Yintoni i-HTML Tag kunye ne-HTML Element?

Kukho uhluko phakathi kwale mibini

Uyilo lweWebhu, njengawe nawuphi na umashishini okanye umsebenzi, unolwimi lonke. Njengoko ufaka i-shishini kwaye uqala ukuthetha noontanga bakho, ngokuqinisekileyo uya kuhamba ngokugqithiseleyo kwemigqaliselo kunye neengongoma ezitsha kuwe, kodwa ukuhamba kweelwimi zabasebenzi bakho bewebhu. Eminye yemiqathango oya kuyiva i-HTML "tag" kunye "nento".

Njengoko uva la magama mabini, ungabona ukuba zisetyenziselwa ukutshintsha. Ngaloo mbuzo, omnye umbuzo abaninzi abaqeqeshi bewebhu abaqalayo xa beqala ukusebenza ngekhowudi ye-HTML "yintoni umehluko phakathi kweTekisi ye HTML kunye ne-HTML Element?"

Nangona la magama mabini afana nengqiqo, ayenjalo ngokwenene. Ngoko yintoni na ukufana nale miqathango emibini? Impendulo emfutshane kukuba zombini ithegi kunye neenkalo zibhekisela kwisibhengezo esisetyenziswe ukubhala i-HTML. Ngokomzekelo, usenokuthi usebenzisa i-

ithethi ukuchaza umhlathi okanye isici ukudala iikhonkco. Abantu abaninzi basebenzisa iigatshana kunye neyinto kunye, kunye nawuphi na umyili wewebhu okanye umxhasi othetha naye uya kuqonda ukuba uthetha ntoni, kodwa inyaniso kukuba kukho umehluko ophakathi kwamagama amabini.

I-HTML yilwimi lokumakisha , oku kuthetha ukuba kubhaliwe ngeekhowudi ezinokufundwa ngumntu ngaphandle kokufuneka zihlanganiswe kuqala. Ngamanye amazwi, itekisi kwikhasi lewebhu "liphawulwe" ngala manqaku ukuze unikeze imiyalezo yesibhenkethi kwiindlela zokubonisa itekisi. Ezi tag tags ziyi-HTML tags ngokwabo.

Xa ubhala i-HTML, ubhala amathegi e-HTML. Zonke iithegi ze-HTML zenziwe ngamanani athile, kuquka:

• Umqondiso ongaphantsi <
• Igama okanye uphawu oluthetha ukuba yeyiphi ithegi ebhaliweyo
• Naliphi inani leempawu ze HTML ezikhethiweyo kwifomu yegama = "value" pair
• Kwaye ekugqibeleni mkhulu kunomqondiso>

Ngokomzekelo, nantsi i-HTML tags:

Lawa onke amathegi okuvula i-HTML, ngaphandle kweempawu ezikhethiweyo ezongeziweyo kubo. Ezi tags zimele:

• - ichaza umhlathi.

• - ichaza iphepha njenge HTML
• - ichaza ukwahlula.

Ezi zilandelayo zi-HTML tags:

• Le mizekelo yonke ifaka iimpawu eziye zongezwa kwiimpawu ze-HTML zokuvula.

  • U
    luluhlu olungenakucatshungulwa oluquka impawu ye-ID
    • Icandelo linomxholo weklasi
    • Ikhonkco, okanye isiqhagamshelo, into equka inqaku elithi "href"
    • Ithegi yomfanekiso nge-"src"

    Ukuze i-anchor kunye neetekisi zemifanekiso, iimpawu aziyikhethi, ziyimfuneko ukuba ezo tags zibonise ngokufanelekileyo. Kufuneka uxelele ikhonkco apho uya khona (yiyiphi "i-href" eyenzayo) kunye nomfanekiso oza kubonisa (yiyiphi impawu "i-src").

    Ziziphi i-HTML Elements

    Ngokubhekiselele kwi- W3C ye- HTML inkcazo, inqaku liyilo lokwakha i-HTML kwaye ngokuqhelekileyo lenziwe ngamathegi amabini : itekisi yokuvula kunye netekisi yokuvala. Kuze kube ngoku siye sajonga kuphela amathegi okuvula, eqala izinto. Ukuphelisa loo nto, ubhala ithegi zokuvala ezifanayo.

    Ngokomzekelo, isigaba somhlathi ubhala oku:

    Oku kuyenziwe itekisi yokuvula esiyibonayo umzuzwana odlulileyo kunye netekisi yokuvala - . Iimpawu zokuvala ziphela nje itekisi yokuvula ephindaphindiweyo, kodwa nge "slash phambili" yongezwe ngokuthe ngqo emva kwe "ngaphantsi kweyimboli".

    Phantse zonke izakhi ze-HTML zinomxholo wokuvula kunye netekisi lokuvala. Ezi zithegi zijikelezile umbhalo oza kubonisa kwikhasi lewebhu. Umzekelo, ukubhala umhlathi wesicatshulwa, ubhala itekisi ukuba ubonise kwiphepha uze uyijikeleze ngala manqaku:

    Yilapho ubhalela khona umhlathi womhlathi ongathanda ukuboniswa kwikhasi lewebhu.

    Ezinye izinto ze-HTML asinayo itektile yokuvala. Ezi zibizwa ngokuthi "izinto ezingenanto". Ngamanye amaxesha, kuthethwa ngokuba yi " singleton " okanye "izinto ezingenanto". Izinto ezingenalutho zilula ukuyisebenzisa kuba kufuneka ufake kuphela itekisi kwiphepha lakho lewebhu kwaye isiphequluli siyakwazi ukukwenza. Ngokomzekelo, ukufaka ikhefu elilodwa kwikhasi lakho oya kusebenzisa ib b
    tag.

    Elinye iqela eliqhelekileyo eliquka kuphela itekisi yokuvula ngumfanekiso "umfanekiso". Umzekelo:

    Sibone lo mzekelo kwangaphambili, kodwa akukho mfanekiso wokuvala walo mfanekiso wesithombe. Isikhangeli siza kufakazela le khowudi ngomfanekiso ochazwe kwi-"href". Kule meko, oko kuza kuba "logo.png".

    Ngokuqhelekileyo, xa ndibhekisela kwizinto ze-HTML okanye itekisi, ndiya kusebenzisa igama elithi "element" ukubonisa ukuba ndibhekisela kuzo zonke iindawo zento (zombini izithuba zokuvula nokuvala). Ndiyisebenzisa "ithegi" ngokwenene ndibhekisela enye kuphela okanye enye. Oku kusetyenziso olufanelekileyo kwezi zimbini, kwaye ndikukhuthaza ukuba uwasebenzise ngokufanelekileyo-kodwa uyazi ukuba ukuba uyayiphonsa kwaye uyitshintshisane nabo, uya kuqondwa ngoontanga lwakho olutsha lophuhliso lwewebhu!
