How do I customize the layout of a blog?

[Jeff Johnston]

I would like to change the layout of our company blog, to add things such as a navigation menu bar along the top, topic categories along the side, etc.  Everything I've found online for support so far is either to customize a Confluence Wiki (not what I'm looking to do, I know that just fine) or requires additional programs/coding to interact with the XHTML files directly.

Is there a more user-friendly way to update/change the design layout of a blog?

Afaik Redefined Wiki Original Theme Add-on offers the option to configure Space Blogs instead of the complete Confluence instance.

Anne, Thank you, but I was looking for a non-third party option ideally, but at a minimum a no-cost option (particularly one costing five times Confluence itself).
