春分巧遇“龙抬头”

The ::first-letter CSS pseudo-element applies styles to the first letter of the first line of a block container, but only when not preceded by other content (such as images or inline tables).

The toLocaleString() method of Temporal.ZonedDateTime instances returns a string with a language-sensitive representation of this date-time. In implementations with Intl.DateTimeFormat API support, this method delegates to Intl.DateTimeFormat and passes this date-time converted to a Temporal.Instant (because Intl.DateTimeFormat cannot directly format a Temporal.ZonedDateTime).
