How does Liferay ensure accessibility in frontend development?

Liferay emphasizes accessibility in frontend development by providing built-in ARIA (Accessible Rich Internet Applications) roles and adhering to WCAG (Web Content Accessibility Guidelines) standards. This approach is crucial because ARIA roles enhance the accessibility of web content, conveying the semantics of user-interface components to assistive technologies like screen readers. Compliance with WCAG standards ensures that the website is designed to be perceivable, operable, understandable, and robust for users with disabilities.

Incorporating these elements into Liferay’s framework facilitates the creation of accessible applications that cater to a wide range of users, including those with visual, auditory, or cognitive impairments. This commitment to accessibility not only enhances user experience but also aligns with best practices in web development.

The other options do not support effective accessibility practices. Focusing solely on visual design elements would ignore the needs of users relying on screen readers or other assistive tools. Limiting content to text only would not consider interactive elements that require proper accessibility attributes. Avoiding external libraries may reduce reliance on potentially problematic code but does not inherently promote accessibility. Thus, the provided answer highlights the correct and comprehensive approach Liferay takes towards ensuring accessibility in frontend development.
