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 is required to process package imports. If you need a different preprocessor remove all packages first.

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.

                <h1>Mobile Safari crash issue</h1>
<p>ORIGINAL PROBLEM: I have a Bootstrap input group with an input on the left and a button on the right, except I want to overlay an arrow on the left of the input, so I wrap the input in a container div, and give it a sibling arrow div (which is used to display a CSS triangle). If you type something into the input and then tap the arrow it causes Mobile Safari to crash.</p>
<p>UPDATE: I have now managed to extract the 2 lines from Bootstrap required to reproduce the issue.</p>
<div class="input-group">
  <div class="my-container">
    <input class="form-control">
    <div class="arrow-container">
       <div class="arrow"></div>



                // prettiness
body {
  margin: 20px;

// bootstrap
.input-group {
  display: table;
.form-control {
  float: left;

// arrow
.arrow-container {
  z-index: 2;
  position: relative;
  width: 40px;
  height: 20px;
.arrow {
  width: 0;
  height: 0;
  border-left: 20px solid transparent;
  border-right: 20px solid transparent;
  border-top: 20px solid #555;
