Cross-browser compatibility refers to the ability of a website or web application to function and display consistently across different web browsers. Each browser has its rendering engine, scripting capabilities, and CSS interpretation, which can lead to variations in how a web page is rendered and functions.
Achieving cross-browser compatibility entails understanding web browser differences and implementing solutions to ensure consistent performance.

The following are the significances of delivering cross-browser compatibility:
Enhanced User Experience: A seamless browsing experience across multiple browsers improves user satisfaction, engagement, and encourages repeat visits to your website.
