We'd like to customize the look of our SharePoint 2010 pages and sites but didn't know what some best practices are:
- We'd like to change the look of pages some without breaking the link between them and their master pages. In other words, if you change a page in Designer, it won't take the changes from the master page later.
- Also, we'd like to create our own CSS styles and modify existing styles. What's the best way to do this? Should we use our own CSS file?
- Will these changes cause problems if we later need to upgrade to a newer version of SharePoint?
Thank you and sorry if these are newbie questions :)
