How to Change Text Size or Colors
The WAI Web site is designed to let you change the text size, text and
background colors, and other display settings through standard
browser settings.
This page shows you how to use some of these browser display settings.
Most Web browsers include functionality to let you increase or decrease
the text in a Web page. For example, to increase text size:
Browser |
Example |
Menu Items |
Macintosh Shortcut |
Windows Shortcut |
Internet Explorer |
|
View >
Text Size >
Largest |

Firefox,
Netscape |

Why doesn't this work with some
other Web sites?
The browser settings on this page should work when browsers and Web sites
meet WAI guidelines and are designed for
accessibility, flexibility, and user control. However, some browsers do not
provide as much user control, and some Web sites are designed to defeat
browser settings. Text resizing does not work well in browsers and Web sites
that do not meet accessibility guidelines.
- In Internet Explorer Version 6 and earlier, the text may not resize because
the Web site is designed with "hard-coded" or "absolute" text sizes. To
override Web site setting:
- Menu items: Tools > Internet Options
- In Internet Options dialog box: Accessibility button
(bottom right)
- In Accessibility dialog box:
[/] Ignore colors specified on Web pages
[/] Ignore font styles specified on Web pages
[/] Ignore font sizes specified on Web pages
- In Firefox early versions, the text should resize even if the Web
site text is not "coded" for flexibility. However the sections of the Web
site may not resize, making it difficult to use the site with large text.
This is because the Web site was designed with "hard-coded" or "absolute"
sizes. Firefox does not resize images.
- Opera resizes all aspects of a Web site, including
font, images, and sections. Resizing should work fairly well in
Opera, even if the Web site is not "coded" for flexibility.
Turning off the style sheet gives a plain layout view, which:
- makes text black on a white background (or however your browser is
set)
- puts all the information in one column (called "linearized")
- leaves content images
- removes background images

Many browsers provide functionality to set different aspects of font and
color. Below are examples of how to access this functionality.

It is not an accessibility requirement that Web sites include information
on changing text sizes and colors like this page. WAI chose to include this
information to help people who want to know how to change their browser
settings and may not know how.
Web browsers and Web sites should be designed following
WAI guidelines so that people can easily change text
sizes and colors.
W3C WAI does not endorse specific Web browsers and does not recommend one
browser over another. While some common browsers are included in this page,
mention of a specific browser does not imply endorsement or
recommendation.
