Saya melihat denyar itu sangat mudah untuk melaksanakan animasi seperti ini, jadi saya cuba mengacaukannya. Semuanya adalah piksel yang disimulasikan menggunakan DOM dan pengalianan tidak dapat dielakkan...
Untuk mengelakkan alias, saya mungkin perlu menambah penapis lain atau menggunakan gambar.

Jika anda berminat, anda boleh membincangkannya.
Selain itu, saya juga menghadapi masalah Penapis ketelusan di bawah iaitu dalam kod di atas tidak berfungsi Selepas penyelidikan, didapati menukar kedudukan bekas induk akan menjejaskan pewarisan penapis ketelusan anak. nod.
Di atas adalah keseluruhan kandungan artikel ini, saya harap anda semua menyukainya.
