[SOLVED] astroidxhtml outline being loaded

Hi
When I apply ?tp=1 to my article and category pages, it returns that the style being used is "astroidxhtml outline" yet this isn't listed anywhere that I can find. 
I want to apply some custom css to shape how the articles and category pages look but I can't find a place to do this. 
Please advise?

Many thanks
Rob

Hi Rob,

Custom CSS is done in the template options at custom code custom css.
