So I finally fixed the comment widths, using the following in the style.css:
#edit-comment{
width: 430px;
}
#comments {
width: 430px;
}
#comment-form {
width: 430px;
}
It’s the only thing I’ve been able to fix today. I still can’t make the fckeditor stop centering while also showing the custom styles. It’s very insane making.
