Hi HighConcept,
There is not a base directory.
For example,
1. I have the page below at the root of my test site.
<?php include_once("cuteeditor_files/include_CuteEditor.php") ; ?>
<html>
<head>
<title>Edit Static Html Example -- PHP Content Management, PHP WYSIWYG, PHP HTML Editor, PHP Text Editor</title>
</head>
<body>
<form name="theForm" action="Edithtml.php?postback=true" method="post">
<?php
$editor=new CuteEditor();
$editor->ID="Editor1";
$editor->EditorWysiwygModeCss="ken.css";
$editor->Draw();
$editor=null;
?>
</form>
</body>
</html>
2. I have the css file below at the root of my test site name "ken.css"
3.Than I add the content below in to editor html view, it show the red style for me in the editor.
<div class="redText">this is a test</div>
Please follow the steps above to test it.
Regards,
Ken
