  • [Перевод] Размытая граница между состояниями CSS и событиями JavaScript CSS “слушает” нас. Нет, не в буквальном смысле . Суть в том, что в CSS появляется все больше псевдоклассов, которые позволяют реагировать на события JS без необходимост

#pseudoclass across platforms

every network with a public tag surface

Follow #pseudoclass straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

X (Twitter) ↗Instagram ↗TikTok ↗Facebook ↗LinkedIn ↗YouTube ↗Threads ↗Bluesky ↗Mastodon ↗Reddit ↗Pinterest ↗Tumblr ↗

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/pseudoclass
