When building for the web, I use a combination of Lighthouse (Chrome Dev Tools audit) and the axe extension to do a first pass at validating the accessibility of the site/app/etc. Of course, there's an art to this as well.<p>For example, there's a significant number of individuals with cognitive disabilities [0], so using a combination of axe to ensure heading structure is logical and accurate, plus spending the time to ensure concise and accessible content, is an approach that I take often.<p>a11y is more than WCAG contrast ratios :)
