I've been playing around with making a custom code for a line width of 60% of the page but can't get it working. Does anyone know what the HTML replacement field should be? I think that's the only problem I'm having.
@LuvMeSumZen, I'd love to know how you got this to work. I have added the custom bbcode (as seen below) and does appear to be recognized... but I just get blank spaces where the line should appear. Any help on getting this to work would be greatly appreciated.
