Polyfills Memes

Frontend devs getting hyped about the latest CSS feature only to realize it has "Limited availability" and doesn't work in "some of the most widely used browsers" is basically the web development circle of life at this point. You find this amazing new feature that solves a problem you've been hacking around for years, start planning how you'll refactor your entire codebase, and then BAM—browser support slaps you back to reality. The title references the recent wave of exciting CSS features like @property (CSS custom properties with types), @container (container queries), and interpolate-size (smooth transitions for intrinsic sizing) that all went through this same "ooh shiny!" to "oh wait, browser support" pipeline. It's like being a kid in a candy store where half the candy is behind a glass case labeled "Available in 2-3 years." Fun fact: The "Baseline" term refers to the Baseline initiative by browser vendors to identify features that work across all modern browsers. Not being Baseline basically means you'll need polyfills, fallbacks, or just... patience.
