Web accessibility is the practice of designing and developing websites that can be used by people with disabilities. This includes individuals with visual, auditory, physical, cognitive, and neurological impairments. By ensuring that websites are accessible, we can ensure that everyone has equal access to the information and services available online. Here are some basics of web accessibility that every website owner and developer should know:

  1. Use semantic HTML

Semantic HTML is the foundation of web accessibility. It means using HTML elements that convey meaning and structure to both humans and machines. For example, using <h1> to indicate the main heading of a page, <p> for paragraphs, and <ul> and <ol> for lists. This helps assistive technologies, such as screen readers, to understand the content and convey it to users with disabilities.

  1. Provide alternative text for images

Alternative text, also known as alt text, is a brief description of an image that can be read by screen readers. It is essential for people with visual impairments who rely on screen readers to navigate the web. Alt text should describe the content and function of the image, such as “a red apple on a white plate” or “a button that says ‘submit’.”

  1. Use color with care

Color is an important aspect of web design, but it can also create barriers for people with visual impairments. Always ensure that text is readable against its background color. Avoid using color alone to convey information, as colorblind individuals may not be able to distinguish between different colors. Instead, use other visual cues, such as icons or patterns, to convey information.

  1. Provide keyboard accessibility

Many people with disabilities rely on a keyboard to navigate the web. This includes individuals with physical disabilities who may not be able to use a mouse or touchpad. Ensure that all functionality can be accessed using a keyboard alone, and that users can easily navigate through the website using the tab key.

  1. Ensure audio and video content is accessible

Audio and video content should be accessible to people with hearing impairments. This can be achieved by providing captions or transcripts for videos and audio descriptions for visual content. It is also important to ensure that audio and video players are keyboard accessible, so that users can control them without a mouse.

Web accessibility is crucial for ensuring that everyone has equal access to information and services online. By implementing the basics of web accessibility, website owners and developers can make their sites more inclusive and welcoming to people with disabilities.
