Double flying wing layout

##The Holy Grail layout and the double flying wing layout solve the same problem, that is A three-column layout with fixed width on both sides and adaptive middle column. The middle column should be placed in front of the document flow for priority rendering.

 and margin-right Leave space for the left and right columns. 
The double flying wing layout has one more p tag and 4 less css attributes. Less padding-left and padding-right are used. The left and right p's use relative layout position: relative and the corresponding right and left, and margin-left and margin-right are used more.
