I'm using the Atahualpa Theme, and I like the general layout, but I'd like to modify one thing about it: every time an excerpt needs to be displayed (such as when displaying results from a Category or a Tag), I want them to be displayed in 3 columns.
Preferably, I'd like it if the posts were displayed in the following order, from newest to oldest:
1 2 3
4 5 6
7 8 9
Thanks for reading, and any help you can give :)
