Accessibility in Web & UX Design

Learn best practices to make web designs accessible to all users, including those with disabilities.

Understanding Web Accessibility

Discover why accessibility is essential for creating inclusive digital experiences that work for everyone.

Designing for Everyone

Web accessibility ensures that websites, tools, and technologies are designed and developed so that people with disabilities can use them. This includes auditory, cognitive, neurological, physical, speech, and visual disabilities.

Accessible design benefits everyone, not just people with disabilities. It improves usability for all users, enhances SEO, and expands your audience reach. By following accessibility standards, you create more robust and flexible products.

Key Accessibility Principles

Explore the four main principles of web accessibility defined by the WCAG guidelines.

Perceivable

Information and user interface components must be presentable to users in ways they can perceive. This means providing alternatives for different senses.

Text alternatives for non-text content
Captions and other alternatives for multimedia
Content that can be presented in different ways
Easier to see and hear content

Operable

Interface components, navigation, and content must be operable by all users. This means making functionality available from a keyboard.

Keyboard accessibility
Enough time to read and use content
No seizures and physical reactions
Multiple ways to navigate

Understandable

Information and the operation of the user interface must be understandable. This means making content readable and predictable.

Readable text content
Predictable operation
Input assistance to help users avoid and correct mistakes

Robust

Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies.

Compatible with current and future user agents
Proper use of HTML elements
ARIA attributes where needed
Error prevention and recovery

Common Accessibility Barriers

Identify and address common barriers that prevent people with disabilities from accessing web content.

Removing Obstacles to Access

Many websites have accessibility barriers that make them difficult or impossible for people with disabilities to use. These barriers can be technical, design-related, or content-related.

By understanding these common barriers, designers and developers can create more inclusive experiences. Addressing accessibility issues early in the design process is more efficient than fixing them later.

Poor Color Contrast
Insufficient contrast between text and background colors makes content difficult to read
Keyboard Inaccessibility
Content that cannot be accessed or operated using only a keyboard
Missing Alt Text
Images without alternative text descriptions for screen reader users

Interactive Accessibility Demo

Experience the difference between accessible and non-accessible design elements with these interactive examples.

Accessibility Comparison

Form Accessibility Comparison

Compare accessible and non-accessible form designs to see the difference.

Accessible Form

Non-Accessible Form

Key Differences: The accessible form has clear labels, proper contrast, visible focus states, and semantic HTML structure. The non-accessible form has poor contrast, small touch targets, and lacks proper labeling.

Color Contrast Examples

See how different color combinations affect readability and accessibility.

Good Contrast (AAA)

This text has excellent contrast against its background, making it easy to read for everyone, including people with low vision.

Ratio: 7:1

Medium Contrast (AA)

This text has acceptable contrast but may be difficult for some users to read in certain lighting conditions.

Ratio: 4.5:1

Poor Contrast (Fail)

This text has insufficient contrast and would be very difficult or impossible for many users to read.

Ratio: 2:1

WCAG Guidelines: Level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Level AAA requires 7:1 for normal text and 4.5:1 for large text.

Keyboard Navigation Comparison

Try navigating these menus using only the Tab key to see the difference.

Accessible Navigation

Non-Accessible Navigation

Try It: Use the Tab key to navigate through both menus. Notice how the accessible menu has visible focus indicators and larger click targets, while the non-accessible menu lacks these features.

Accessibility Best Practices

Implement these guidelines to create more accessible and inclusive web experiences.

Text & Typography

Ensure text is readable and resizable for all users, including those with visual impairments.

Use relative units (em, rem, %) for font sizes
Maintain sufficient color contrast (4.5:1 minimum)
Limit line length to 50-75 characters
Use clear, simple language

Images & Media

Make images and other media content accessible to users who cannot see them.

Provide descriptive alt text for all images
Include captions for videos and transcripts for audio
Use SVG for icons that convey meaning
Avoid images of text for important information

Keyboard Navigation

Ensure all functionality is available through keyboard-only navigation.

Make all interactive elements keyboard-focusable
Provide visible focus indicators
Implement logical tab order
Include skip links for navigation

Semantic HTML

Use HTML elements according to their intended purpose to create a meaningful structure.

Use heading levels in a logical order
Use lists for list content
Use appropriate form elements and labels
Use ARIA attributes when needed
