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

    東京は、日本における政治・経済・文化の中心である。政治面では、日本国政府が本拠地とする。立法府である国会議事堂、司法府の頂点である最高裁判所、行政府の長である内閣総理大臣の官邸、中央省庁街（「霞が関」）などは、いずれも東京の中心部である東京23区にある。経済面では、日本の株式上場企業の本社のほとんどが東京に集中し、近年では（東京圏では）購買力平価（PPP）を基にしても東京都市圏のGDPは1兆5369億ドル（2014年）であり、世界的な経済都市であり、大消費地でもある。文化面では、たとえば現在では（東京都内に）千数百におよぶ劇場・ホール・ライブハウス類があり多数のアーティストたちが活動する場であり、ポップカルチャーなどの新しい文化の発信地でもあり、ミシュランガイドの星つきの飲食店の数は世界最多で、世界各国の食文化が華開いている場所でもある。東京は、日本各地、近隣の国々、世界各国から人々が観光に訪れる都市であり、さらに東京に移住した外国人の人口は2020年1月時点でおよそ57万7千人で、独り暮らしや家族単位の暮らしをしている人々も多いが移民街も形成されており、《多文化共生》、つまり様々な国の文化背景を持つ人々が仲良く暮らすことが、以前からそれぞれの地区の善意の人々によって進められており、近年では行政によっても積極的に推進されている場所でもある。東京のこれまでの道程は決して平坦であったわけではなく、関東大震災や東京大空襲で焼け野原となってしまったこともあるのだが、戦後に復興のために膨大な努力をしたおかげで、現在では世界最大級のメトロポリス・世界都市となっている。東京は明治期にも課題が山積みの都市であったが、現在も、高い犯罪率、人口過密、通勤ラッシュなど、さまざまな課題を抱えている都市である。
