How to make Facebook comments widget a fluid width?

Question

Is it possible to make Facebook's comments widget a fluid width? Their documentation shows a width field for the fb:comments xfbml or iframe which is specified as:

• width - the width of the plugin in pixels. Minimum recommended width: 400px.

So maybe it's not possible...

Answer 1

Alan your solution was working however it looks like facebook updated their plugin and broke the style. I got it working again using the universal selector:

.fb-comments, .fb-comments * {     width:100% !important; } 

Answer 2

I found a solution using css. Inspiration came from this article http://css-tricks.com/2708-override-inline-styles-with-css/

.fb-comments, .fb-comments iframe[style] {width: 100% !important;}
