Le Corbusier’s answer to the standardization of the construction industry was his modular. It was developed on the principles of proportions set forth by the “Golden Section” and Fibonacci sequences. However unlike his predecessors, Le Corbusier regulated his proportional schema to the realm of relative rather than absolute standards (34). “Taking man in his environment, instead of [utilizing] universals” Le Corbusier was able to quell some skeptics due to its lack of “metaphysical connotations”(35) Le Corbusier stated in his own manifesto that “man looks at the creation of architecture with his eyes, which are 5 feet 6 inches from the ground (Fig. 13).(36)” Relating the human body to Modulor enabled a “co-ordination at every level from town planning to furniture.”(37) The Modulor which consisted of “two divergent series of irrational numbers derived from the Golden Section” had its roots in the early proportional explorations by Le Corbusier in his work on the purist Villas like that of Graches (Fig. 12)(38).
You will NOT find a solution that you are looking for. Headway is the closest you will get. If you are looking to design sites, then we would recommend investing some time in learning the platform. That will vastly improve the overall quality of your work. I learnt by trial and error (exactly the same thing you are doing). Modifying existing themes to make it work for me. After a little bit of time, I was able to create my own themes. I would highly recommend you to not give up. The founder of genesis and StudioPress learnt the same way.
