Web accessibility is the process of designing and building websites, web applications, and digital information so that individuals with disabilities can perceive, comprehend, navigate, engage, and contribute to the web. This includes making web material accessible to people with a variety of disabilities, including visual, auditory, physical, oral, cognitive, linguistic, learning, and neurological.
Why does web accessibility matter?
Web accessibility is crucial for several reasons.
1. Inclusivity
Over a billion individuals worldwide have some sort of disability, which includes visual, hearing, cognitive, and movement impairments. Making your website accessible ensures that this set of web users can utilize the internet and your website successfully.
2. Legal requirements
Besides the moral duty of helping our fellow people, there are legal reasons to incorporate accessibility into your site. Many countries have laws that demand digital access.
3. Better user experience
Accessible websites are easier to use for everyone, including persons with impairments, the elderly, and those who use mobile devices or have slow internet connections.
4. SEO benefits
Many accessibility recommended practices (such as using headers, alt text, and semantic HTML) help with search engine optimization.
5. A wider audience
Making your website more accessible allows it to reach a larger audience and can improve your brand image.
Examples of Website Accessibility
One frequent example is to provide alt text (alternative text) for photos. People with visual impairments or blindness frequently use screen readers—software that reads aloud web information. If an image on a web page lacks alt text, the screen reader cannot describe it to the user, resulting in lost information.
Other examples include:
- Providing adequate color contrast between text and background for persons with impaired eyesight or color blindness.
- Ensure that all functionality may be accessible via keyboard navigation (for people who cannot use a mouse).
- Providing captions or transcripts for multimedia (videos, podcasts) to those who have hearing problems or are hard of hearing.
- Using clear headings and structure in HTML markup to assist persons with cognitive limitations, or using user agents like as screen readers.
Here are seven simple beginning points for understanding the fundamentals of web accessibility
1. Identify the language of the paper.
Help screen readers determine the predominant language used in the document. You can accomplish this easily in HTML: .
2. Use meaningful page titles.
Every page title should accurately and briefly convey the page’s content. Every page should have a distinctive title that sets it apart from others.
3. Add alt tags to photos.
Ensure that all photos provide corresponding alternative text (alt text). The image of your company headquarters, for example, would be defined as <img alt= “company headquarters photo” src=”hq.jpg”>. Without the alt, the image is effectively invisible to visually impaired visitors, search engines, and users who have turned off images.
4. Do not require a mouse.
Many people, notably the elderly and those with limited fine motor skills, are unable to use a mouse. If your website is usable with a keyboard, it will also operate with assistive technology that simulates a keyboard, such as speech input.
5. Provide transcriptions for audio
People who are deaf or hard of hearing will most likely be unable to view your audio recording unless you include a transcript. Additionally, your transcript will be searchable, which will improve your SEO. If you don’t want to do it yourself, consider using a transcription service.
6. Make the link text meaningful.
Users should be able to determine the link’s purpose based on the link itself and/or its context.
7. Check your page for correct tag closing.
Missing open or close brackets might cause problems for screen readers, so be sure your pages are properly formatted. Use this markup validation checker to identify any mistakes.
How can I increase the accessibility of my website?
Here are some accessibility options and best practices:
Use semantic HTML markup: Proper use of headings, lists, links.
Provide alternative text for images: Describe images for screen readers.
Ensure sufficient color contrast: Use tools to check contrast ratios.
Make all functionality keyboard accessible: Ensure users can navigate and interact using only the keyboard.
Label form fields: Use clear labels and instructions.
Use ARIA (Accessible Rich Internet Applications) attributes: For dynamic content and advanced UI controls.
Provide captions and transcripts for multimedia: Videos, audio clips.
Structure content logically: Use headings, lists, and landmarks.
Avoid flashing content: To prevent seizures.
Test your site: Use both automated tools and manual testing with assistive technologies.
