If the website is displayed in language that uses right-to-left direction of written text (typically arabic languages), the CSS style of the BODY element is set to RTL (<body class="RTL">). You may need to add right-to-left specific CSS styles modifications.
RTL in UI culture vs. content culture
The user interface direction (RTL or LTR) is driven by the preferred UI culture of the current user. The content direction is driven by the preferred (content) culture of the current user.
Original LTR style:
border-right: solid 1px #cccccc;
border-left: solid 1px #cccccc;
Adding culture-specific fonts
If your culture uses specific fonts that are not available in the WYSIWYG editor, you need to configure it:
1. Open file <web project>\CMSAdminControls\FCKeditor\fckconfig.js in notepad.
2. Add your font names on the following line:
FCKConfig.FontNames = 'Arial;Comic Sans MS;Courier New;Tahoma;Times New Roman;Verdana';
3. Save the file.
4. Clear the cache of your web browser (Internet Explorer: Tools -> Internet Options -> General -> Delete files..., check the "delete all off-line content" box and click OK).
5. Close the browser and sign in to Kentico CMS Desk again. Now you should see the new font(s) in the WYSIWYG editor's font list.
