations, like <cite>— Mark Otto</cite>, should use <code class="language-plaintext highlighter-rouge"><cite></code>.</li>
<li><del>Deleted</del> text should use <code class="language-plaintext highlighter-rouge"><del></code> and <ins>inserted</ins> text should use <code class="language-plaintext highlighter-rouge"><ins></code>.</li>
<li>Superscript <sup>text</sup> uses <code class="language-plaintext highlighter-rouge"><sup></code> and subscript <sub>text</sub> uses <code class="language-plaintext highlighter-rouge"><sub></code>.</li>
</ul>
<p>Most of these elements are styled by browsers with few modifications on our part.</p>
<h2>Heading</h2>
<p>This is some additional paragraph placeholder content. It has been written to fill the available space and show how a longer snippet of text affects the surrounding content. We'll repeat it often to keep the demonstration flowing, so be on the lookout for this exact same string of text.</p>
<h3>Sub-heading</h3>
<p>This is some additional paragraph placeholder content. It has been written to fill the available space and show how a longer snippet of text affects the surrounding content. We'll repeat it often to keep the demonstration flowing, so be on the lookout for this exact same string of text.</p>
<pre><code>Example code block</code></pre>

<blockquote>
<p>Longer quote goes here, maybe with some <strong>emphasized text</strong> in the middle of it.</p>
