Carousel

He kiʻi kiʻiʻoniʻoni no ka holo kaʻa ʻana ma waena o nā mea—nā kiʻi a i ʻole nā ​​kiʻi paheʻe o ke kikokikona—e like me ka carousel.

Ma kēia ʻaoʻao

Pehea e hana ai

ʻO ka carousel kahi kiʻi kiʻiʻoniʻoni no ka holo kaʻa ʻana ma waena o nā ʻike, i kūkulu ʻia me CSS 3D transforms a me kahi hapa o JavaScript. Hoʻohana ia me nā kiʻi, kikokikona, a i ʻole markup maʻamau. Loaʻa pū kekahi i ke kākoʻo no nā mana mua / aʻe a me nā hōʻailona.

Ma nā polokalamu kele pūnaewele kahi i kākoʻo ʻia ai ka API Visibility ʻAoʻao , e pale ka carousel i ka paheʻe ʻana ke ʻike ʻole ʻia ka ʻaoʻao pūnaewele e ka mea hoʻohana (e like me ke ʻano ʻole o ka ʻaoʻao pūnaewele, hoʻemi ʻia ka puka aniani, a pēlā aku).

ʻO ka hopena animation o kēia māhele e pili ana i ka prefers-reduced-motionnīnau media. E ʻike i ka ʻāpana hoʻohaʻahaʻa o kā mākou palapala hiki ke komo .

E ʻoluʻolu e ʻoluʻolu ʻaʻole kākoʻo ʻia nā carousels pūnana, a ʻaʻole kūlike nā carousels i nā kūlana hiki ke loaʻa.

Laʻana

ʻAʻole hana maʻamau nā Carousels i nā ana paheʻe. No laila, pono paha ʻoe e hoʻohana i nā pono hana hou a i ʻole nā ​​​​ʻano maʻamau i ka nui o ka ʻike. ʻOiai ke kākoʻo nei nā carousels i nā mana a me nā hōʻailona o mua/hope aku, ʻaʻole koi ʻia lākou. Hoʻohui a hoʻopilikino e like me kou manaʻo he kūpono.

Pono .activee hoʻohui ʻia ka papa i kekahi o nā paheʻe i ʻole e ʻike ʻia ka carousel. E ʻoluʻolu hoʻi e hoʻonoho i kahi ʻokoʻa idno .carouselnā mana koho, ʻoi aku paha inā ʻoe e hoʻohana ana i nā carousels he nui ma ka ʻaoʻao hoʻokahi.
