Contrast Ratio Requirements for Text in WCAG 2.0 Level AA & AAA
When designing or developing accessible websites, web applications or mobile apps, it may be obvious that text should be very legible. After all, the more difficulty user have reading your information, the less likely they are to interact, engage, purchase or take whatever other action you consider key to success. This is doubly so when developing for persons with low-vision.
An introduction to web accessibility. Tips on how to improve the accessibility of your web sites and apps with CSS.
… a lot of things have changed and CSS now gives us an incredible set of tools to style the web. We went from Verdana to Webfonts, from fixed widths to Responsive Web Design, from table-based layouts to Grid, and we don’t have to use images anymore for borders, fonts or shadows. We have custom properties, Feature Queries, calc() and numerous new units. This of course is only a subset of the great developments of the last years.
While this wide range of properties and endless ways of solving tasks with CSS makes our lives easier, it also creates the potential to worsen the experience for our users. It’s actually possible to make a website inaccessible in just three lines of CSS.
In this post I’ve collected techniques, considerations and approaches that will help you write more accessible CSS. The collection starts with basic concepts and well-known properties and covers some of the newer stuff at the end.
In the end it got way bigger than expected, so here’s a handy menu so you can jump directly to a section that interests you the most:
Last month in my post Source Order Matters I wrote about why we need to consider how the source order of the HTML of a page can affect users when the CSS re-orders the content visually. While I used a recipe as an analogue and cited WCAG conformance rules,I failed to provide specific examples. I prepared one for my talk at Accessibility Camp Toronto, but have since expanded on it with more examples.
I want to make sure that we all understand that the source order versus display order discussion is not unique to CSS Flexbox. It is not unique to CSS Grids. Many developers have been dealing with this (correctly and incorrectly) since CSS floats and absolute positioning were introduced (and even earlier with tabled layouts). As such, I have examples of each in this post (no tabled layouts).
Cascading Style Sheets, or CSS, allow you to modify characteristics of existing HTML elements. All web browsers have a built-in style sheet that defines the default styling for all elements. For instance, when the browser sees the tag, it knows to skip a line and start a new section because that’s what the built-in style sheet instructs it to do. The , , and every other HTML tag is defined in this style sheet; their size, color, position, and other characteristics are all defined within it. When a page author defines their own styles, they can override this built-in style sheet and tell the browser to display elements in a different way.
Left-handed people are surrounded by items that aren’t designed for them. Scissors, golf clubs, desks, video game controllers: it’s a right-hander’s world, and it’s annoying that they don’t take your needs into account.
But imagine moving from annoyed to frustrated, because a product is completely unusable. That’s what it feels like to use the Internet if you have a disability. What acts as a small speed bump for some can feel like a mountain to those with disabilities.
“But what can I do?” you ask. “Accessibility has to be designed and coded.”
True. But it doesn’t stop there. Accessibility is about your image alt text, header design, closed captioning, and other little things that anyone can add to their blog posts, websites, and videos. It’ll make your content more accessible, for everyone—even search engines.

Last week the company announced a partnership with web design firm Dealer Inspire, which makes customer-facing sites for auto retailers, to implement AudioEye’s Ally Toolbar across their entire portfolio.
The move “expands our reach immediately, making it much more efficient to continue our mission to make the most expansive infrastructure in the world accessible to everyone,” Bankofier added.
Even the most well-meaning brand leaders and site designers have too narrow a view of what constitutes disability, he said. It’s not just people who are blind, deaf, or use wheelchairs: people with autism, PTSD, visual impairment, epilepsy, dyslexia or colorblindness all have different needs for digital access. AudioEye’s Ally Toolbar takes all these users into account and allows a person to select precisely the site they need to see.

This page helps you start to assess the accessibility of a web page. With these simple steps, you can get an idea whether or not accessibility is addressed in even the most basic way.
These checks cover just a few accessibility issues and are designed to be quick and easy, rather than definitive. A web page could seem to pass these checks, yet still have significant accessibility barriers. More robust assessment is needed to evaluate accessibility comprehensively.
This page provides checks for the following specific aspects of a web page. It also provides guidance on Next Steps and links to more evaluation resources.
