CoreMedia Site Manager Developer Manual, Version 7.5.45-10
3.6. Configuration Using coremedia-richtext-1.0.css | 3.6.1. Supported CSS Attributes

As opposed to the usual browsers the CSS support in Java/Swing is limited and does not cover the complete CSS attributes. Therefore, Java/Swing will display some CSS attributes flawed or not at all. See the Javadoc of the javax.swing.text.html.CSS class of your used JVM for the supported CSS attributes.

Because of these limitations you should always use the preview function of the Site Manager for a check of the used CSS styles.

	Note
	Don't merge the attributes in the coremedia-richtext-1.0.css file. For example don't write "border: solid 1px red" but "border-style:solid; border-width: 1px; border-color: red;". If you edit coremedia-richtext-1.0.css with tools like Microsoft Frontpage, take care that the attributes are not merged on saving.
