Are there more ways to style the upfront blog layouts?

I am playing with the upfront child theme and am curious if there is a way to style the blog posts layouts on the blog page and the category pages into a grid style or something similar?

The only style I see now is a list view (one after the other down the page.

I see that individual elements of the post can be changed, but that isn't what I want.

Thanks,
Jenn
