Question

I have these codes on my site

<ul class="tabs">
<li>
<input type="radio" checked name="tabs" id="tab1">
<label for="tab1">Twitter</label>
<div id="tab-content1" class="tab-content animated fadeIn">
<a class="twitter-timeline" href="https://twitter.com/1THUGRadio" data-widget-id="521855935606583296">Tweets by #1THUGRadio</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
</div>
</li>
<li>
<input type="radio" name="tabs" id="tab2">
<label for="tab2">Facebook</label>
<div id="tab-content2" class="tab-content animated fadeIn">
<iframe src="http://www.facebook.com/plugins/likebox.php?href=http%3A%2F%2Fwww.facebook.com%2Fthugcommunity&width=650&colorscheme=light&show_faces=true&border_color&stream=true&header=true&height=500" frameborder="0" scrolling="yes" style="background: white; border: currentColor; border-image: none; width: 650px; height: 500px; overflow: visible; float: left;" allowtransparency="true">

}
animation-duration: 0.5s;
}
When I put the coding in jfiddle.net everything shows up like it should. But when I drop it in the website only the tabs show up, not the content

Answer 1

First off, thanks for the lack of help I got from everyone. So I figured out it needed to have overflow: visible; not hidden.
