b. Keep backgrounds simple. Make sure
there is enough contrast. Even people with 20/20 vision can have
difficulty reading information at sites with busy backgrounds, sometimes called
wallpapers. Many backgrounds obscure text and make reading more difficult. This
is especially true for people with low vision or colorblindness as well as for
people using black and white monitors. Make sure that there is a enough
contrast between your text and the background of the page. Test your site with
both black -and white and color monitors.
c. Use standard HTML Use
standard tags that all Web browsers can read. Some tags, such as the infamous ,
are not supported by all Web browsers. HTML was designed to be a universal
format outside the bounds of proprietary software and computer languages. Using
standard HTML will ensure that your content can be accessed by all browsers
that visit your site.
d. Design large buttons.
Small buttons providing links can be difficult for visitors with mobility
impairments using specialized pointer adaptive technologies to use. Larger
buttons can make it easier for these visitors to select the links on your page.
e. Include a note about
accessibility Notify your users that you are concerned about
accessibility by including a Web access symbol on your page (see Resources
list), or a statement like the following. Encourage your users to notify you
with their accessibility concerns.
The DO-IT pages form a living document and are regularly
updated. We strive to make them universally accessible. You will notice that we
minimize the use of graphics and photos, and provide descriptions of them when
they are included. Video clips are open captioned, providing access to users
who can't hear the audio. Suggestions for increasing the accessibility of these
pages are welcome.
II. Provide text alternatives to non-text
features such as graphics and image maps.
People who are blind will not be able to view the graphical
features of your Web site. Many people with visual impairments use voice output
programs with text-based browsers (such as Lynx) or graphical browsers with
loading of images turned off. It is imperative that you include text
alternatives to make these graphical features accessible. Here are guidelines
for providing alternative text for various types of features. |
