Why is cross-browser compatibility important?

Cross-browser compatibility is crucial because it ensures that websites function properly and consistently across different web browsers. Web browsers, such as Chrome, Firefox, Safari, and Edge, sometimes interpret HTML, CSS, and JavaScript differently. This variation can lead to differences in how a website appears and performs on different platforms. By achieving cross-browser compatibility, developers can make sure that all users, regardless of their chosen browser, have a similar experience when visiting a site. This includes proper rendering of layout, functionality of interactive elements, and an overall user-friendly experience, which is essential for user satisfaction and retention.

While reducing server load, making websites load faster, and enhancing SEO performance are important considerations for web development, they do not directly address the primary goal of ensuring a consistent and functional experience across various browsers.
