What's Twitter?

Free social networking and micro-blogging service that enables its users to send and read text-based messages of up to 140 characters.

Issues with Twitter.com

From the start, there are accessibility issues.

Can you find 3 items on the main Twitter "Sign in" page that could use improvement?

• Issues with Twitter.com
• Two "click here" links.
• Text links are not underlined.
• Language select dropdown missing submit button.
• Language select dropdown requires JavaScript.
• Poor color contrast (blue on blue).
• "Forgot" what?

Issues with Twitter.com

I'm not even going to mention the headings. At least not on this page...

Issues with Twitter.com

Many web accessibility issues including:

• Not all core functionality is keyboard accessible.
• Poor use of headings.
• Much core functionality requires JavaScript.
• Many more.

Keyboard Access

In Timeline, the keyboard cannot access Favorite, Reply, and Delete links.

Use of Headings

Poor use of headings

• What site is this?
• Is my account name and/or info here?
• Where are the tweets?
• Where is the menu?
• Why is the footer under the heading "Create a new list"?

JavaScript

Twitter.com requires JavaScript. Without it, the user is unable to:

• Favorite a tweet.
• Delete a tweet.
• Access the content under Trending Topics & Followers.
• Perform core actions on Followers and Following pages.
• Exception: Reply to tweet does work without JavaScript.

Other issues with Twitter.com

• Code doesn't validate.
• Code could use better semantics.
• Links unclear.
  • underlines removed
  • :hover pseudo class effects, but no :focus
  • poor color contrast
• Sidebar navigation is inconsistent.
• Form mark-up needs help:
  • Form fields are missing labels.
  • Fieldset tags used without legends.
• Layout width is static, not flexible.
• Custom colors may not be readable.

Keyboard Access

ALL links are keyboard accessible.

And have clear visual focus.

Use of Headings

Ideal use of headings

• What site is this?
• Is my account name and/or info here?
• Where are the tweets?
• Where is the menu?
• In each tweet, the name the author is a heading which greatly improves clarity and navigation for screen readers.

JavaScript

Accessible Twitter is fully functional without JavaScript.

Even works on Lynx, Kindle, etc.

Accessible Twitter uses JavaScript to enhance behavior.

• Progress Enhancement is paramount.

Future Enhancements

A Twitter application, especially an accessible one, is always evolving.

Many enhancements and features are planned including:

• Enhance List functionality with (accessible) Ajax.
• Inline notice and update of new tweets.
• Reply-to-all feature.
• Add optional services for URL shortener and photo uploading.
• Internationalization/multi-language support.

Other Benefits of Web Accessibility & Web Standards

• More usable.
• Better functionality with assistive technology such as text browsers & Braille devices.
• Keyboard accessibility opens gate for many other types of input devices.
• Providing clear, consistent content and navigation benefits those with cognitive impairments (and is more usable in general).
• Use with a mobile device is possible.

Guidelines for Accessible Tweets

• Don't overuse abbreviations.
• Don't overuse hash tags in a tweet; place at end.
• Shorten link URLs.
• Use simple language.
• Place pertinent info before a link.
• Don't use a foreign language without making it obvious (forewarn, enclosing with quotes).
