These pages are consequently difficult to maintain because they become fragile. Necessary changes to this page may accidentally break another part of the page because of the heavy mixture of presentation and code elements. It is also difficult for more than one developer to work on the pages at the same time. Many large organizations have dedicated user interface designers, whose job is the generation of the presentation layer. When the code and presentation are mixed, it is difficult to separate responsibilities.
