CSS Base

Vendor Prefixing

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.

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.

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.


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.

//Identifier le bouton dans le DOM
var monBouton = document.getElementById("mon-bouton");

//Trois manières alternatives d'associer une fonction à un événement :
//1. Événement click avec association d'une fonction, sans ()!
monBouton.onclick = showFeedbackClick
//2. Événement mouseover avec méthode addEventListener();
monBouton.addEventListener("mouseover", showFeedbackOver);
//3. Événement mouseout avec fonction anonyme
monBouton.onmouseout = function() {
 document.getElementById("feedback").innerHTML += "La souris n'est plus sur le bouton<br>";
