Stef,
It is possible to add your own custom styles to the Styles dropdown but that wouldn't fix the issue at hand. FCKeditor randomly adds extra <p>&#160</p> tags to end of content. You would have to then edit the content and set the style for the extra <p> element to the style you have created that removes the extra space. At this point, you might as well just remove the extra <p> element.

Tim,
Setting the margin and padding to 0px for all <p> elements inside the content areas is not desireable because this would create a lot of issues with content whitespace and confuse users.

-Joe D.

Using the enter key creates a <p>, using shift enter creates a br

In the grand scheme usually its desireable to have some padding or margins on p elements so we wouldn't typically remove it from all p elements.

We just don't want it to affect the layout of the image but the extra p that fckeditor wraps around the img by default is problmatic. Its not needed and it affects the layout of the img. If you remove the p that surrrounds the img using source view and you save without switching back to wysiwyg view its possible to get rid of the p, but then that becomes a user training issue. If we could find a way to fix this behavior in fckeditor it would be better all the way around, but its not an easy thing t figure out how to fix it.

Best,

Joe
