Saya membuat percubaan kecil untuk menggunakan penyeretan tetikus dengan CSS3 Tangkapan skrin adalah seperti berikut:
Rakan-rakan yang biasa dengan kesan seretan harus biasa dengan kaedah seret ke kiri dan kanan selepas menahan tetikus.
Apa yang cuba demo kecil ini ialah menggunakan mata pengetahuan yang berkaitan dalam CSS3 pada paparan imej,
Apabila menyeret gambar, ia akan menunjukkan perasaan tiga dimensi~~
Kod langsung adalah seperti berikut:
