Creating CSS Styles for Use Within JCE 3 Years, 1 Month ago
In the JCE editor, you can select from pre-set CSS styles. These styles are found within your template's master CSS document (template_css.css).
To create new CSS styles which will appear within the styles drop down menu within JCE, all you need to do is add the style to the master CSS style sheet.
However, be sure not to add a "." or "#" in front of the style's name (otherwise it will not show up within JCE).
