Be prepared to create alternative pages for browsers that do not support your page design. Different users and browsers may also use different default fonts and font sizes when accessing your carefully designed page. In a framed page it is possible to have the text run out of the frame and be unviewable to some users. Like film and television the web has a screen shape and area. While the default frame gives the web its basic shape, the area can be significantly different on different sized monitors.
Some computer monitors have variable resolution which can affect the size of the browser windows.
