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?
