ACCESSIBILITY TOOLS: Take a Bite Out of Testing with A11ygator

Illustration of Smiling Alligator

Making online content available to every user is the most important requirement for a website. Accessible design takes effort.  You must learn about the specific guidelines and build these rules into your design and content. You must also be prepared to conduct a lot of manual testing.

How can a web developer test a website to get an initial baseline on the items that need to be fixed so they are accessible?

Check out A11ygator, a simplified dashboard where you can type a website URL to check and get an accessibility report.

a11ygator interface

A11ygator uses Pa11y under the hood. You can select the WCAG standard and the wait time – the time to wait before A11ygator actually starts to test, useful for websites that may take some seconds to render the content.

Also, you will get a screenshot of the actual page that A11ygator has tested, plus the ability to download the report in JSON format.

Take A11ygator for a spin.

Illustration of different types of printed books

Here are three tips to follow when creating accessible website content:

– Keep it simple.
– Keep it short.
– Keep it clear.

To accommodate users with learning disabilities, reading disorders, or who speak English as a second language, it is suggested that you write content at an 8th grade reading level.

How can you test the readability of your content?

Use Readability Analyzer, a free online tool that can help you estimate the readability of a passage of text using the Flesch Reading Ease, Fog Scale Level, Flesch-Kincaid Grade Level, and other metrics.

ACCESSIBLE MAPS: Color Advice for Cartography

Color coded countries on world map

Need help determining the correct color contrast for maps?

ColorBrewer to the rescue!

Created by Cynthia Brewer, Mark Harrower and other pros at The Pennsylvania State University, ColorBrewer is a diagnostic tool for evaluating the robustness of individual color schemes in maps.

Full use of the tool can benefit your map designs because colors (even very similar colors) are easy to differentiate when they appear in a nicely ordered sequence (such as a legend). The task of differentiating the colors, however, becomes much harder when the patterns on the map are complex, such as in the lower left corner of the diagnostic map.

Screenshot of ColorBrewer diagnostic color contrast tool

Here are two tests you can conduct with ColorBrewer:

TEST #1: Can you easily distinguish every color in the random section of the map (the lower left)? If you have a ten-class map, you should be able to see clearly ten unique colors.

TEST #2: Within each large band of color on the map, we placed several polygons filled with each map color (‘outliers’). For example, if you have a seven-class map, there will be six outlier colors per band, demonstrating the appearance of all map colors with each as a surrounding color. Can you see each outlier clearly? Do all pairs of outliers in the band look different? If not, perhaps you should choose a different scheme or fewer classes.

ColorBrewer also lets you determine color schemes that are colorblind-safe, print-friendly and photocopy-safe. You can also download a Microsoft Excel file with all 165 color schemes in one master file. Color schemes are also available for use on the web as CSS, JSON, and JavaScript.

Microsoft’s two Accessibility Insights applications are now available as open source code.

The two free tools, Accessibility Insights for Windows and Accessibility Insights for Web, help developers find and fix common accessibility issues early in the software development cycle. They can be used as stand-alone tools or can be integrated through their rules engines into a developer’s build process.

The applications are built on open-source axe technology from Deque Systems, which works with companies to make their websites and mobile apps accessible to people with disabilities. The Accessibility Insights applications are part of Microsoft’s larger inclusion efforts that also involve inclusive hiring and the Department of Homeland Security’s Trusted Tester program.

TOOL: Use the Colorblind Web Page Filter

Types of color blindness. Eye color perception. Vector illustration on isolated background.

Use the Colorblind Web Page Filter tool to select safe colors early in the design process.

Type in your URL, then select one of four color filters from the select menu.

EXAMPLE: Here is a screenshot of the Accessible Website Services Home Page (seen in full color in the left pane) and, in the right pane, how an individual with protanopia (the most common form of color blindness) sees the page:

Comparison test of home page for protanopia color blindness
[Left pane]: Accessible Website Services Home Page
[Right pane]: How an individual with protanopia (red-green color blindness) sees the page

If you only use one filter, use the grey scale filter which will not only point out potential problem areas, but will also let you see more clearly which areas the filter is unable to process.

Use the Color Blind Web Page Filter tool now.
