I feel like a huge idiot, because I think I have had to ask this question two times before with other blogs.... but, I am helping a friend set up a simple website for her personal chef business (kitchendiva.wordpress.com). I did this before for her daughter when I had a lot of free time to learn about CSS, most of which I have now forgotten (and these days I'm a law student).
We purchased the CSS upgrade for that blog, and I thought with the other site that to get going editing the basics of the original theme, I had to copy the contents of the style sheet (she wants to use the Fleur de Lys one) into the box and then check "start from scratch and use this." However, when I do that, the page loses all the shaded sections and generally looks crazy, before I even do any editing.
Then I tried copying the entire CSS style sheet code content into that box and checking the first box - still messed up in the same way. Shouldn't I be able to copy the entire stylesheet into the box before making any changes and have the theme look like it's supposed to? Does this make sense and can anyone help me?
