1. Three-column layout, with adaptive middle width and fixed width on both sides;
2. The middle column should be displayed and rendered first in the browser;
3. Allow any column to have the highest height;
4. Only one additional DIV is required Tag;
5. It is required to use the simplest CSS and the least HACK statement;

1. Holy Grail Layout:
