Have you ever wanted to know how to fix the "problem" with the Joomla editor if your website has a dark background color.

The Problem
In Joomla the standard content editor TinyMCE uses the body tag from your template_css file to display the background in the content editor of Joomla when adding or editing a content item, this means if your website has a dark background, such as JJ Supremacy or JJ Nitro, when adding content, you will not be able to see what you are typing, particularly if the content area is light with dark text, as it means the you will have dark text on a dark background.
