How to make facebook comment box width 100%?

Question

i am using this code to put a facebook comment box to my page,

Answer 1

With jQuery you can over-write the hard-coded width before it loads the Facebook comment box.

$('document').ready(function(){
    $('.fb-comments').attr('data-width',$('body').width());
});

p.s. you can replace 'body' with any other element you want the comment box to match.
