I-version yokuqala ye-HTML ayinayo inombolo yenguqu, yabizwa ngokuba yi "HTML" kwaye isetyenziselwa ukubeka amaphepha eWebhu alula kwakhona ngo-1989 ukuya ku-1995. Ngo-1995, i-IETF (i-Intanethi yobunjineli be-Task Force) i-HTML imiselwe kwaye ibalwa "HTML 2.0".
Ngomnyaka we-1997, iWorld Wide Web Consortium (W3C) inikezele inguqulo elandelayo ye HTML, HTML 3.2. Yalandelwa yi-HTML 4.0 ngo-1998 kunye ne-4.01 ngo-1999.
Emva koko iW3C yazisa ukuba ayiyi kudala iinguqulelo ezintsha ze-HTML, kwaye iza kuqala ukugxila kwi-HTML ecacileyo okanye i-XHTML. Bancoma abayili bewebhu bebenzisa i-HTML 4.01 kumaphepha abo e-HTML.
Kuloo ndawo, uphuhliso luhlukaniswe. I-W3C ijolise kwi-XHTML 1.0, kwaye izinto ezifana ne-XHTML Basic zaba iingcebiso ngo-2000 nangaphezulu. Kodwa abayili bewebhu abafuni ukufudukela kwisakhiwo esiqinileyo se-XHTML, ngoko ngo-2004, i-Web Hypertext Application Technology Group (I-WHATWG) yaqalisa ukusebenza kwinguqulelo entsha ye-HTML engagqithisi njenge XHTML ebizwa nge-HTML5. Bathemba ukuba oku kuza kugqitywa njenge-W3C.
Ukugqiba kwi-Version ye HTML
Isinqumo sakho sokuqala xa ubhala iphepha leWebhu kukuthi ubhale kwi HTML okanye XHTML. Ukuba usebenzisa umhleli njengoDreamweaver, olu khetho lugqitywe yi-DOCTYPE oyikhethayo. Ukuba ukhetha i-DOCTYPE ye-XHTML, iphepha lakho liya kubhalwa kwi-XHTML kwaye ukuba ukhetha i-DOCTYPE ye-HTML, uya kubhala iphepha kwi-HTML.
Kukho inani lokungafani phakathi kwe-XHTML kunye ne-HTML. Kodwa ngoku, konke okufuneka ukwazi ukuba i-XHTML yi-HTML 4.01 ebhalwe kwakhona njenge-XML. Ukuba ubhala i-XHTML, zonke iimpawu zakho ziza kucatshulwa, amathegi akho avaliwe, kwaye ungayihlela kumhleli we-XML. I-HTML yinto elula kakhulu kune XHTML kuba unokushiya amacaphuno kwiimpawu, shiya amathegi afana
ngaphandle kwetawu yokuvala
kwaye nangokunjalo.
Kutheni usebenzise i-HTML
- I-HTML inokuthatha indawo encinane, kwaye ke mkhulu ukukhuphela.
- I-HTML ixolela ngakumbi kwaye kulula ukufunda. Umzekelo, ukuba ushiya amathegi kwi-HTML, ikhowudi yakho iya kusebenza ngokuthembeka.
- Ezinye iziphequluli ezidala ziphendula ngokuthe ngempumelelo kwi-HTML kuneXHTML.
Kutheni usebenzise i-XHTML
- I-XHTML icacile ekuqalekeni nasekupheleni kweeteks - ngoko izitayela kunye neziganeko zingabanjwa ngokulula.
- I-XHTML idibanisa kwezinye iilwimi zokufunda kuba yiXML.
- Ezinye iiphequluli ziphendula ngokuthe tye kwi XHTML kwaye ngoko zibonisa amaphepha rhoqo, nakwii-platform.
Emva kokuba Wena & # 39; Ukhethile kwi-HTML okanye XHTML - Yiyiphi inguqulo ofuna ukuyisebenzisa?
HTML
Kukho iinguqu ezintathu ze-HTML zisetyenziswa ngokuqhelekileyo kwi-intanethi:
- HTML 3.2
- HTML 4.0
- HTML 4.01
Kwaye abanye banokuthi ingqungquthela yesine yinguqulo "akukho-DOCTYPE". Oku kudla ngokuba yi- quirks mode kwaye ibhekisela kumaxwebhu e-HTML angenayo i-DOCTYPE ecacileyo kwaye ngokugqibeleni ibonisa ngokuqinisekileyo kwiziphequluli ezahlukeneyo.
Ndincoma i-HTML 4.01. Le yenguqu yentsholongwane yamuva, kwaye iyona yamkeleke kakhulu kwiiphequluli zanamhlanje. Umele usebenzise i-HTML 4.0 okanye 3.2 ukuba unesizathu esithile (njengokuba ukwakhiwa kwe-Intranet okanye i-kiosk apho izikhangeli ezibukelayo zixhasa kuphela i-3.2 okanye 4.0 itekethi kunye neenketho). Ukuba awukwazi ukuba ungoko, kwaye awukho, kwaye kufuneka usebenzise i-HTML 4.01.
XHTML
Kukho iinguqulelo ezimbini ze-XHTML: 1.0 ne-2.0.
I-XHTML 2.0 intsha kwaye ayinakunikwa inkxaso yi-Web browsers. Ngoko ndincoma ukusebenzisa i-XHTML 1.0 ngoku. Kuya kuba kuhle xa i-XHTML 2.0 ixhaswa ngokubanzi, kodwa kude kube ngoko, kufuneka sibambelele ngeenguqu ezifundwa ngabafundi bethu.
Emva kokuba u & # 39; Ukhethile kwi-Version
Qinisekisa ukusebenzisa i-DOCTYPE. Ukusebenzisa i-DOCTYPE yile mgca omnye kumaphepha akho e-HTML, kwaye iyaqinisekisa ukuba amaphepha akho aboniswa ngendlela ejoliswe ngayo ukuba iboniswe.
I-DOCTYPE zeenguqu ezahlukeneyo zi:
HTML
- HTML 4.01 yenguqu:
- HTML 4.01 eqinile:
- HTML 4.01 ifowuni:
- HTML 3.2:
XHTML
- XHTML 1.0 yenguqu:
- XHTML 1.0 eqinile:
- XHTML 1.0 iFameset:
- XHTML 2.0:
