accessibility with your websites
Accessibility Misnomers (#1)
1.
If I can read my site, it’s accessible. People who are sight-disabled
can just have someone read the information to them.

ACCESSIBLE WEB CONTENT
• Note taker
• Properly structured
• Extra time on a test
• Text alternatives for images and
multimedia
• Sign language interpreter

screen magnifier)
• Proper color contrast

Accessibility Creates Access
Who Accesses Your Sites?
A Broad Spectrum of People! Including:
• Sight impaired
• Hearing impaired
• Mobility impaired
• Cognitively impaired
Introducing WCAG 2.0

Getting to Know WCAG 2.0
http://www.w3.org/TR/WCAG20/#guidelines
Guidelines for Perceivable
• 1.1 Provide text alternatives for any non-text content so that it can be
changed into other forms people need, such as large print, braille,
speech, symbols or simpler language.
• 1.2 Provide alternatives for time-based media.
• 1.3 Create content that can be presented in different ways (for
example simpler layout) without losing information or structure.
• 1.4 Make it easier for users to see and hear content including
separating foreground from background.

Low-hanging Fruit of Web Content
• Structured Headings
• Alternative Text
• Clear Hyperlinks
• Color Contrast
• Name Form Fields
• Accessible Videos
Headings
• h1, h2, etc.
• Provide structure, like an outline
• Use only one h1 per page
• Can use CSS to format them
Table: Addressing Alternative Text
Type of Image
Appropriate Alternative Text
Simple/Decora
tive
A few words to replace image
OR
“ “ (null alt text) – must be done in the HTML
Hyperlink
A few words to replace image, also indicate to where it
links
Complex image
A few words to replace the image, plus a long description
in a separate text document. Link to text document.
Writing Hyperlink Text
• Where is the link going?
◦ Name of site
• What will be viewed?
◦ Why user is going
• What else happens?
◦ If link opens in a new window, say that in the
hyperlink text
Color Contrast
Avoid Conveying Information with Color
Name Form Fields
Accessible Videos
Misnomers Reframed (#1)
If I can read my site, it’s accessible to me.
People who are sight impaired can use
the structural design I built in to navigate
the content using a screen reader.
Misnomers Reframed (#2)
We have a Disabled Student Services
office, they’ll let me know when I
have a student who needs an
accommodation. But, I’ll make sure
all of my students can access my
online content.
Misnomers Reframed (#3)
Branding elements, like a logo, don’t
make for an accessible site. Following
the Web Content Accessibility
Guidelines makes a website
accessible.
Misnomers Reframed (#4)
Granted, because it seems like there’s
a lot to do, accessibility may seem
hard, but taking it one step at a time
makes it more manageable. I’m finding
that once I start applying a new
concept, it starts to come
automatically.
Misnomers Reframed (#5)
Creating accessible web content does
matter. It’s something we do to
remove what often turns out to be
barriers for many people when they
visit websites.
