Below are instructions on how to change font sizes for three popular internet browsers. If you need to change the font viewing size, please follow these instructions.
1.Firstly you'll need to tell Internet Explorer that you want it to ignore fonts defined by a website. To do this, go to Tools, Internet Options and then select the General tab, and then the Accessibility button.
1.For a Mac, go to Preferences > Content (Tools > Options > Content in Windows).
Although there is an option to set default fonts in Safari, there seems to be only one option to override site-defined styles, which is that you can set a minimum font size. For instructions, see the Safari section under Changing only font sizes. To change font styles, your best bet is to define a user style sheet (see Changing site styles).
