i noticed, that the dynamic part of a page is the minor part, that matters. the static part, with css, js and so on, needs a lot of attention, while coding. so i tryed some 3rd party stuff, with jquery for success. with“bootstrap“ the div-container are prepared, configured and accesible from the dom-tree and the context in general. the page can be separated with ease and little effort, on version changes. some diagram might help to prepare the page design over all elements.
