I've created and maintain two sites for non profit orgs that I belong to & based on Dreamweaver templates I started with many years ago. As a rank amateur I realize I've created a dog's breakfast of code that is far from "well formed" - so apologies..

The problem - the sites are not mobile friendly and the challenge of redesigning them for phones and tablets is huge and beyond my current knowledge, though I will tackle that eventually (tips on beginners' resources would be welcome) but for now I would be happy if the whole centred image would appear on a small screen as a starting point. Zoom to read is OK for now but the left side bar is missing it's first three and a bit characters and I cannot understand why this is.

Any tips would be MOST welcome!
