Question 5 How can a designer help a person
that has a limited vision so that he or she can
read the website?
15
Designers Job
Answer 5 Readers whose vision is limited may
set their browsers to display text in a certain
size or typeface that they find particularly
legible. Relative font tags, such as ltBIGgt
and ltSMALLgt can help your readers to focus on key
points of content,while enabling them to gloss
over less important items.

Question 6 How can a designer make it easier
for a colorblind person to read?

Designers Job
Answer 6 Color-blindness comes in a wide
variety of shapes, sizes, and severities. Most
often, color blindness takes the form of an
inability to distinguish various shades of reds
and greens. In extreme cases, most greens and
almost all reds can appear to the reader as
shades of gray. So be carefull when using reds
and greens in your website!

Question 7 Can blind people interact on a
website?
19
Designers Job
Answer 7 Ensure that moving, blinking,
scrolling, or auto-updating objects or pages may
be paused or stopped. Movement can also cause
such a distraction that the rest of the page
becomes unreadable for people with cognitive
disabilities. A voice can lead the blind person
on the website by giving spoken comment by audio.
