A preliminary review may help to quickly identify the scope of problems on your
site. You need to do some some manual checking of representative pages and use
several semi-automatic accessibility checkers.
Select a representative sample of different kinds of pages from your site. You
must include all pages on which people are more likely to enter your site. For
example, your home page.
You should then use a browser such as Internet Explorer or Netscape and look the
pages. Adjusting the browser settings as follows:
-
Turn off images. Check that appropriate alternative text is available
-
Turn off the sound. Make sure audio content is available through text equivalents
-
Use browser controls to change the font-size. Check that the font size changes
on the screen and that you can still use the page at larger and smaller font
sizes
-
Test with different screen resolution, or resize the application window to less
than maximum, to check that you do not need to scroll horizontally
-
Change the display colour to grey scale (or print out page in grey scale or black
and white) and see whether the colour contrast is adequate
-
Don't use the mouse. Instead, tab through the links and form controls on a page
and make sure that you can access all links and form controls. Check that the
links clearly indicate where they go
Next, use a voice browser (such as Home
Reader) and a text browser (such as Lynx)
and check:
-
The same information is available through the voice or text browser as is available
through the normal browser
-
The information is presented in a meaningful order if read serially
Use some of accessibility evaluation
tools and note any problems indicated by the tools. You can then correct the
errors.
