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.

Insecure Resource

The resource you are linking to is using the 'http' protocol, which may not work when the browser is using https.

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.

          <h2>Here are milestones of Brendan Eich's career:</h2>
            <h3>Early life</h3>
              <ul>
                <li>Brendan Eich grew up in Palo Alto.</li>
                <li>He attended Ellwood P. Cubberley High School, graduating in the class of 1979.</li>
                <li>Eich received his bachelor's degree in mathematics and computer science at Santa Clara University.</li>
                <li>He received his master's degree in 1985 from the University of Illinois at Urbana-Champaign.</li>
              </ul>
            <h3>Netscape and JavaScript</h3>
              <ul>
                <li>He started work at Netscape Communications Corporation in April 1995.</li>
                <li>He completed the first version of a programming language in ten days in order to accommodate the Navigator 2.0 Beta release schedule.</li>
                <li>The language was called Mocha, but renamed LiveScript in September 1995 and later JavaScript in the same month.</li>
              </ul>
            <h3>Mozilla</h3>
              <ul>
                <li>In early 1998, Eich co-founded the Mozilla project with Mitchell Baker, creating the website mozilla.org that was meant to manage open-source contributions to the Netscape source code. He served as Mozilla's chief architect.</li>
                <li>AOL bought Netscape in 1999. After AOL shut down the Netscape browser unit in July 2003, Eich helped spin out the Mozilla Foundation.</li>
                <li>In August 2005, Eich became CTO of the newly founded Mozilla Corporation, meant to be the Mozilla Foundation's for-profit arm.</li>
                <li>Eich continued to "own" the Mozilla SpiderMonkey module, its JavaScript engine, until he passed on the ownership of it in 2011.</li>
                <li>On March 24, 2014, Eich was promoted to CEO of Mozilla Corporation.</li>
                <li>On April 3, 2014, Eich stepped down as CEO and resigned from working at Mozilla.</li>
              </ul>
            <h3>Brave Software</h3>
              <ul>
                <li>Eich is the CEO of Brave Software, an Internet security company which has raised $2.5 million in early funding from angel investors.</li>
                <li>The company's co-founder is Brian Bondy, who worked on Firefox and Khan Academy. The company's employees include Marshall Rose, a network protocol engineer, and Yan Zhu, who worked on SecureDrop and Tor.</li>
                <li>On January 20, 2016, the company released developer versions of its open-source Brave web browser, which blocked ads and trackers and included a micropayments system to offer users a choice between viewing selected ads or paying websites not to display them. A recent update added inbuilt integration of 1Password and LastPass password managers.</li>
              </ul>
            <h3>Basic Attention Token</h3>
              <ul>
                <li>Eich is also the founder of Basic Attention Token (BAT), a "utility token based on the Ethereum technology that can also be used as a unit of account between advertisers, publishers, and users in a new, blockchain-based digital advertising and services platform".</li>
                <li>BAT launched its ICO on May 31, 2017 raising $35 million in just 30 seconds.</li>
              </ul>

              <li>Always bet on JavaScript.</li>
              <li>If the web can be evolved to include the missing APIs and have better performance, [developers] won't need to go
                beyond the web.</li>
              <li>JS had to "look like Java" only less so, be Java’s dumb kid brother or boy-hostage sidekick. Plus, I had to be done
                in ten days or something worse than JS would have happened.</li>
              <li>We're adding a lot of fun features.</li>
              <li>It's been over ten years, hard to believe. It was the Rodney Dangerfield of languages.</li>
              <li>It's time to get back to innovating in the browser space.</li>
              <li>Why the long freeze in JavaScript development? A lot of it had to do with the long freeze on browsers due to the
                IE [Internet Explorer] takeover.</li>
              <li>We're going to learn from Python. JavaScript is pretty close to Python.</li>
