[TYPO3] CSS styles only working with tt_content?!

[tapio]

None of the  FORMS
> on my page change, even though I defined styles for them in CSS  Styler. 

it would be a good idea to define classes for different types of form 
elements, for example


tt_content.mailform.20 {
   params.radio = class="radio"
   params.check = class="check"
   params.submit = class="submit"
   params.reset =  class="submit"
}



> Also some EXTENSIONS don't accept CSS changes, like e.g. the  Modern 
> Linklist.

as default plugins set embedded style sheets, which override linked 
style sheets if they are belo the link tag. These style sheets must 
disable, for example


plugin.tt_news._CSS_DEFAULT_STYLE >
plugin.tx_veguestbook_pi1._CSS_DEFAULT_STYLE >

If you disable all of them you can use an external style sheet defining 
all CSS.
