 A comprehensive JavaScript polyfill for the [CSS `if()` function](https://developer.mozilla.org/en-US/docs/Web/CSS/if) that provides support for conditional CSS with `style()`, [`media()`](https://developer.mozilla.org/de/docs/Web/CSS/@media), and [`supports()`](https://developer.mozilla.org/de/docs/Web/CSS/@supports) functions. Now with enhanced support for **multiple conditions within a single if()** and **shorthand property usage**.
