Wykonajmy następujące kroki, aby zobaczyć, jak działa powyższy kod -
Zapisz powyższy kod HTML jako accordion.html plik w folderze głównym serwera.
Otwórz ten plik HTML jako http: //localhost/accordion.html, a dane wyjściowe zostaną wyświetlone, jak pokazano poniżej.
W przykładzie przedstawiono zwijany układ, który można rozwinąć, aby wyświetlić zawartość skojarzoną z harmonijką.
