Learning this series of tutorials requires a certain HTML and CSS basis, which means that you have done Web pages before and will use a table layout. If you are just beginning to learn web production, do not know what is the table layout and HTML and CSS, we recommend that you first to recharge, otherwise you will be very difficult to learn this tutorial or do not understand.
Due to the time relationship, this tutorial will only explain some of the basics, allowing you to stride from the original table layout to the Web Standard (DIV+CSS) layout, using Web standards to make common pages, which is also the purpose of this tutorial.
This tutorial more step-by-step in the form of examples to explain what key points or difficulties to explain what, less to explain the concept. Because the concept of these things are difficult to understand, or to understand that you are not necessarily able to understand, understand and not necessarily understand. So leave the concept to everyone to further study.
