In this project, the task was to create a prototype of a store in which it was possible to select a product and at the same time calculate, as in this example, construction costs. All mechanics were determined by the client. That is, when choosing a material, you will immediately receive information about how many goods are needed for your region with a certain wall thickness.
The template turned out to be very workable and flexible. I repeat, the prototype is presented in this example, because against the background of working capacity the client decided to save on optimization and, therefore, on this site you can see more examples of this work:

As a result, the client decided that the HTML option for this work would be the best and posted everything on his site. If the site does not load these examples, unfortunately, in this matter I was already not strong. Since no one began to allocate funds for revision.
Nevertheless, the idea is very interesting and workable.
