How to make the new facebook post embed feature responsive?

I couldn't find any solutions on google which can make the newly introduced facebook posts embed to responsive. Does anyone got a solution or tricks? Thanks

<div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "http://connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script>
<div class="fb-post" data-href="https://www.facebook.com/notes/facebook-security/national-cyber-security-awareness-month/10151630123500766" ><div class="fb-xfbml-parse-ignore"><a href="https://www.facebook.com/notes/facebook-security/national-cyber-security-awareness-month/10151630123500766">Post</a> by <a href="https://www.facebook.com/security">Facebook Security</a>.</div></div>

Answer

If you mean "responsive" as in "responsive design", you can't. Facebook uses a cross-domain iframe for JS/CSS isolation and session security, and it generates the iframe dimensions dynamically based on contents using privileged cross-domain communication, so you can't just play around with CSS to get things how you want them. See this section on official page for the social plugin:

Can I customize how the post is displayed on my web page?

Currently, you cannot customize how Embedded Posts are displayed on your page. The size of the post is fixed to the same dimensions as it's shown on Facebook.

If you mean that the plugin is not displaying properly, you should follow the instructions with the Get Code button on the official page for the social plugin.

Details:

Your markup is missing an app ID. Where did you find this markup? You need to specify an app ID. If you load the JS SDK manually, that means adding it to the parameters of FB.init as seen here. In your case, you are using the shortened URL-based init, where the SDK URL has parameters in its fragment: #xfbml=1 in your example. You will need to change it so it is more like #xfbml=1&appId=1234567890.

Update: You should use the console in your browser's built-in developer tools (or Firebug, etc.) to see info about errors with the JS SDK. When I tried your code on an https:// site, I got this error:

[blocked] The page at https:// ran insecure content from http://connect.facebook.net/en_US/all.js.

so I changed the URL from http://connect.facebook.net/... to a protocol-relative URL: //connect.facebook.net/...

Another option would have been to just try on an http:// site only. At that point, I got the following errors:

Invalid App Id: Must be a number or numeric string representing the application id.
FB.getLoginStatus() called before calling FB.init().

This confirms my suspicion -- you need an app ID. I added an app ID and it works.
