Kod kesan menu lungsur sudut bulat klasik yang dilaksanakan oleh kemahiran JS CSS_javascript
Contoh dalam artikel ini menerangkan kod kesan menu lungsur turun sudut bulat yang dilaksanakan oleh JS CSS. Kongsikan dengan semua orang untuk rujukan anda, butirannya adalah seperti berikut:
Saya percaya ramai rakan akan menyukai menu ini Menu lungsur turun yang dibulatkan oleh CSS JS tidak menggunakan sebarang imej hiasan Sudut bulat lengkap dengan JS, jadi terdapat sedikit lagi kod gunakannya Rakan saya mengekstrak fail JS dan menyimpannya secara berasingan, yang lebih munasabah.
Tangkapan skrin kesan berjalan adalah seperti berikut:
