Show blocks border in ckeditor
The client's site has a blue background in the cms areas so I've applied the same blue background in the content.css file to try to create a WYSIWYG ckeditor editing window. This works fine until you click the "show blocks" icon in the toolbar which adds the block borders.
The borders are almost invisible agaisnt the blue background because they are dotted and I've been trying to find the style where I can change this to a darker colour and/or solid border but no success so far.
Do you know which style contols this border?
