STOP USING CUSTOMEVENT

Devs should avoid using CustomEvent in JavaScript and instead subclass the native Event class. CustomEvent was only created because subclassing native classes wasn't well-supported when it was introduced, and it forces developers to deal with the awkward `detail` property to access event data. Event subclasses provide cleaner APIs, better TypeScript support, serve as documentation, and guarantee consistent event creation.

CSS CONDITIONALS WITH THE NEW IF() FUNCTION

The new CSS `if()` function can be used to write inline conditional styles instead of separate media queries or style blocks. The function supports three types of queries (style, media, and supports) and uses a condition-value pair syntax like `property: if(condition-1: value-1; condition-2: value-2; else: fallback-value)`. This allows for cleaner, more maintainable code by keeping conditional logic inline with the property rather than scattered across multiple CSS blocks.
