how to change font size

Hi bin261,

You've taken a wrong turn on the information highway, and would up in a community where the topic is issues and techniques with Apple's word processing and page layout application, Pages.

To view a web page, you would use a Browser application, such as Safari or Firefox.

Safari has a setting in Safari Preferences where you can set the minimum size text to be shown on web pages you are viewing:

(The image is from an older version of Safari. Yours will likely be different, but the setting should be in the same category.)

You can also expand the content of most web pages with a two finger 'spread' action on the keypad or on a Magic mouse, or by pressing command-plus sign on the keyboard.

To reverse the process, use a two finger pinch, or press command-minus sign.

Pressing option-command-8 will toggle between 'maximum expansion' and 'normal scale'.

The trackpad commands work on Apple applications, and are supported in some, but not all third party applications.

The Keystroke shortcuts are more widely supported in the software I've been using.

Regards,

Barry
