I found this article:

I created a child theme using the Twentyten theme as a parent. I am trying to have the WYSIWYG editor use a custom stylesheet.
I added this to my functions.php file:
add_editor_style();
Then I created an editor-style.css file in my child theme's folder and added this:
html .mceContentBody {
max-width:591px;
}
When I go to the WYSIWYG editor and use firebug to check the css that is affecting the .mceContentBody element, I can see that is using my stylesheet, but it is being overrriden by the default editor-style.css sheet from the twentyten theme.
How can I force it to use my editor-style.css file and not the default one?
