I-version yokuqala ye-HTML ayinayo inombolo yenguqulo, ibizwa nje ngokuthi "i-HTML" futhi isetshenziselwa ukubeka amakhasi eWebhu alula emuva ngo-1989 kuya ku-1995. Ngo-1995, i-IETF (i-Internet Engineering Task Force) i-HTML ehlelekile futhi ibalwa it "HTML 2.0".
Ngo-1997, iWorld Wide Web Consortium (W3C) inikeze inguqulo elandelayo ye-HTML, i-HTML 3.2. Lalandelwa i-HTML 4.0 ngo-1998 no-4.01 ngo-1999.
Khona-ke i-W3C yamemezela ukuthi ngeke idale izinguqulo ezintsha ze-HTML, futhi izoqala ukugxila kwi-HTML eyengeziwe noma i-XHTML. Bancoma ukuthi abaklami bewebhu basebenzise i-HTML 4.01 yemiqulu yabo ye-HTML.
Ngalesi sikhathi, ukuthuthukiswa kwahlukaniswa. I-W3C igxile ku-XHTML 1.0, futhi izinto ezifana ne-XHTML Basic zaba izincomo ngo-2000 nangaphezulu. Kodwa abaklami bewebhu abafuni ukuthuthela kwesakhiwo esiqinile se-XHTML, ngakho ngo-2004, i-Web Hypertext Application Technology Group Group (WHATWG) yaqala ukusebenza ku-version entsha ye-HTML engeyona eqinile njengoba i-XHTML ibiza i-HTML5. Bathemba ukuthi lokhu kuzokwamukelwa njengencomo ye-W3C.
Inquma ngenguqulo ye-HTML
Isinqumo sakho sokuqala uma ubhala ikhasi lewebhu kungukuthi ubhale ku-HTML noma ku-XHTML. Uma usebenzisa umhleli njengoDreamweaver, lokhu kukhetha kunqunywa yi-DOCTYPE oyikhethayo. Uma ukhetha i-DOHYPE ye-XHTML, ikhasi lakho lizobhalwa ku-XHTML futhi uma ukhetha i-DOCTYPE ye-HTML, uzobhala ikhasi nge-HTML.
Kukhona inani lokungafani phakathi kwe-XHTML ne-HTML. Kodwa okwamanje, konke okudingeka ukwazi ukuthi i-XHTML i-HTML 4.01 iphinde ibhalwe njengesicelo se-XML. Uma ubhala i-XHTML, zonke izimfanelo zakho zizocatshangwa, amathegi wakho avaliwe, futhi ungayilungisa kumhleli we-XML. I-HTML ingcono kakhulu kune-XHTML ngoba ungashiya izingcaphuno ezikhishwe izimfanelo, shiya amathegi afana
ngaphandle komaki wokuvala
njalo njalo.
Kungani usebenzisa i-HTML
- I-HTML ingathatha isikhala esingaphansi, ngakho-ke yiba namandla okulanda.
- I-HTML inokuthethelela futhi kulula ukufunda. Isibonelo, uma ushiya amathegi ku-HTML, ikhodi yakho izoqhubeka isebenza ngokuthembekile.
- Ezinye iziphequluli ezindala ziphendula ngokuphumelelayo ku-HTML kune-XHTML.
Kungani Kufanele Usebenzise i-XHTML
- I-XHTML icacile ekuqaliseni nasekugcineni kwamathegi - izitayela nezenzakalo ezinjalo zingabanjwa kalula.
- I-XHTML ihlanganisa kahle kwezinye izilimi zokuhlela ngoba i-XML.
- Ezinye iziphequluli ziphendula ngokuthe xaxa ku-XHTML ngakho-ke zibonise amakhasi ngokuqhubekayo, ngisho naphakathi kwamapulatifomu.
Uma Uke Wakhetha Ku-HTML noma i-XHTML - Yimaphi Inguqulo Okufanele Uwasebenzise?
HTML
Kukhona izinguqulo ezintathu ze-HTML ezisetshenziswa ngokujwayelekile emhlabeni jikelele:
- I-HTML 3.2
- I-HTML 4.0
- I-HTML 4.01
Futhi abanye bangase bathi inguqulo yesine inguqulo ye "no-DOCTYPE". Lokhu kuvame ukubizwa ngokuthi imodi ye-quirks futhi ibhekisela kumadokhumenti e-HTML angenayo i-DOCTYPE ecacisiwe bese iphela ngokubonisa ngokuzenzakalelayo kuziphequluli ezahlukene.
Ngincoma i-HTML 4.01. Lena inguqulo yakamuva kakhulu yezinga elijwayelekile, futhi yiyona evunyelwe kakhulu yiziphequluli zanamuhla. Kufanele usebenzise kuphela i-HTML 4.0 noma i-3.2 uma unesizathu esithile (njengokuthi ukwakha i-Intranet noma i-kiosk lapho izibukeli ezibukelayo zixhasa kuphela amathegi angu-3.2 noma angu-4.0 nezinketho). Uma ungazi ukuthi uleso simo, awukho, futhi kufanele usebenzise i-HTML 4.01.
XHTML
Kukhona okwamanje izinguqulo ezimbili ze-XHTML: 1.0 no-2.0.
I-XHTML 2.0 intsha kakhulu kodwa ayisekelwa yiziphequluli zewebhu. Ngakho- ke ngincoma ukusebenzisa i-XHTML 1.0 okwamanje. Kuyoba mnandi ngempela uma i-XHTML 2.0 isekelwa kabanzi, kodwa kuze kube yileso sikhathi, sidinga ukunamathela ngezinguqulo abafundi bethu abangasebenzisa.
Uma Uke Wakhetha Ku-Version
Qinisekisa ukusebenzisa i-DOCTYPE. Ukusebenzisa i-DOCTYPE kungumzila owodwa kuphela kumadokhumenti akho e-HTML, futhi kuqinisekisa ukuthi amakhasi akho aboniswa ngendlela abahloselwe ukuboniswa ngayo.
I-DOCTYPE yezinguqulo ezihlukahlukene yilezi:
HTML
- I-HTML 4.01 yesikhashana:
- I-HTML 4.01 eqinile:
- I-HTML 4.01 ifakiwe:
- I-HTML 3.2:
XHTML
- I-XHTML 1.0 yesikhashana:
- I-XHTML 1.0 eqinile:
- I-XHTML 1.0 i-Frameset:
- I-XHTML 2.0:
