Changing Summary Block Font Weight and Size 7.1

Hi,

I'm working on a client site to make the switch from 7.0 (Rally template) to 7.1 (Stanton template). They love the blog layout but don't particularly care for how the blog linking is done (doesn't show "Posted in [category]). I believe I can get around this issue using the summary block so that they can have their home page and still have the site focus on the content, however I realized there are no tweaks for the summary block as I don't use it much. Does anyone know of any code I could use. I've included a screenshot of what we're trying to achieve but with a summary block as opposed to using the actual blog page since when you click a folder, it no longer automatically goes to the first linked in the folder.

Thanks for any help!

You mean change Summary Block layout to your screenshot?

I think this should be possible, if you share link to page where you use Summary, we can check easier
