Accessibility is the practice of making your web content usable and understandable by everyone, regardless of their abilities or disabilities. It is also a legal requirement in many countries and a key factor for user satisfaction and retention. HTML code is the foundation of any web page, so it is important to test it for accessibility issues and fix them as soon as possible. Here are some of the best ways to test your HTML code for accessibility.

1 Use validators

Validators are tools that check your HTML code for errors and warnings, such as missing attributes, incorrect syntax, or deprecated elements. They can help you identify and correct common accessibility problems, such as missing alt text for images, improper use of headings, or lack of labels for forms. You can use online validators, such as the W3C Markup Validation Service, or browser extensions, such as the Web Developer Toolbar, to validate your HTML code.

As an experienced React developer, I've found that ensuring accessibility in HTML code is paramount for creating inclusive digital experiences. One key strategy I advocate for is leveraging validators to scrutinize code for errors and warnings, such as missing alt text or improper heading usage. Tools like the W3C Markup Validation Service and browser extensions such as the Web Developer Toolbar are invaluable for this purpose. Let's prioritize accessibility in our development workflows, championing inclusivity and user satisfaction.

2 Use simulators

Simulators are tools that mimic how your web page would look or sound to different users, such as those who are blind, color-blind, or have low vision. They can help you understand how your HTML code affects the presentation and perception of your content, such as the contrast, readability, or layout. You can use online simulators, such as the WebAIM Color Contrast Checker, or browser extensions, such as the NoCoffee Vision Simulator, to test your HTML code for accessibility.

3 Use screen readers

Screen readers are software applications that read aloud the text and elements on your web page, such as links, buttons, or images. They are used by people who are blind or have low vision to navigate and interact with your web content. They can help you evaluate how your HTML code conveys the meaning and structure of your content, such as the headings, lists, or tables. You can use free screen readers, such as NVDA or VoiceOver, or browser extensions, such as ChromeVox or Firefox Reader View, to test your HTML code for accessibility.

Screen readers like NVDA or ChromeVox let you hear how your site sounds to visually impaired users, highlighting areas where your HTML structure might need improvement.

4 Use keyboard navigation

Keyboard navigation is the ability to use only the keyboard to move around and operate your web page, without using the mouse or touch screen. It is used by people who have physical or motor impairments, or who prefer to use the keyboard for efficiency or convenience. It can help you assess how your HTML code enables the functionality and usability of your web page, such as the focus, order, or feedback. You can use the Tab, Shift+Tab, Enter, Space, and arrow keys to test your HTML code for keyboard navigation.

Keyboard navigation ensures users can navigate without a mouse, vital for those with physical impairments. Test your site using only keyboard controls to ensure seamless navigation.

5 Use accessibility checkers

Accessibility checkers are tools that analyze your web page for compliance with accessibility standards and guidelines, such as the Web Content Accessibility Guidelines (WCAG) or the Section 508 of the Rehabilitation Act. They can help you measure and improve the overall accessibility of your web page, by providing you with a score, a report, and suggestions for improvement. You can use online accessibility checkers, such as the WAVE Web Accessibility Evaluation Tool, or browser extensions, such as the axe Accessibility Checker, to test your HTML code for accessibility.

I am using my VS code to check my HTML accessibility. Moreover, on running or active webpage anyone can inspect that page by right clicking in middle of the page and see how the codes are running in each section. You can use online accessibility checkers, such as the WAVE Web Accessibility Evaluation Tool, or browser extensions, such as the axe Accessibility Checker, to test your HTML code for accessibility.
