Facebook comments not responsive

Hi,

I'm facing an issue with Facebook comments box. Since a few uptades (didn't notice it at first) the comments box is not responsive anymore.
I still have the custom lines in my css you guys gave me a few months ago but it doesn't seem to be working anymore.
The container seems to have the 100% width !important attribute when looking with firebug but not the comments(fixed width). I can make it responsive when replacing the fixed width with 100% but can't find how to do it through custom css (doing it in element style with firebug).

Here are the lines you gave me and added to my custom css:

#eblog-wrapper #section-comments .fb_iframe_widget,

#eblog-wrapper #section-comments .fb_iframe_widget span:first-child,

#eblog-wrapper #section-comments .fb_iframe_widget iframe {

	width: 100% !important;

}

Can you help me?

Thanks
