Kooboo uses very standard CSS for Theme. You can define a Theme by creating a folder under Binary resource > Theme and then put all .css files in the folder. CSS files can include an image sub folder.
In above example, our default Theme contains one css file and an image folder with all image used by the css.
Using Theme is very simple, right click on any application, open the property window and select the right theme to use.
Kooboo will automatically add reference to all .css files in that theme folder in the order of file name. If a module contains its own .css files. It is recommended to move css files into theme folder.
Important Note: In order to use the theme feature of ASP.NET, Layout template needs to contain a <header runat=”server” /> tag.
