Ngesikhathi sika klama ikhasi lewebhu, kubalulekile ukwazi ezinye izindlela ezihlukene kanye namathuluzi atholakalayo okuzulazula okunembile nokuwuketshezi. Elinye lalawa mathuluzi yisilayidi esiguqukayo futhi ukufunda indlela yokusidala kulula futhi kuwusizo kakhulu ukubonisa ulwazi ngendlela ekhangayo nehlelekile.
Izilayidi Ezinamandla zengeza ukusebenzisana kuwebhusayithi, okuvumela umsebenzisi ukuthi ahlole izingcezu ezahlukene zokuqukethwe nemifanekiso ngendlela enembile futhi esindisa isikhathi. Angadalwa ngezindlela ezahlukene kuye ngolimi olusetshenziswayo, ukusuka ku-JavaScript kuye ku-CSS noma ku-HTML. Ukuze ufunde ukuthi ungakha kanjani isilayidi esiguqukayo, izibonelo ezimbalwa nje ezisebenzayo zanele futhi ungahlanganisa nobuchwepheshe obuthathu bokuklama iwebhu futhi uthole izinketho ezisebenzayo nezikhangayo kakhulu.
Sinjani isakhiwo se-HTML lapho udala isilayidi esiguqukayo?
Noma yisiphi isilayidi esiguqukayo ozosenza kuqala sinesakhiwo se-HTML esiqinile nesihleleke kahle, ngaphandle kwalokho umphumela ungaba yinhlekelele. Isakhiwo sikuvumela ukuthi uhlalise kalula futhi ubonise ukuze izithombe eziyingxenye yewebhusayithi yethu.
I-HTML yesilayidi esiguqukayo kufanele ilunge ngokwezibalo futhi sibe nesakhiwo esenza kube lula ukufinyeleleka. Ungasebenzisa amathegi e-HTML5 ukuze uhlale ugcine kokubili ukwakheka nesemantics yekhodi kucacile.
Ngomaka we-SECTION ungakwazi ukuhlanganisa isilayidi ukuze usinikeze ukubamba. Sebenzisa i-div ye-gallery-container ukuze ubeke zonke izici ezizoba kusilayidi, bese usonga isithombe ngasinye nge-FIGURE kanye nomaka we-FIGCAPTION ongayikhetha ukuze ufake incazelo. Izilayidi eziningi zisebenzisa umaka we-NAV ukuze zifake izinkinobho futhi ngaleyo ndlela zinikeze izinketho zokusebenzisana komsebenzisi.
Dala isilayidi esiguqukayo nge-CSS
Ukunikeza isilayidi sakho esiguqukayo a isitayela esicophelelayo nesinemininingwane, ungasebenzisa i-CSS (AmaSpredishithi esitayela seCascading). Ngokusebenzisa izinketho zayo ungachaza ukwakheka, iphalethi yombala, imiphumela yoshintsho nezinye izinketho zobuhle kanye nokusebenza kwesilayidi. Ukhiye lapho usebenzisa i-CSS ukwazi ububanzi nemikhawulo yayo, uhlale ucabanga ngezigaba zobuhle nezesitayela zesilayidi okukhulunywa ngaso.
- Uzokwazi ukuchaza ububanzi nemajini yesigaba sesilayidi ekhasini lakho. Inketho enhle ukuyibeka phakathi nendawo ukuze ugweme ukuchichima noma yisiphi isithombe.
- Nge-DISPLAY ne-FLEX esigabeni sesiqukathi segalari ungakwazi ukuhlela izinto zilandelana. Ngesici se-TRANSITION, umphumela oshelelayo usetshenziswa lapho usuka esithombeni usiya kwesinye. Ngokusebenzisa i-TRANSFORM ungashintsha izici zalolu shintsho, ulwenze lusheshe, luhambe kancane noma lube nemiphumela.
- Khetha ububanzi obuncane obungu-MIN-WIDTH, usayizi webhokisi wesilayidi BOX-SIZING kanye neBORDER-BOX futhi ngale ndlela uzosithola ngokugcwele isikhala, ngaphandle kwezimanga.
- Izinketho ze-DISPLAY, FLEX kanye ne-JUSTIFY CONTENT, ISIKHALA-PHAKATHI zikhetha indawo yezinkinobho ezisebenzisanayo. Ungawabeka ezindaweni ezibhekene ukuze umsebenzisi akwazi ukusuka kolunye uhlangothi aye kolunye ngendlela enembile kugalari.
Izici zokusebenzisana ne-JavaScript
Ubuchwepheshe besithathu okufanele wazi kubo klama isilayidi esiguqukayo I-JavaScript. Kulokhu ibhekana nezigaba ezihlobene nokusebenzelana okuvela esibonakalayo sewebhu. Ungasebenzisa i-Java ukwenza isilayidi sibe nobungane kakhulu futhi sihlanganyele, wengeze imisebenzi ezolungiswa ngokuqondile ngokungenelela komsebenzisi.
- Ezinye izibonelo ezisebenzayo zezilayidi ezine-JavaScript zifaka phakathi okuguquguqukayo kwe-currentIndex. Lokhu kugcina umkhondo wesithombe samanje esivezwe kusilayida.
- Nge-EVENT LISTENERS ungakwazi ukwenza kusebenze umsebenzi we-NAVIGATE ngesiqondiso -1 (esidlule) noma 1 (olandelayo) futhi usuke esithombeni esisodwa uye kwesinye ngokuvumelana nezithakazelo zakho.
- Umsebenzi we-NAVIGATE futhi ikuvumela ukubala ukususwa okudingekayo kusuka esithombeni esisodwa kuya kwesinye (OFFSET) futhi ngaleyo ndlela ubonise isithombe osifunayo lapho ucindezela inkinobho.
- Nge-TRANSFORM, TRANSLATEX ungakwazi ukuqedela ukumisa isilayidi ukuze kuthi lapho sithuthela endaweni ekhonjiwe, sibonise isithombe okukhulunywa ngaso.
I-Las Imigqa yeJavaScript Angasetshenziswa ukwengeza ukusebenza okuyisisekelo ekuzulazuleni kwesilayidi. Umsebenzisi uzokwazi ukuhambisa phakathi kwamafayela ahlukene aqukethwe kugalari okukhulunywa ngayo ngendlela enembile nelula.
Umsebenzi wokuzidlalela ku-dynamic slider
Kukhona ezinye izilayidi ezinamandla ebonisa ngokuzenzakalelayo nangokuzungeza izithombe ngaphakathi kwegalari. Lezi zilayidi zinomsebenzi wokuzidlalela ngokuzenzakalela osebenzayo. Ukuzidlalela kupheqa izithombe ngokuzenzakalelayo ngezikhathi ezithile. Ukusebenza kungengezwa kalula ngokusebenzisa ulimi lwe-JavaScript.
- Kukhona okuhlukile okuhlukile okufanele kucatshangelwe ukuze ukudlala ngokuzenzakalela kusebenze. Okokuqala, inketho ye-AUTOPLAYINTERVAL. Ichaza isihlonzi sesikhathi soshintsho oluzenzakalelayo.
- I-STARTAUTOPLAY ithatha isikhawu sesikhathi njengesithenjwa (sibalwe ngama-millisecond). Imisa noma yikuphi ukudlala ngokuzenzakalela kwangaphambilini ukuze ingakhi ukungahambisani, futhi iqala isikhawu esisha ukuze ushayele umsebenzi we-NAVIGATE futhi uzulazule.
- Nge-STOPAUTOPLAY ungamisa ukuzidlalela. Ungayisebenzisela ukumisa ukuzulazula okuzenzakalelayo uma umsebenzisi esebenzisana nesilayidi.
- I-AUTOPLAY ivamise ukumiswa lapho umsebenzisi esebenzisana nezinkinobho zokuzulazula ezenziwa mathupha.
Ukusetshenziswa kwesilayidi esiguqukayo
Amakhasi ewebhu asebenzisa i- izilayidi ezinamandla ukukhiqiza ukuzulazula okubonakalayo nokukhangayo okuningi phakathi kwama-elementi e-multimedia. Ngokuvamile zisetshenziselwa kokubili izithombe ezimile namavidiyo. Ungazilungiselela ngezici ezihlukene nezinkinobho zesenzo ngokusebenzisa izilimi eziyinhloko, i-CSS, i-HTML ne-JavaScript.
Lapho uklama iwebhusayithi yakho futhi hlanganisa izilayidi eziguqukayo, kubalulekile ukwazi nokuguqula okuguquguqukayo ngokuhambisana. Uma kungenjalo, ungagcina udala izinkinga zokubonisa noma zokuzulazula ngenxa yamaphutha e-syntax.
Inqubo ifundwa, okokuqala ngethiyori kanye nolwazi lwezindlela ezihlukile ezitholakalayo. Futhi okwesibili ngokusetshenziswa okungokoqobo kwamathuluzi ahlukene ukuqedela ukuhlola imiphumela yawo. Kuwumkhuba othokozisayo ukuthi umklami wewebhu afunde ukwazi ubuchwepheshe obuhlukahlukene, ububanzi bazo kanye nemikhawulo ukuze ube nalezi zinto kuwebhusayithi yakho ngendlela enembile nephumelelayo. Ngaphandle kwezinkinga futhi ngaso sonke isikhathi.
