<div style="position: fixed; top:0; right:0; width:300px; height: 100%; text-align:justify; overflow:hidden;" class="chat-container">
<iframe id="chat_1" style="width:300px;height:100%;" scrolling="no" frameborder="0" src="http://www.twitch.tv/chat/embed?channel=riotgames&hide_chat=myspace,facebook,twitter&default_chat=jtv"></iframe>
</div>
If you try to adjust the size of the window, you'll notice that the content inside the iframe does not resize accordingly. Unfortunately, I don't have the ability to modify the CSS within the iframe. Is there a workaround for this issue, or am I stuck with the iframe's constraints?
