Q:

Changing Look & Fell of Liferay Portal Project

I want to ask for changing look and feel for my portal project. For example main page...
I have html, css, and javascript. I read many documents about hooks project from Liferay site(and also pdf docs), but I could't reach any solution. 
I don't want to change any portlet, I want to change interface of my portal sites.
Could you please help me.

A:

You can change the overrall look and feel of the project using Themes. Themes are like skin which you can apply across a set of pages or just a single page. Check the following link to create the theme
