How can I increase the size of the text on my screen? Also, many of my net pages do not occupy the whole screen; instead they appear as an A4 upright format. How can I change this?
In Internet Explorer and FireFox, go to View -> Text Size to increase the font.
As for the layout of web pages, if they are designed with a "fixed width", they cannot be modified. It's done this way so the layout is the same in any size browser. If your screen is set to a higer resolution than the web page was designed in, you'll always have borders down the sides.
