Tools to make your website accessible to all users

The World Wide Web without barriers could be an amazing place for everyone. What about your website — does it follow web accessibility guidelines?

Our web team respects accessibility and is always ready to help you make your website accessible. We also love to share tips about creating accessible content and making your images accessible in your team’s everyday content editing practices.

This post will sum up everything you wanted to know about accessibility (a11y for short): what it means to make your website accessible, what accessibility tools are available based on your site’s CMS (Drupal modules and WordPress plugins), and much more.

What does it mean for a website to be accessible?

An accessible website is one that is available to all users regardless of their visual, auditory, cognitive or motor disabilities. It is friendly in every aspect — from color contrast to keyboard navigation.

No user is left behind — the site’s content and UI are easy to comprehend and control in various ways including via assistive technologies.

Why is accessibility important for a website?

  • Website accessibility (a11y) enhances your brand’s reputation because it shows your attitude. According to the Centers for Disease Control and Prevention, roughly one in four adults in the US has some form of impairment. Most people have a friend or acquaintance with a disability, and they appreciate your willingness to follow the guidelines.
  • Make your website accessible and stay protected against possible legal proceedings. The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities. It states that everyone should be provided with equal access and opportunities. There are an increasing number of lawsuits against businesses with inaccessible websites.
  • An accessible site gets a much wider reach. To estimate the figures, consider the above mentioned quarter of the US population and add users with situational issues. These may include broken arms, tired eyes, or even just the need to use your site’s content in a non-native language. In all these cases, users will love your accessible site.
  • By making your website accessible you boost your SEO. Being ready for assistive tools is in many ways similar to being ready for search engines. ALT tags describing the images, clear meta descriptions, video captions, a clear menu hierarchy, and other a11y practices are good SEO practices as well.

How do I add accessibility to my website?

To make your website accessible, you should follow the WCAG (Web Content Accessibility Guidelines). They are the international web standards embracing every aspect of your site’s interaction with users who have an impairment.

The WCAG has been brought to us by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C). They are based on four key principles:

  • Content is perceivable
  • Interface elements are operable
  • Content and controls are understandable
  • Content is robust enough

WAI has also developed ARIA (Accessible Rich Internet Applications Suite). This is a suite of attributes that make interfaces, especially rich and interactive ones, more understandable to assistive devices. WAI-ARIA attributes (roles, states, and properties) can be added to the HTML markup.

Considering all the above, here are some of the key things required from you to make your website accessible:

  • text equivalents for non-text content (ALT tags for images, captions for videos, transcripts for audios, etc.)
  • the proper HTML markup (with the use of WAI-ARIA where necessary)
  • logical layout
  • keyboard controls
  • clear field labels
  • informative error messages
  • clear and simple language
  • informative link texts
  • sufficient color contrasts
  • text resizability
  • adjustable audio volume
  • no auto-playing media
  • more time to complete regular actions

and much more.

Tools to make your Drupal or WordPress website accessible

If your site is built with a CMS, you are in luck . It should already have built-in or add-on plugins to make your website accessible. They are easily installed and configured on your website and take care of various a11y aspects.

Since our agency’s main expertise is Drupal and WordPress, we will list a bunch of helpful extensions for both these CMSs — Drupal modules and WordPress plugins that make your website more inclusive and compliant.
