I su'esu'ega o lo'o lagolagoina ai le Itulau Visibility API , o le carousel o le a 'alofia le fa'ase'e pe a le va'aia e le tagata fa'aoga le itulau i luga ole laiga (pei o le taimi e le gaioi ai le itulau su'esu'e, fa'aitiitia le fa'amalama o le su'esu'ega, ma isi).

O le aafiaga o le animation o lenei vaega e fa'alagolago i le su'esu'ega a le prefers-reduced-motionaufaasālalau. Va'ai le vaega fa'aitiitiga fa'aitiitiga oa matou pepa fa'aoga avanoa .

Fa'amolemole ia nofouta e le'o lagolagoina fo'i ta'avale faga, ma e masani fo'i ona le ogatasi ma ta'iala fa'aoga.

I le mea mulimuli, afai o loʻo e fausiaina la matou JavaScript mai le puna, e manaʻomiautil.js .

Faataitaiga

A'o lagolagoina e carousels pulega ma fa'ailoga muamua/so'o mai, e le'o mana'omia manino. Fa'aopoopo ma fa'avasega pe a e mana'o e fetaui.

E .activemana'omia le fa'aopoopoina o le vasega i se tasi o fa'ata'ita'i a leai o le a le mafai ona iloa le ta'avale. Ia mautinoa foi e seti se tulaga tulaga ese idi luga o le .carouselmo le pule faitalia, aemaise lava pe afai o loʻo e faʻaaogaina le tele o carousels i luga o le itulau e tasi.
