Hi, all. I'm working on a Website that requires the client to update a specific section (300w x 500h) of the home page. They're basically posting new data every week. I don't want to give them access to the home page file (index.html), as there's a risk that they can mess things up. Is there some sort of simple javascript (or other) code, or CMS that I can add that is isolated, and only lets the client to update that specific isolated rectangle box on the home page?
