If you are using Internet Explorer 8 and find a webpage hard to read, because the text appears too small, you can "zoom in" on the webpage, i.e., enlarge the font size, by hitting the Ctrl and "+" (plus) keys simultaneously. You can zoom out, i.e., reduce the font size, by hitting the Ctrl and "-" keys simultaneously.
A webpage designer can choose to specify fonts and their size for a webpage or can rely on the user's browser to pick what is best for the user based on the browser's default settings. So some pages may be harder to read than others, if the webpage designer selected a font that is smaller than the default size.
You can do the same thing on a Mac system with Safari using the command and "+" key to zoom in or the command and "-" key to zoom out.
