Exploring the Best Practices for WCAG Compliance

In a world increasingly reliant on the internet, having an accessible website is not just a nicety, it’s a necessity. But knowing how to make your website accessible takes some work. This is where the Web Content Accessibility Guidelines (WCAG) come into play. But what exactly is WCAG, and how can you stay compliant?

What is WCAG?

The Web Content Accessibility Guidelines (WCAG) are a set of recommendations developed by the World Wide Web Consortium (W3C) to make web content more accessible to people with disabilities. These guidelines are designed to provide a single shared standard that meets the needs of individuals, organizations, and governments internationally.

Each guideline in WCAG relates to a certain aspect of web accessibility, for example, time-based media, text alternatives, and input assistance. Success criteria exist for each guideline, outlining how to reach different standards, or levels, of conformance. The lowest level of conformance is A and the highest is AAA, with most organizations aiming to achieve AA, a mid-level conformance. You can learn more about what the different level of WCAG are here.

But regardless of the standard you are striving for, understanding WCAG is essential for any modern organization.

The Key Principles of WCAG

At the heart of WCAG are four foundational principles, denoted by the acronym POUR: perceivable, operable, understandable, and robust. Each principle acts as a different pillar of accessibility, ensuring that web content is within reach of all users, regardless of their abilities.

1. Perceivable

According to WCAG, all web content must be perceivable. This means that text on websites should be easily readable, images should be clearly visible, and all content should be compatible with a screen reader so that it can be read aloud for those with visual impairments.

2. Operable

Operable refers to the user interface and navigability of a website. This key principle implies that users must be able to interact with the website interface, whether they are using a mouse, keyboard, or assistive technologies. For instance, those who are unable to use a mouse due to motor impairments may need to rely on using their keyboard to browse websites. Various website elements, like buttons and links, must therefore be reachable by keyboard alone.

3. Understandable

The third principle, understandable, is all about how easy a website is to understand, both in terms of its content and the functionality of its interface. Things like forms should have clearly labelled fields with explanations if necessary, and buttons or drop-down menus should follow a comprehensible logic.

4. Robust

Finally, robust refers to a website’s interpretability, meaning the ability for its elements to be read by a variety of different agents, including assistive technologies. The use of semantic HTML here helps ensure that content is clearly distinguishable for assistive technologies, as well as browsers, and can be interpreted correctly across different devices and platforms.

Best Practices for WCAG Compliance

Achieving WCAG compliance involves adhering to a series of best practices, each of which embodies the POUR principles. This section explores how exactly these best practices raise accessibility standards, who they benefit, and how compliance with WCAG can be achieved. Some of these best practices for WCAG include:

  1. Accessible image alt text
  2. Provide captions for multimedia
  3. Keyboard accessibility
  4. Accessible font type and size
  5. Clear color contrasts
  6. Accessible form fields
  7. Mobile accessibility
  8. Compatibility with assistive technologies
  9. Descriptive anchor text
  10. Interactive elements easily identifiable

2. Provide Captions for Multimedia

Captions are essential for users who are deaf or hard of hearing. They provide text versions of spoken content and other important sounds in videos. For example, a YouTube video explaining how to bake a cake should include not only captions for all spoken baking instructions, but descriptions of significant sounds too, like the timer going off or the whir of a blender.

3. Keyboard Accessibility

For those with motor impairments, using a mouse might not be possible, hence the importance of keyboard accessibility when it comes to designing your website. All website functionalities should be reachable via keyboard alone, meaning elements like forms, buttons, and links must be navigable with the Tab key, Spacebar, and Enter button, without the need for any cursor movements.

4. Accessible Font Type & Size

Part of complying with WCAG is ensuring that fonts are easy to read, and that text can be resized up to 200% without loss of content or functionality. Clear, legible fonts, like Arial or Verdana, should be used in place of more decorative fonts, as this gives those with visual impairments and reading difficulties a better chance of perceiving the content presented to them. Tools, like Recite Me’s accessibility toolbar, allow users to customize website content in the most suitable way for them, which includes altering font styles and sizes, among other things.

5. Clear Color Contrasts

Ensuring a high contrast ratio between graphical elements and their background is an important part of making websites readable and understandable, particularly for users with visual impairments such as color blindness. Black text on a white background, for example, provides a clear contrast, making the text stand out so that it is easy to read. Light gray text on a white background, on the other hand, does not stand out and is difficult to read as a result. It may sound simple, but always being aware of color contrasts will help you and your organization stay WCAG compliant.

6. Accessible Form Fields

To remain WCAG compliant, form fields should be clearly labelled and instructions provided where relevant. Other than making the form itself understandable, conveying the purpose of each field helps users with screen readers, who miss out on visual context, to better comprehend the form. Instead of a generic “Submit” button, for example, using a specific label like “Submit Your Application” helps users know what they are submitting and at which point of the form they are at.

7.  Mobile Accessibility

Given how many phone and tablet users there are in the world today, mobile accessibility is essential. It’s all well and good having an accessible website, but if that same accessibility isn’t available on mobile devices, then a large portion of the population are still being excluded. Many website builders nowadays include features which allow creators to switch between desktop view and mobile view, meaning you can check that buttons are appropriately sized and text is readable without horizontal scrolling.

8. Compatibility with Assistive Technologies

Assistive technologies examples such as screen readers and braille readers, help individuals with disabilities like visual impairments to access all the same elements of a website’s functionality. But for assistive technologies to work, websites must be compatible with them. The use of semantic HTML links, like <nav>, <header>, and <footer>, make it easier for assistive technologies to interpret the website content, translating it more accurately into verbal content. A machine might be able to better distinguish the body of an article from its header, for example, if semantic HTML links are used, improving your website’s screen reader accessibility as a result.

9. Descriptive Anchor Text

All links displayed on a website page should have descriptive anchor text that clearly indicates the destination or purpose of the link. Anchor text that reads ‘click here’, for example, is a lot less clear than ‘read our accessibility guidelines’. For those that use screen readers, having descriptive links like this supports navigation, helping you to know which page you are visiting without clicking on every link.

10. Interactive Elements Easily Identifiable

Part of WCAG compliance is making sure that buttons, links, and other interactive elements are easily distinguishable from non-interactive content. This is because the clear identification of interactive elements helps users with cognitive disabilities, and those using screen readers, to navigate the site more effectively. Some easy ways to do this include underlining linked text or ensuring that buttons have distinct colors or borders compared to other elements.
