It's easier when you do it earlier

Web accessibility is easier and cheaper to address early in the development process. Three key strategies help teams shift accessibility left: choosing a CMS that prompts editors for accessible content (like WordPress Gutenberg's contrast warnings), integrating accessibility checks into agile user stories using tools like axe-core alongside manual keyboard and zoom tests, and hiring developers with strong HTML proficiency. The post notes that automated checks only cover 10–30% of WCAG issues, so checklists should complement rather than replace deeper audits.
