Using bold, italics and underline at the same time!

Hey everyone,

I have ckeditor installed and working well, I have overridden the default bold/italic/underline tags within config.js using the following code:

   config.coreStyles_bold = { element : 'span', attributes : {'style': 'font-weight: bold'} };
   config.coreStyles_italic = { element : 'span', attributes : {'style': 'font-style: italic'} };
   config.coreStyles_underline = { element : 'span', attributes : {'style': 'text-decoration: underline'}};

This is nearly fine and creates a span tag using the relevant variable making it valid. The only problem is that I can only have one style set at a time, ie if i make a word bold this works fine, but then if i make it underlined it removes the bold setting completely and replaces it with underline. Is there anyway to use these simultaneously without having to use <b> / <strong> / <u> / <i> tags?

Any help you can give would be much appreciated, thanks so much.

Dave
