Yes this has been applied. After your note, I added the 2 entries to the main site style sheet and changed all the settings in Irite to correspond as I know this CSS is being picked up and works, but still no joy. The style box shows the two items I have selected in IRite (under :Edit>Styles[Tab]>available styles) but does not seem to want to apply them to the text in the text box on the web site. Other menu items like bold and italic work ok.
The source code shows the correct entry ie class=”standard” in the text field and when you submit the entry the correct style is then displayed, but during editing the changes don’t appear to be dynamic as with the bold or italic buttons etc.
