What is cross browser?
Cross-browser refers to the ability of a website, HTML construct, application, or even client-side script to work in different environments that provide the functionality it needs. Similar to how a cross-platform program can run on multiple computing platforms, cross-browser websites can run on multiple browsers.
One way to ensure compatibility is to use a basic coding method that compensates for incompatibilities between different browsers. However, if this is not possible, the developer must adapt the code accordingly. Cross browser compatibility is very important for the proper functioning of web applications.
