Many sites offer the ability for users to change the color and style of the site to fit their preference. SharePoint has this feature to some extend through themes but changing themes is not a very simple process and requires browsing to several pages.
- Users need to be able to switch themes and have the setting saved
- No page refresh
- Should be able to use both out of the box themes and custom themes
So first I needed to get the CSS files and images for the themes I wanted to use. When you assign a theme to a site all the files for the theme are copied to a folder named _themes in the root of the site.
So what I did was assign each theme I wanted to use to the site one at a time. With SharePoint designer I copied the files folders for each theme into a document library called Site Styles. Each folder contains all the resources needed or the theme to work.
