The World of Website Accessibility

February 28, 2017

When building your website, it’s important to account for accessibility, designing your product so that users with disabilities can access it.

Your business should care because the number of people affected by disabilities worldwide is large. The World Bank Group estimates that one billion people – 15% of the world’s population – have some level of disability.

Disabilities impact people’s capability to use technology. Interactive Accessibility states the following facts:

  • 19.9 million (8.2%) [of users] have difficulty lifting or grasping. This could, for example, impact their use of a mouse or keyboard.
  • 8.1 million (3.3%) have a vision impairment. These people might rely on a screen magnifier or a screen reader, or might have a form of color blindness.
  • 7.6 million (3.1%) have a hearing impairment. They might rely on transcripts and/or captions for audio and video media.”

As the numbers indicate, accessibility matters. Thus, we recommend that you design your product with accessibility in mind to:

  1. Comply with the law
  2. Expand your audience
  3. Create better usability
  4. Create an equal opportunity for users, regardless of their disabilities, to access information.

The Must Haves: Coding Best Practices for Accessibility

How good is your code base? Even if you aren’t considering accessibility, you should be
following a few basic guidelines. These will ensure that your code is sound:

4.1.1 – Parsing

Bad HTML throws off screen readers. Ensure your website has no major code errors by ensuring your HTML is not broken.

3.1.1 – Language of Page

Content developers should ensure that the web page presents text and other content correctly, in a language understood by screen readers.

2.4.4 – Link Purpose (In Context)

Are your hyperlinks clearly demarcated? Do links have consistent descriptions? Consistent, reliable linking allows users to navigate with ease.

2.4.3 – Focus Order

Ensure that users can navigate sequentially through content and encounter information logically. This affects keyboard accessibility.

1.3.2 – Meaningful Sequence

Meaningful sequence ensures that users with assistive technology encounter content in the intended order.

If budget allows, you’d want to complete all of the Must Haves and more, depending on the bottom line of your specific case.
