Jak tworzyć przezroczyste zdjęcia?

Możliwe jest nadanie przechwytywanym obrazom HTML i zrzutom ekranu adresów URL przezroczystego tła. Jednak zadziała to tylko wtedy, gdy tło przechwytywanego kodu HTML jest przezroczyste, a format obrazu to PNG lub TIFF. Jeśli użyjesz formatu obrazu innego niż PNG lub TIFF, otrzymasz czarne tło.

Aby dokument HTML miał przezroczyste tło, właściwość tła CSS musi być ustawiona na przezroczystość zarówno dla html i body tagi, jak pokazano w poniższych przykładach.
