Which feature helps improve website accessibility for users with disabilities?

Improving website accessibility for users with disabilities is crucial, and one of the most significant features that directly impacts this is the contrast between text and background. High contrast between these elements enhances readability for users, particularly those who have visual impairments. This includes individuals with low vision or color blindness who may struggle to distinguish between text and background colors that are too similar.

Good contrast ensures that text stands out clearly, making it easier for users to read content on the website. In contrast, options such as audio elements or rich media, while beneficial in some contexts, may not specifically address visual accessibility issues. Similarly, complex layouts can hinder navigation and comprehension, especially for users who rely on assistive technologies. Therefore, maintaining a strong contrast ratio is a fundamental principle in web design for creating accessible content, making it the best choice in this context.
