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.

<div class='slanted'>
<p>I was updating my portfolio and wanted to use the forward <span class='no-break'>slash ( / )</span> as a graphic element in the site's main layout. It seemed like it would be easy at first glance, but as I began digging into it actually presented a few very interesting challenges.</p>
<p>I started by looking around for examples of non-rectangular containers that allowed text to flow naturally inside of them. I assumed it'd be possible with CSS since programs like Adobe Illustrator and Microsoft Word have been doing it for years. I found the CSS Shapes Module and that works very well for simple text content. It can even full justify the text. However it doesn’t allow content to scroll within the container so as the user scrolls down, the entire slanted container appears to move left, which wasn’t the effect I wanted. Instead I took a simpler approach and simply added a transform: skew to the container:</p>
<img class="normal" src="https://i.imgur.com/HLw6SuM.png" />
<p class="normal">That was a good start, scrolling worked as expected and resizing was handled with only CSS, but the obvious problem is that now the text and images are slanted as well. I made a few attempts to solve this with CSS but eventually came up with an even simpler solution: create a new font with the reverse slant using FontForge, an open-source font editor.</p>
<p>I'd chosen Roboto Condensed Light for the site's main content so I opened the .ttf file in FontForge, selected all the glyphs, and applied a skew of 14 degrees to compensate for the container’s slant, and saved it out as Roboto-Rev-Italic.ttf.
</p>
<p>That worked great for text, even selecting functioned normally. For images and video, which are display:block elements I was able to simply apply the reverse slant to their transform property. Pseudoelements background give them to span the entire width of the container as well.

<p>See it in action at <a href="https://daveseidman.com" target="_blank">daveseidman.com</a> and use the comments section to suggest other methods, I’m curious to see other way of achieving the same effect. </p>
