How do you solve cross-browser compatibility issues? How can you tell in advance if a CSS property will work in the target browsers?

To address cross-browser compatibility issues, I use several approaches:

• Checking CSS property support on sites like Can I use, where you can see which browsers and versions support a particular property.
• Using Autoprefixer in the build process, which automatically adds vendor prefixes for properties that require them in different browsers.
• Writing fallback solutions for new CSS properties, for example, if I use grid, I add alternatives with flexbox.
• Testing in real browsers and using emulators.

Example of using Autoprefixer in a project with PostCSS:

// postcss.config.js
module.exports = {
  plugins: [require('autoprefixer')]
}

This way, you can anticipate whether a CSS property will work by checking its support on caniuse.com and using tools for automatic browser adaptation.
