1 Web Accessibility

2 Accessibility Webaim This is a pretty prolific site that has a cool little toolbar to install to your bowser. It’s called Wave. It’s a great tool, but it is also easy to fool. Just because your site passes with no accessibility errors, does not mean it’s accessible. It only means it technically meets minimum requirements. Colorblindness Simulators WeAreColorBlind – This tool is pretty high level, but it gives you a good idea about the need for consideration to you color blind audience. Color contrast is important, and there are a few great examples of the right and wrong way to display your data, when considering a color blind audience.

9 Headings For All Docs… Not Just Web

10 Headings even (especially) in PDF!

11 Speaking of PDFs…..

12 Create Accessible PDFs Not all PDFs are equal: – Image PDFs – PDFs with text, but no structure – Tagged PDF (the only accessible type) Can create an accessible PDF from scratch – Using a tool that supports tagged PDF (e.g., Word) – Save as tagged PDF Can fix an inaccessible PDF using Adobe Acrobat Pro

13 Fixing PDFs in Acrobat Pro 1. Convert to text (if needed) 2.Add tags to document (if needed) 3.Touch up reading order, add alt text to images 4.Check/correct headings and other tags 5.Create links from URLs (if needed) 6.Define document language 7.Run an accessibility check

14 PDF Accessibility Resources Includes workflows for: – Making a PDF accessible from scratch – Exporting from Word to tagged PDF – Repairing and creating inaccessible PDFs and PDF forms using Acrobat Pro PDFs are great for documents where: Appearance is critical. Document must be the same across all platforms. Security is critical. Document requires encryption, digital signatures, watermarks, etc.

15 Mark Up Tables Appropriately Include markup that clearly communicates the relationship between table headers and the cells within their scope:

16 Color Contrast Checker WCAG 2.0 Level AA: – Contrast ratio of 4.5:1 for normal text – or 3:1 for large text (18 pt or 14 pt bold) WCAG 2.0 Level AAA: – Contrast ratio of 7:1 for normal text – Or 4.5:1 for large text

17 Color Contrast Example

18 Respect white space Space between lines Space between paragraphs Can help users who have difficulty tracking text horizontally. Contributes to a cleaner, more aesthetically pleasing interface for everyone.

21 Think Twice About the Words You Choose Word length and sentence complexity have an effect on the ability of certain individuals to decode the words on a page. Juicy Studio Readability Test: Struggling with Understandability:

22 Make Text Easier to Read Understandable  “easier to read” Manipulated  Changed Subsequently  Later “Testimonials from individuals with disabilities…”  “People with disabilities talk about…”
