Altering the textarea of the main post box

[Posie]

My forum is wrapped in Joomla therefore the forum width is approximately 774 pixels.  What I would like to do is change the size of the main post box to reflect the fixed width.

Code Select Expand

/* The main post box - this makes it as wide as possible. */
.editor {width: 96%;}

I have tried changing this value however it never changes the width of the box if I am quoting a long url.  My site is a sims fansite therefore members will post links to the official site.  An example is as follows:

http://bbs.thesims2.ea.com/community/bbs/messages.php?threadID=7cc41590e9e3bfad51e5336781829f85&directoryID=2&startRow=1&openItemID=item.2,item.43,item.61,item.41,item.23

The url wraps to some extent in that it is split into the following:

http://bbs.thesims2.ea.com/community/bbs/messages.php?
threadID=7cc41590e9e3bfad51e5336781829f85&directoryID=2&startRow=1&openItemID=item.2,item.43,item.61,item.41,ite
m.23

Does anyone know how I can decrease the width of the textarea?

Code Select Expand

.editor {width: 625px;}

This actually seems to work even though changing the percentage was always ignored
