I am working in SharePoint Online (Sub-site) and we have 10 pages with custom web parts (for example a Photo library) and custom content (text). Each page consists of 2 'default' web parts with two lists with an XSL template, for now I have added these web parts to one page, and copied that page 10 times in SharePoint Designer, in SharePoint Designer when copying a page the web parts will be copied too. This is not the case if I copy the page online. This is working fine.
Here comes the problem, maintenance costs a lot of time. For example, when the user wants to change the background color of a default web part I have to change it for each page. Another situation is when the user wants to add a default webpart, I have to do this 10 times.
What is the best way to solve this? In SharePoint, is it possible to have a custom template with default web parts and a possibility to add other web parts later by the user?
What's the way to go for this?
