Support summary

Notes

The spec says that both letters of digraphs which are always capitalized together (such as "IJ" in Dutch) should be matched by ::first-letter, but no browser has ever implemented this.

  1. Excludes punctuation immediately after the first letter from the match. (The spec says it should be included in the match.)
  2. Acts like the first character is always a letter even when it's not. For example, given "!,X;", "!," is matched instead of the entire string.
  3. Only recognizes the deprecated :first-letter pseudo-class, not the ::first-letter pseudo-element.
  4. Only matches the very first character. The spec says that surrounding punctuation should also match.
