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.

Looking for quick-add? Try the external resource search, it's quicker and gives you access to the most recent version of thousands of libraries. ☝️

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

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.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

<p>Unlike other css-stylable checkboxes, this one does not break the element&rsquo;s behavior.</p>
<ul>
  <li>You can tab/shift-tab between the checkboxes (after clicking inside the results window of this demo)</li>
  <li>You get a focus outline, so you know where you are</li>
  <li>The style of the focus outline is the native style of the browser you are using (i.e. blurred blue for Chrome and Safari, dotted black for Firefox)</li>
  <li>While focused, you can check/uncheck using the spacebar</li>
  <li>You can check/uncheck by using the mouse to click on the box itself, or on the box&rsquo;s label</li>
  <li>Browsers which do not support some variation of the appearance property revert to default checkbox styling (so no harm done)</li>
</ul>

/*
 *	The use of the appearance property was suggested by an article by Danny Markov at:
 *		http://tutorialzine.com/2015/07/quick-tip-style-form-elements-with-pseudo-selectors/
 *
 *	The appearance property has never been fully implemented by any browser, and is considered
 *	problematic. However, as of December 2016, there is now some talk of instituting a limited form:
 *		https://drafts.csswg.org/css-ui-4/#appearance-switching
 *
 *	This works on:
 *		Mac
 *			Safari
 *			Chrome
 *			Opera
 *		Windows
 *			IE
 *			Chrome
 *		iOS
 *			Safari
 *			Chrome
 *			Opera
 *			Firefox
 *
 *	IOW, it works in everything except desktop Firefox (not tested on Android).
 *
 *	The strange thing about Firefox is that -moz-appearance does not work the same as -webkit-appearance.
 *	If -moz-appearance is omitted altogether, the default rounded/shaded blue checkbox is used, as expected.
 *	But when -moz-appearance is included, it does have some effect: it styles the box with a 2px gray inset border,
 *	white background,	and its own checkmark character, but it does allow you to specify your own height and width.
 *	In the case of this particular site, I judged that this compromise is still better than the default,
 *	and so kept -moz-appearance in the css.
