But how will you know whether your website is really accessible or not? Simple, many tools, simulators, and checkers are available on the internet which you can use to determine the level of accessibility of your website and make changes accordingly. Some of them are free and may give basic results, while others are paid but will give results in details.

• Color Contrast Checker: Color influences the readability of people. Here you have to enter the background color and font color to determine whether the contrast between these two meets the WCAG standards.

Browsers also have toolbars that help in accessibility. The WAVE toolbar from WebAIM works on Firefox and helps identify common accessibility issues via the WAVE’s inline evaluation functionality. Paciello Group has a toolbar for the good old Internet Explorer. The Chrome Accessibility Developer Tools has an extension that adds accessibility sidebar pane in the Elements tab and an accessibility audit. Juicy Studio has a Firefox toolbar that helps identify ARIA roles, color contrast, and data tables.

Tenon.io is an Automated Accessibility Testing coverage for a broad range of accessibility best practices. Deque System has aXe (The Accessibility Engine), a lightweight Javascript library which executes automated accessibility testing in any testing framework or browser.

Following are not any tester, checker or simulation tool, but the all-important rules, guidelines, etc. do refer them for more information and enriching yourself regarding everything about accessibility:

• WebAIM is the ultimate resource for learning all about accessibility and studying your website.
