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.

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.

<p>Consideration: <code>.datatitle::after{font:1rem; margin-left:-100%; margin-top:100%; top:1rem; transition: all;}</code><br>
	Can also use: <code>top:2rem;</code>, with another style behavior destabilizing Codepen display of this tooltip. Codepen framing could be the problem.<br> ...Attributes anchor position relative to specific element, herein the typography font app. Codepen api may show weakness here, due to corruption of tool-tip position: unlike on desktop, the large centered SVG icon font tool-tip in codepen is not positioned correctly here, in Safari. <code>.center{transition:inherit;}</code> that sometimes helps style grouped features, no help. Codepen data-title fail on large icon is preceded and followed by correct tool-tip positioning. Class selector <code>.center{font-size:5vmin;}</code> presents no problem. Codepen shows problems when font-size is larger: <code>.center{font-size:85vmin;}</code>. This suggests similar problems in similar environments, elsewhere. FontAwesome, other remote services may also be disrupting Codepen display of code. Most CSS style declarations work well with HTML data-title attribute.

	<li>Works with codepen, with restriction</li>
</ul>
<p>Works in Safari to provide one equal distance between tool-tip and tool-tip anchor for various anchor font sizes. Firefox Tor lags on <code>top:1rem;</code> and removes 2-3 vertical pixels as it eqully adjusts each data-title display's vertical spacing to reflect font-size and line-height for page! Enlarge <code>.center{font-size: 85vmin;}</code>: data-title positioning as expected is restricted by window sizes, including scroll-bars that ignore typographic viewport size in relation to scroll-bar display, for Safari. Method involves viewport adjustments to % and rem measure, in deploying typography apps. Each online font character represents a streamed app.
