While surfing on Web, today I visited the website of a graphic and web designer Nigel Buckner who is based in London. He has provided lot of training materials about web design in CSS. These training materials contain simple and excellent examples of CSS code which can be understood by any person having basic knowledge of HTML and CSS. Please have a look at training materials provided by this designer here. It shows that Nigel Buckner is not only a designer but also a good trainer.
