CKEditor custom styles from file not showing - ckeditor

Question

I can't seem to add my own CSS file to the CKEditor. I'm downloading a custom version 4.5.8 and include the "StyleSheet Parser" plugin. The "Styles" list has the default styles, but not the ones from my css file.
This the code:
CKEDITOR.config.contentsCss = '../../../css/test.css';
CKEDITOR.replace('editor1');
The editor is loaded successfully, but the "Styles" list does not contain my styles. The location of my css files seems right, when I try other paths I get an error.
This is my test.css:
.testStyle {
color: red;
font-family: "Arial Black", arial-black;
}
Already tried clearing my browsers cache. I tried it in multiple browsers.
I tried one other thing: download the StyleSheet Parser separately, put it in the plugins folder, and use the following code:
CKEDITOR.config.extraPlugins = 'stylesheetparser';
CKEDITOR.config.contentsCss = '../../../css/test.css';
CKEDITOR.replace('editor1');
The "Styles" list is still not showing my style, but when I edit the source code and put my style in like this, the style is applied to the text in the editor(!):
<p class="testStyle">Test text</p>
Sources:
- CKEditor docs for the StyleSheet Parser
- The "contentsCss" option docs

Answer 1

The Styles in CKEditor require an element, so the StyleSheetParser only recognizes rules that include an element and a class name.
You should change your CSS to
p.testStyle {
color: red;
font-family: "Arial Black", arial-black;
}
