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. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

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.

If the stylesheet 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 CSS 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.

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

If enabled, your code will be formatted when you actively save your Pen. Note: your code becomes un-folded during formatting.

          | Star
    main.article
      p
        | <span class="first-letter">W</span>eb Typography obsessed me. As many others, 
        | I fell in the trap of optimizing legibility. Definitly not an easy task.
        br
        | Among all the contenders for the best reading experience on the Web, a name is 
        | always present and noteworthy: <strong>Medium.com</strong> .
      p
        | Looking for the arcane secrets that regulates good legibility, I immediately realized 
        | that I needed to follow in the footsteps of the masters. So I started dissecting the rules that
        | makes <strong>Medium</strong> typography, well, great.
      p
        | There were long hours of <strong>tremendous effort</strong>, days and days of <strong>prolonged pains</strong>...
      blockquote
        | Now I want to share with you the results of those long hours 🦋
      h2 An unexpected journey
      p
        | <span class="first-letter">C</span>omes out that nothing is better than a big first letter to super-charge your style.
        | Rules are simples. A big letter that spans exactly two rows. Play with <code>line-height</code> to get it right.
      h2 The hero
      p
        | We all know who the leader is.
        br
        | When designing a website you have to take into account fonts for three sectors: the <strong>content</strong>, the <strong>UI</strong>, the <strong>brand</strong>.
        br
        | Specifically I found that the best free alternatives <i>(Google Fonts)</i> to the handcrafted fonts that <strong>Medium</strong> uses are respectively <span class="highlighted">Lora</span>,
        | <span class="highlighted">Montserrat</span> and <span class="highlighted">Playfair Display</span>. 
        br
        | I discovered with delight that the last one mimics almost perfectly the effect created especially for <code>blockquote</code>.
      h2 Content font
      p 
        | The content font should be a serif one, to gently bring your eyes from one letter to the other with
        | the lowest amount of effort.
        br
        | <code>line-height</code> and <code>letter-spacing</code> are vital here. Play with those parameters to make the most out of your
        | font of choice. However at <strong>Medium</strong> you'll find almost an empty line of space in the middle of two lines of text (<code>line-height: 1.58;</code>).
        | While the space between the charachters is kept a little bit on the negative side (<code>letter-spacing: -0.03;</code>) to make words feel more compacts.
      h2 Brand font
      p 
        | The purpose of this font is to enforce the presence of our brand during the navigation experience.
        | We can use it for titles and, here and there, for some minutiae.
      blockquote Blockquotes, for example 🤫
      h2 UI font
      p 
        | The font used for all the UI elements is preferably a sans-serif one. It should create contrast with the content font.
        | Its color could be a little bit lighter than the one used for the main content. 
        br
        | It needs to be readable given the background-color of your page 
        | but not distracting from the main purpose of the page. <span class="highlighted">Reading!</span>
        br
        | You can use it also for <code>h2</code> making the titles for your paragraphs. Here the color should be the same as the one used for the main title.
      h2 <span class="highlighted">The highlight</span>
      p
        | To highlight a word or phrase you can wrap them in a <code>span</code> element and <span class="highlighted">set the background to a color that reminds of your brand color identity</span>.
      h1 Every Title
      p.subtitle `Needs a subtitle`
      p
        | Here we find <code>rgba(0, 0, 0, 0.54)</code> to give meaningful informations without grabbing the attention that the title, main charachter, deserves.
      h2 The length
      p.lineLength 
        | The length of a line of text should never be longer than <code>740px</code>. So our eyes are not forced to run from left to right on the page. 
      h2 The color
      p 
        | The text color should be <code>rgba(0, 0, 0, 0.84)</code> on a <code>rgba(255, 255, 255, 1)</code> background to ensure the best contrast possible.
      h2 Conclusion
      p
        | As always, the strict first rule of design is that there are no strict rules.
        br
        | But, if you are in trouble... 
      blockquote Use Medium.css ✍️
      br
      br
      p Let me know what are your toughts about Web Typography, I am eager to hear from you!
