Top 6 Examples of "uncss in functional component" in JavaScript

// This handles a bunch for us:
                    // autoprefixer: Adds vendor prefixes to CSS, using Autoprefixer.
                    // filters: Converts CSS shorthand filters to SVG equivalent
                    // rem: Generates pixel fallbacks for rem units
                    // pseudoElements: Converts pseudo-elements using CSS3 syntax
                    //   (two-colons notation like ::after, ::before, ::first-line and ::first-letter) with the old one
                    // opacity: Adds opacity filter for IE8 when using opacity property
                    //
                    // We intentionally don't do any minification, since we'd prefer to run uncss first
