What does cross-browser compatibility ensure?

Cross-browser compatibility ensures that websites function correctly across different web browsers. This concept is essential because users access the internet using a variety of browsers, such as Chrome, Firefox, Safari, and Edge, each of which has its rendering engines and may interpret HTML, CSS, and JavaScript differently. Ensuring cross-browser compatibility means that a website’s layout, functionality, and features work consistently, providing a uniform experience regardless of the user's browser choice. This capability promotes inclusivity and accessibility, allowing a wider audience to interact with the website seamlessly.

The other concepts, while related to web development, do not define cross-browser compatibility. For example, focusing solely on visual appeal across devices does not account for functional issues that might arise in different browsers. Additionally, the idea that websites function only in Google Chrome contradicts the goal of compatibility, which is to support multiple browsing environments. Finally, while faster loading times in certain browsers might enhance user experience, it does not address the fundamental aspect of ensuring that a website operates correctly across various platforms.
