I have found several posts on how to get your own styles in the dotnetnuke texteditor. I managed to get my styles into the editor, but how can I avoid all the other styles in the dropdown? I can remove default.css in the default portal but then my layout of the admin panel is messed up cause this stylesheet is used by the admin panel.

I also have another question. I can make a list of unordered items and want to apply my own style onto it. So first I make a list of items and then apply my ul style on it. The css is not applied cause dotnetnuke applies my ul class to a span class like this:

<ul>
    <li><span class="orange">blaaaa​</span></li>
</ul>

And it must be this:

<ul class="orange">
    <li>blaaaaa</li>
</ul>

How can I put the ul class on the ul tag automatically? Or do I have to change this in the HTML view every time? Not the behavior that I want cause now I'm doing the html input, but in the future somebody that doesn't know HTML has to input content.
