Content creators want everyone to be able to access their work, and businesses want their products available to as many people as possible. This useful web accessibility checklist, created by Vox Media, outlines specific criteria for designers, engineers, project managers, quality assurance, and editorial teams to build accessible content. Experienced readers can use the checklist with their teams to ensure no one misses out on what they create. Readers with less experience in accessibility will learn from the brief explainers under each item, which summarize the how and why of each criterion and link to sources of further information. At the bottom of the checklist, users will find markdown and plain text formats to copy and paste into documents, Slack, Trello, or other project management tools. Users who scroll to the Tools section will find several resources to help complete the items in the checklist, such as color blindness simulators and a color contrast analyzer. Readers looking to learn more about accessibility should scroll to the Resources section for websites, courses, newsletters, and book recommendations on the subject.
