Think of using headers as similar to
creating an outline. Headers provide
a hierarchy for your text and organize
information into groups.
Graphic elements, such as horizontal lines, are not always clear signals
for new sections, especially to someone who cannot see the screen. Go

to make navigating other pages easier.
Also, do not create webpages that are
too large for the screen and require
horizontal scrolling. Keep in mind

to view your website using browser
windows of various sizes.

Keep in mind that tools such as roll-overs and dropdown menus are difficult to use without a mouse. Because
these features use Java script, most
screen readers cannot interpret the
information. Cascading style sheets
(CSS) can improve the usability of the
Java script, but incorporating them
