iamvdo/postcss-opacity

This project is a PostCSS plugin that adds support for legacy browser opacity alternatives, including IE 8, IE 5-7, Safari 1.X, and Netscape. It's designed for developers who need to ensure their CSS works seamlessly across older browsers, particularly when using the `opacity` property. The plugin automatically generates the necessary vendor-specific filters and properties, making it easier to maintain cross-browser compatibility.
