How does Autoprefixing aid in ensuring cross-browser compatibility?
- Autoprefixing adds vendor-specific prefixes to CSS properties, ensuring compatibility with various browsers.
- Autoprefixing automatically generates alternate versions of your styles for different browsers.

- It converts JavaScript code to CSS for browsers that do not support modern JavaScript.
Autoprefixing is the process of adding vendor-specific prefixes to CSS properties to ensure cross-browser compatibility. It automatically generates CSS rules with the necessary prefixes, like -webkit-, -moz-, or -ms-, making sure that your styles are correctly interpreted by different browsers. This helps avoid the need for writing separate CSS rules for each browser.
