Carousel

Komponen slideshow kanggo muter liwat unsur-gambar utawa slide teks-kaya carousel.

Cara kerjane

Carousel minangka slideshow kanggo muter liwat seri konten, dibangun nganggo transformasi CSS 3D lan sawetara JavaScript. Kerjane karo seri gambar, teks, utawa markup khusus. Uga kalebu dhukungan kanggo kontrol lan indikator sadurunge / sabanjure.

Ing browser ing ngendi API Visibilitas Kaca didhukung, carousel ora bakal geser nalika kaca web ora katon kanggo pangguna (kayata nalika tab browser ora aktif, jendhela browser diminimalisir, lsp.).

Elinga yen carousel bersarang ora didhukung, lan carousel umume ora tundhuk karo standar aksesibilitas.

Pungkasan, yen sampeyan nggawe JavaScript saka sumber, mbutuhakeutil.js .

Tuladha

Uga manawa kanggo nyetel id unik ing .carouselkanggo kontrol opsional, utamané yen sampeyan nggunakake macem-macem carousel ing kaca siji. Unsur kontrol lan indikator kudu nduweni data-targetatribut (utawa hrefkanggo pranala) sing cocog karo id .carouselunsur kasebut.
