Coca-Cola principles
Coca-Cola is usually bottled in bottles of 2 litres, 1.5 litres, 1 or 0.5 litres and in cans of 0.33 or 0.25. It is obvious that the larger the capacity, the higher the price. And for sure, any person noticed that the price of a bottle grows not in proportion to the volume increase. Or, it would be more correct to say, it falls not in proportion to volume decrease.
You can not buy 1-litre bottle of cola two times cheaper than a 2-litres bottle. The can of 0.33 litres does not cost 3 times less than the 1-litre capacity of the drink. The volume of 0.1 litres does not exist in nature at all, and if such a volume existed, it certainly would not cost 5 times cheaper than a 0.5-litres bottle.
It's all about the package. Coke itself worths a penny compared to the process of manufacturing, transporting and storing plastic bottles and aluminium cans. Bottles of less volume are not as profitable to supply and store as large bottles. On the shelf, which would fit 10 two-litres bottles, do not fit 20 litres or 40 half-litres bottles. However, small capacity is in much higher demand: no one will buy a two-litre bottle when one just wants to drink.
In the web design, package is the concept of design, in HTML it is the basic set of CSS classes, in programming it is the backbone of the future architecture and a set of core functions. These entities are produced by the human brain and are the most expensive building material of the future product. On the contrary, coke represents page content. It is a cheap substance that can be provided almost for free.
For this reason, a website of 10 pages does not cost twice as much as a 20-page website. For this reason, 10 small pages can not cost as much as 5 large pages. Design, the package of the site, should be at first developed, created, produced by the work of the designer. It can not be distributed by weight, scooped out of a bottomless barrel.
The principle of Coca-Cola prescribes to evaluate the package, rather than the volume of the filling.
