Xiphemu xa nkombiso wa swilayidi xo rhendzeleka hi swiaki—swifaniso kumbe swilayidi swa tsalwa—ku fana ni carousel.

Eka tluka leri

Ndlela leyi swi tirhaka ha yona

Carousel i nkombiso wa swilayidi wo rhendzeleka hi ku tirhisa nxaxamelo wa swilo leswi nga endzeni, lowu akiweke hi ku hundzuka ka CSS 3D na xiphemu xa JavaScript. Yi tirha hi nxaxamelo wa swifaniso, tsalwa kumbe ku fungha loku endleriweke wena. Yi tlhela yi katsa nseketelo wa vulawuri bya khale/leswi landzelaka na swikombiso.

Eka swihlamusela-marito laha API ya ku Vonakala ka Tluka yi seketeriwaka, carousel yi ta papalata ku rhetela loko tluka ra webu ri nga vonaki eka mutirhisi (ku fana na loko thebhu ya xihlamusela-marito yi nga tirhi, fasitere ra xihlamusela-marito ri hungutiwile, na swin’wana).

Vuyelo bya animation bya xiphemu lexi byi titshege hi prefers-reduced-motionxivutiso xa midiya. Vona xiyenge xa ​​ku famba loku hungutiweke xa matsalwa ya hina ya ku fikelela .

Hi kombela u tiva leswaku ti carousels leti nga na swisaka a ti seketeriwi, naswona ti carousels hi ntolovelo a ti fambisani na swipimelo swa ku fikelela.

Xikombiso

Ti carousels a ti tiendli ti normalize ti slide dimensions. Hi ndlela yoleyo, u nga ha lava ku tirhisa switirhisiwa leswi engetelekeke kumbe switayele swa ntolovelo leswaku u pima swilo leswi nga endzeni hi ndlela leyi faneleke. Loko ti carousels ti seketela vulawuri bya khale/lebyi landzelaka na swikombiso, a swi laveki hi ku kongoma. Engetelani u tlhela u endla hi ku landza swilaveko swa wena hilaha u vonaka swi fanerile hakona.

Tlilasi .activeyi lava ku engeteriwa eka yin’wana ya tislaydi handle ka sweswo carousel a yi nge vonaki. Nakambe tiyiseka leswaku u veka yo hlawuleka ideka ya .carouselvulawuri byo hlawula, ngopfu-ngopfu loko u tirhisa ti- carousel to tala eka tluka rin’we. Swiaki swa vulawuri na xikombiso swi fanele ku va na data-bs-targetxihlawulekisi (kumbe hrefxa swihlanganisi) lexi fambelanaka na idxa .carouselxiaki.
