I'm not seeing the css styling for Card tabs shown in the docs, so I'd like to tweak the css for that element and perhaps other items as well. When I follow the CSS editing tutorial/instructions, I end up looking at a big, empty text box in which I'm supposed to paste new CSS.
The view does not make sense to me because I'm looking to tweak default elements that are styled with the default CSS. To change the CSS, I'd have to go to the HTML view of a page, look up the element IDs and classes, then go back to the blank CSS textbox and enter new CSS. This seems tedious, so I suspect I'm missing something obvious. Is it possible to view and edit the space CSS directly?
