Frequently Asked Questions about Web Accessibility

Understanding WCAG Standards

The Web Content Accessibility Guidelines (WCAG) are international recommendations for making web content more accessible to people with various types of disabilities. They include guidelines on how to make web content accessible to people with visual, auditory, motor, or cognitive impairments. WCAG is divided into three levels of compliance: A, AA, and AAA, with AAA being the highest level of accessibility.

The color contrast ratio is a measure used to determine the readability of text and graphic elements on a given background. According to WCAG standards, a minimum contrast ratio is required to ensure that texts are readable by people with visual impairments. The ratio varies depending on the level of WCAG compliance, with higher requirements for small text and normal text.

To choose color combinations that comply with WCAG, it is important to use contrast checking tools to ensure that the contrast between the text (or graphic element) and its background meets the minimum required ratios. It is advisable to favor colors with sufficient difference in brightness and saturation. In case of doubt, online tools can help test and adjust color combinations to meet WCAG compliance criteria.

WCAG addresses color blindness and visual impairments by recommending inclusive design practices. This includes the use of contrasting colors, providing text alternatives for graphic elements, and avoiding conveying important information through color alone. WCAG guidelines also encourage the use of adaptive font sizes and clear styles to facilitate reading by people with visual impairments.

To apply WCAG to dynamic and interactive content, it is important to ensure that this content is accessible via keyboard and that state changes are communicated to users, including those using screen readers. Animations and movements should be designed in a way that does not cause adverse reactions in sensitive users. Additionally, interactive forms should provide clear feedback on errors and facilitate user correction of errors. It is also essential that any dynamic content, such as real-time content updates, be accessible and not disrupt the user experience for those using assistive technologies. Finally, interactive interfaces should be designed considering different modes of interaction, such as touch, voice, and keyboard, to ensure full accessibility.
