Add External CSS

These stylesheets will be added in this order and before the code you write in the CSS editor. You can also add another Pen here, and it will pull the CSS from it. Try typing "font" or "ribbon" below.

Add External JavaScript

These scripts will run in this order and before the code in the JavaScript editor. You can also link to another Pen here, and it will run the JavaScript from it. Also try typing the name of any popular library.

Save Automatically?

If active, Pens will autosave every 30 seconds after being saved once.

Want a Run Button?

If active, the preview will update automatically when you change code.



<input id="field" autofocus>
<p>When a website like Google auto-focuses the cursor into a text field, this basically <a href="http://www.sitepoint.com/dont-hijack-my-browser/">hijacks</a> the browser's back button functionality. This script fixes this problem.</p>
  <p>You can try a <a href="http://www.impressivewebs.com/google.com.html">raw version at this location</a>, but be sure to view another website first so you'll have something to go "back" to.</p>
  <p>Bonus: I've also added shift-backspace recognition, to have the ability to go forward, too.</p>


              body {
  text-align: center;  

h1 {
  font-size: 50px;
  margin: 20px 0;

input {
  padding: 5px;
  width: 400px;
  margin-bottom: 20px;

p {
  width: 30%;
  margin: 20px auto;
  text-align: left;


              var input = document.getElementById('field'),

input.onkeydown = function(e) {

  if (!input.value) {

    key = e.keyCode || e.charCode;

    if (!(input.isDirty=="true") && (key === 8 || key === 46)) {

      if (!e.shiftKey) {
      } else {

    } else {

Asset uploading is a PRO feature.
