Message Area Width

[Kiint]

I'm not quite sure how that would apply when I'm using just $messageares within my template?

I've found your post on the subject regarding the Quick Reply editor which does go full width, but without all the editing options which I want to keep.
Do you know how to make this work on the full editor?

discovered that I can alter the message width by using the following:

$stylevar['messagewidth'] = '750px';

which is fine if I want a fixed width, but have tried various methods with % but nothing seems to work...

$stylevar['messagewidth'] = '100%'; //doesn't do anything
$stylevar['messagewidth'] = 100%; //brings up error
$stylevar['messagewidth'] = 'auto'; //doesn't do anything
$stylevar['messagewidth'] = auto; //doesn't do anything

Surely there must be a way?
