What is cross-browser compatibility and how to solve CSS compatibility issues between browsers?

Cross-browser compatibility is the ability of a website or application to function correctly and look the same across all popular browsers.

CSS compatibility issues arise due to different browser engines, which interpret styles, support different properties, and use different syntax in various ways.

How to solve:

• Use CSS resets or normalizers (e.g., normalize.css) to align base styles.
• Apply vendor prefixes for properties that require support across different browsers (e.g., -webkit-, -moz-).
• Check property support through sites like Can I Use.
• Use modern build tools and autoprefixers (Autoprefixer) that automatically add necessary prefixes.
• Write fallback styles for new CSS properties.
• Test the site in different browsers and use developer tools for debugging.
