So whether you are a web developer, designer, or site owner, this guide will provide you with some practical tips and best practices on how to make your website more accessible for everyone.

In the following sections, we'll explore several important topics related to website accessibility, including website navigation, color contrast, and text legibility, alt text for images, keyboard accessibility, video and audio captioning, form and input field accessibility, semantics and HTML markup, assistive technology compatibility and testing, responsive design for mobile accessibility, and website performance optimization for accessibility. Each section will discuss the essential elements and best practices of creating an accessible website, with some examples and instructions on how to implement them effectively.

Website Navigation

Website navigation refers to the menu structure and links used to move between pages, sections, and content on a website. Navigation is one of the most important aspects of web accessibility because it enables users to find and access the content they are looking for.

Accessibility is particularly important for those with disabilities who rely on assistive technologies to navigate websites. According to the World Health Organization, there are approximately 1.3 billion individuals with disabilities globally, which amounts to approximately 15% of the world's population (World Bank, 2019). Therefore, it is essential to ensure that website navigation is accessible to everyone.

Best Practices for Website Navigation Accessibility

  1. Clear and Consistent Navigation: Navigation menus should be labeled in a clear and concise manner so that users can quickly identify them. A consistent layout should be maintained throughout all web pages to minimize confusion. For example, many websites have a menu bar located at the top of the page.

  2. Keyboard Accessibility: Users should be able to navigate the website using only the keyboard or a keyboard alternative, such as a speech recognition program. All navigation links, including drop-down menus, should be accessible by keyboard.

  3. Skip Links: Skip links are important for users with disabilities who use screen readers. Skip links allow users to skip over repetitive navigation links and go directly to the content they are interested in. Skip links should be placed above the main navigation menu for easy access.

  4. Aria Labels: Aria labels describe the role of an element on the screen, such as a button or link, for users of assistive technologies. Aria labels can be added using HTML attributes to help visually impaired users to navigate a site easily. For an example of how to add aria labels check out this W3schools tutorial.


Website navigation is essential for ensuring that your website is accessible to everyone. By following best practices for website navigation, you can make your website more user-friendly, regardless of users' abilities or disabilities.

Color Contrast and Text Legibility

One of the most important aspects of web accessibility is ensuring that content is easy to read and understand for all users. This includes considering color contrast and text legibility.

Color contrast refers to the difference in brightness and color between text and its background. Insufficient contrast can make it difficult or impossible for some users, such as those with visual impairments, to read the text. The Web Content Accessibility Guidelines (WCAG) recommends a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text.

Text legibility, on the other hand, refers to the readability and clarity of text. This can be affected by factors such as font size, style, spacing, and line length. It's important to choose fonts that are easy to read and to use appropriate spacing and line breaks to make content more digestible.

To ensure proper color contrast and text legibility, consider the following tips:

  • Use high contrast colors for text and background. WCAG offers tools to check contrast ratios, such as the Contrast Analyzer, which can help determine whether your color combinations meet accessibility criteria.
  • Avoid using color alone to convey information. For example, don't rely on red text to indicate errors; always provide additional visual or textual cues.
  • Choose fonts that are easy to read, such as sans-serif fonts like Arial or Helvetica. Avoid fancy or script fonts that may be difficult to read.
  • Consider the size of your text. WCAG recommends a minimum font size of 16px for body text and 14px for headings.
  • Use appropriate line spacing and breaks to make content more readable.

By ensuring proper color contrast and text legibility, you can make your website more accessible to all users. For more information and resources on web accessibility, check out the WCAG guidelines and the Accessibility Guidelines for Designers.

Alt Text for Images

Images are an essential aspect of website design. They can enhance the visual appeal of a website and help convey important information. However, images alone cannot fully convey their meaning to visually impaired users. This is where alternative text (alt text) comes in.

Alt text is a written description of an image that provides context and meaning to visually impaired users. It is also used by search engines to understand the content of the image and rank it higher in search results. In fact, websites with alt text are often ranked higher in search results than those without it.

Alt text should be descriptive and concise, providing information about the image's content and purpose. It should be similar to a caption or short description that appears below the image. It is important to note that alt text should not be used as a space for keyword stuffing, which is the practice of using irrelevant keywords to improve SEO. This can harm both the accessibility and the optimization of the website.

Here are some tips for writing effective alt text:

  • Keep it concise: Use as few words as possible while still being descriptive.
  • Be accurate: Accurately describe the content and purpose of the image.
  • Use simple language: Avoid using jargon or overly complex language that may be difficult to understand.
  • Start with most important content: Place the most important information about the image at the beginning of the alt text.
  • Avoid redundancy: If an image and its caption convey the same information, the alt text does not need to repeat it.
  • Avoid using "image of" or "picture of" in the alt text as it is already implied by the context.

For example, instead of "Image of a cat," use "A fluffy orange cat lounging in a sunbeam.”

There are several tools available to help website designers optimize their alt text, such as the Alt Text Checker by Siteimprove, which evaluates the alt text of all images on the website and provides suggestions for improvement.

By making your website images accessible to visually impaired users through alt text, you can improve the user experience and make your content more easily discoverable by search engines.

Keyboard Accessibility

Keyboard Accessibility is a crucial factor in ensuring that your website can be used by individuals with disabilities, who may not be able to use a mouse or other pointing device. According to a survey conducted by WebAIM, 39.3% of respondents reported using a keyboard exclusively to navigate websites. Therefore, it's important to ensure that your website is easy to navigate using only a keyboard.

The following are some guidelines for improving Keyboard Accessibility on your website:

Focus Indicators

Ensure that focus indicators are clearly visible and easy to distinguish. The focus indicator is a visual cue that tells users where they are on a web page. The default focus indicator (a dotted line around the element) can be changed, but it should still be clearly visible.

Keyboard Navigation

Keyboard users should be able to navigate your site in a logical order. Ensure that all interactive elements (links, buttons, form controls) can be reached using the tab key. In addition, ensure that keyboard users can also exit interactive elements using the escape key, and navigate menus using the arrow keys.

Skip Navigation

A “Skip Navigation” link should be provided at the top of the page for keyboard-only users to skip the navigation and go directly to the main content of the page. This can save users time and help them avoid frustration.


Regularly test your website for keyboard accessibility using a keyboard alone. This should be done at all stages of website development to ensure that issues are caught early and can be corrected.

By following these guidelines, you can help ensure that all users, regardless of their ability, can navigate and use your website just as effectively as anyone else. For further information on Keyboard Accessibility, visit the Web Content Accessibility Guidelines (WCAG) created by the World Wide Web Consortium (W3C).

Video and Audio Captioning

Captioning is the process of adding text to a video or audio file that displays a transcript of the audio content, including dialogue, sound effects, and music. Captioning makes it possible for deaf and hard-of-hearing individuals to access video and audio content, and it also enhances the viewing experience for non-native speakers and individuals with auditory processing disorders.

According to the World Health Organization, around 466 million people worldwide have disabling hearing loss, which highlights the significance of captioning in creating inclusive content. In addition, studies indicate that captioning can improve user engagement and retention.

To create accessible video and audio content, consider implementing the following best practices:

Use Accurate Transcripts

It is essential to ensure the accuracy of captions to provide a clear understanding of the content. This involves transcribing the audio content accurately, including any non-verbal cues that are crucial to understanding the context.

Ensure Captions are Synchronized

Captions must appear in sync with the audio, so it is vital to ensure that the timing of the text matches the audio content. This ensures that viewers are not left confused or disconnected from the content due to the delay in the captions.

Use Easy-to-read Captions

The text used in captions should be easy to read, with good color contrast and legibility. The font size should be large enough to ensure that viewers can read the text comfortably without straining their eyes.

In recent years, the use of auto-captioning tools has grown, but it is important to note that these tools may not always provide accurate transcripts. Hence, it is essential to review the captions and make necessary corrections or use professional captioning services.

Implementing these practices will significantly enhance the viewing experience of accessible video and audio content.


Form and Input Field Accessibility

These users rely on assistive technologies to navigate and interact with websites. Failing to make forms and input fields accessible can create barriers and prevent them from completing tasks.

Here are some key factors to keep in mind when designing accessible forms and input fields:


Every form input requires clear and descriptive labels to inform users what kind of information is required. Screen readers must read the label to the user when the input is focused. A well-written label is concise and to the point.

Error messages

One of the most common problems with forms is inadequate error messages. Users with disabilities may have difficulty detecting errors or understanding how to correct them. Error messages should be clear, concise and provide meaningful description of the error, followed by corrective instructions.

Input types

Using proper input types, like date pickers and sliders, can make navigating and filling out forms easier for users with disabilities. Providing enough space between input fields and making sure the input fields are large enough also helps to make filling out forms easier for users including those with motor impairments.

Keyboard accessibility

Good keyboard accessibility ensures that all users can navigate and interact with forms and input fields without a mouse. This is particularly important for users with mobility disabilities. Proper keyboard accessibility can include using the tabindex attribute to let users jump quickly to different parts of the form and assuring that keyboard users can open and close any dropdown menu attached to the input field using the space key.

Examples of accessible forms and input fields

Reviewing some examples of accessible forms can help designers and developers ensure that their forms are easy to use for people with disabilities.

Example 1: Online user registration form
