Change Text Size
With almost all modern browsers you can hold down the Ctrl key on your key board (Command key on a Macintosh) and press the + (plus) key to increase the text size or - (minus) key to reduce the text size.
You may also click your browser's View menu -> Text Size or Zoom. Choose the Larger or Smaller font sizes until you can easily read the web page.
