Web Accessibility: Best Practices

Web Accessibility

Web accessibility has become increasingly important in recent years as businesses and organisations strive to create more inclusive online experiences for all users. In this article, we will discuss best practices for web accessibility and explore why it is so crucial for businesses to prioritise this issue.

What is Web Accessibility?

Web accessibility refers to the practice of designing websites and web applications in a way that makes them accessible to all users, including those with disabilities. This includes visual, auditory, and physical disabilities, as well as those with cognitive or neurological impairments.

Why is Web Accessibility Important?

Ensuring web accessibility is not only the right thing to do, but it also makes good business sense. By making your website more accessible, you can reach a wider audience and improve the user experience for all users. In addition, there are legal requirements for web accessibility in many countries, and failure to comply can result in fines and lawsuits.

Best Practices for Web Accessibility

Here are some best practices to keep in mind when designing and developing accessible websites and web applications:

Use Appropriate Headings and Structured Content

Using appropriate headings and structured content is crucial for making your website more accessible. Headings help users understand the organisation of the content on a page, and assistive technologies such as screen readers can use them to navigate the page. Use H1, H2, H3, and H4 headings appropriately to structure your content.

Provide Alternative Text for Images

Alternative text (alt text) is a brief description of an image that is read by screen readers. It is important to include alt text for all images on your website, as this allows users who are blind or have low vision to understand the content of the image.

Use Descriptive Link Text

When creating links, it is important to use descriptive link text that accurately describes the destination of the link. Avoid using generic text such as “click here” or “read more,” as this can be confusing for users who are using assistive technologies.

Ensure Keyboard Accessibility

Some users may not be able to use a mouse or other pointing device to navigate your website. Make sure your website can be navigated using only the keyboard, and that all functionality is available using keyboard commands.

Provide Captions and Transcripts for Multimedia Content

Multimedia content such as videos and audio files should be accompanied by captions and transcripts. This ensures that users who are deaf or hard of hearing, as well as those who may not be able to play audio, can still access the content.

Use High Contrast Colours and Clear Fonts

Using high contrast colours and clear fonts can help users with low vision or color blindness to read your content more easily. Make sure your font is at least 14pt and avoid using thin or decorative fonts.

Avoid Flash and Other Inaccessible Technologies

Flash and other technologies that are not accessible to all users should be avoided. Instead, use HTML5 and other modern web technologies that are accessible and widely supported.

Provide Clear and Consistent Navigation

Clear and consistent navigation is essential for all users, especially those with disabilities. Make sure your website navigation is easy to understand and consistent across all pages. Use descriptive labels for navigation links and avoid using symbols or icons without text labels.

Use ARIA Roles and Attributes

Accessible Rich Internet Applications (ARIA) roles and attributes can be used to make dynamic content more accessible. Use ARIA roles and attributes to describe the function and purpose of interactive elements on your website, such as menus, sliders, and pop-ups.

Ensure Forms are Accessible

Forms on your website should be designed with accessibility in mind. Use clear labels for form fields, and provide instructions for completing the form. Make sure form controls are keyboard accessible, and use error messages that are easy to understand.

Consider Colour Blindness

Colour blindness affects approximately 1 in 12 men and 1 in 200 women worldwide. Consider how your website design looks to users with colour blindness, and make sure that important information is conveyed through other means, such as text or symbols.

Provide Users with Control

Users with disabilities may have specific needs or preferences when it comes to how they access and interact with your website. Provide users with control over how your website is presented, such as the ability to adjust font size or contrast.

Test Your Website for Accessibility

Testing your website for accessibility is an essential step in ensuring that it is accessible to all users. There are a variety of tools available for testing website accessibility, such as the WAVE Web Accessibility Evaluation Tool and the AChecker Accessibility Checker.

Educate Yourself and Your Team

Web accessibility is an ongoing process, and it is important to stay up-to-date with best practices and new developments in the field. Educate yourself and your team on web accessibility, and make it a priority in all aspects of your website design and development.


Web accessibility is a critical issue that businesses and organisations cannot afford to ignore. By following best practices for web accessibility, you can create a more inclusive and user-friendly online experience for all users.
