A single screen design maximum desktop width and no more than 6 horizontal sections. Generally this package covers most design requirements for typical landing pages, contact pages, and even more complex tasks such as checkout page design. Bear in mind that you will need multiple screens for certain feature sets that may appear initially to be a single page. An example of this would be a quiz page, where typically there is a start screen, answer screen and finally review screen. That is 3 distinct screens each with their own elements, even if the overall template is fairly consistent from one screen to another.
