What is Community Theming in Salesforce?

[Nitesh]

Hi Ram
First you need to know what is Theming?
Theming brings about a transformation in the look and feel of a Salesforce Community. It helps to bring a much deeper level of customization. In fact, theming may offer a hierarchical problem, as it becomes complex by using dynamic components,  components written by other users for the App Exchange — as well as page level variations.
