Umhlahlandlela olula wokusebenzisa izici ezikhethekile ku-HTML
Amakhasi wewebhu owavakashelayo ku-intanethi akhiwe ngokusebenzisa ikhodi ye-HTML etshela iziphequluli zewebhu ukuthi okuqukethwe kwekhasi kungakanani nokuthi ukuyibukisa kanjani ngokubukwa kwababukeli. Ikhodi iqukethe amabhulokhi wokwakha okubizwa ngokuthi izakhi, okuyinto umbukeli wekhasi lewebhu angaboni. Ikhodi nayo iqukethe izinhlamvu ezijwayelekile zombhalo ezinjengalezi ezihlokweni kanye nezigaba ezenzelwe umbukeli ukuba azifunde.
Indima Yezici Ezikhethekile E-HTML
Uma usebenzisa i-HTML bese uthayipha umbhalo owenzelwe ukubukwa, ngokuvamile awudingi amakhodi akhethekile-usebenzisa ikhibhodi yakho yekhompiyutha ukwengeza izinhlamvu ezifanele noma izinhlamvu. Inkinga ivela uma ufuna ukuthayipha uhlamvu kumbhalo ofundwayo u-HTML usebenzisa njengengxenye yekhodi ngokwalo. Lezi zinhlamvu zihlanganisa izinhlamvu ze <<> ezisetshenziselwa ikhodi ukuqala nokuqeda wonke amathegi we-HTML. Ungase futhi ufune ukufaka izinhlamvu kumbhalo ongenalo i-analog eqondile kwikhibhodi, njenge-© and Ñ. Kubalingiswa abangenayo ikhibhodi yakho, ufaka ikhodi.
Izinhlamvu ezikhethekile ziyizingxenye ezithile zekhodi ye-HTML eklanyelwe ukubonisa izinhlamvu ezisetshenziselwa ikhodi ye-HTML noma ukufaka izinhlamvu ezingatholakali kwikhibhodi embhalweni umbukeli obona. I-HTML ibuyisela lezi zinhlamvu ezikhethekile ngekhodi yezinombolo noma izinhlamvu ukuze zifakwe emgqulwini we-HTML, zifunwe yisiphequluli, futhi ziboniswe kahle izivakashi zendawo yakho ukuze zibone.
Izinhlamvu ezikhethekile ze-HTML
Izinhlamvu ezintathu ziyinhloko ye-syntax yekhodi ye-HTML. Akufanele neze uwasebenzise ezingxenyeni ezifundwayo zekhasi lakho lewebhu ngaphandle kokufaka ikhodi kuqala ekuboniseni okufanele. Ziyizinto ezinkulu kunazo zonke, ezingaphansi, nangama-ampersand. Ngamanye amazwi, akufanele nanini usebenzise uphawu olungaphansi kwe- < ikhodi yakho ye-HTML ngaphandle kokuthi kuqale ithegi ye- HTML. Uma wenza, umlingiswa udideka iziphequluli, futhi amakhasi akho angeke ahlinzeke njengoba ukulindele. Izinhlamvu ezintathu okufanele ungalokothi uzifake ezingavumelekile yizi:
- isibonakaliso esingaphansi <
- okukhulu-kunesibonakaliso >
- ampersand &
Uma uthayipha lezi zinhlamvu ngokuqondile kwi-HTML yakho-ngaphandle kokuthi ubasebenzisa njengamakheli ohlobo lwekhodi ekukhokheleni kwabo, ngakho-ke bavele kahle ematheksthini afundekayo:
- okungaphansi kwesibonakaliso - & lt;
- okukhulu-kunesibonakaliso - & gt;
- ampersand - & amp;
Uhlamvu ngalunye olukhethekile luqala nge-ampersand-ngisho nomlingisi okhethekile we-ampersand uqala nalo mlingisi. Izinhlamvu ezikhethekile ziphela nge-semicolon. Phakathi kwalezi zinhlamvu ezimbili, ufaka noma yikuphi okufanele umlingiswa okhethekile ofuna ukuyengeza. I-lt ( engaphansi kwe- ) yenza i-less-than symbol lapho ivela phakathi kwe-ampersand ne-semicolon ku-HTML. Ngokufanayo, i- gt ikhiqiza okukhulu-kunokuthi isignali futhi i- amp ikhulise i-ampersand uma ikhona phakathi kwe-ampersand ne-semicolon.
Izinhlamvu Ezikhethekile Awukwazi Ukuthayipha
Noma yiliphi uhlamvu olungahunyushwa ngesi-Latin-1 uhlamvu lomlinganiso olujwayelekile lungenziwa ngesi-HTML. Uma ingabonakali kwikhibhodi yakho, usebenzisa uphawu lwe-ampersand ngekhodi ehlukile eyabelwe uhlamvu olulandelwa yi-semicolon.
Isibonelo, i- "ikhodi enobungane" yephawu lokukopisha ikopisha ; kanye nokuhweba ; ikhodi yephawu lokuhweba.
Le khodi enobungane kulula ukuthayipha futhi kulula ukuyikhumbula, kodwa kunezinhlamvu eziningi ezingenayo ikhodi enobungane okulula ukuyikhumbula.
Njalo uhlamvu olungasetshenziswa ukuthayipha esikrinini lunamakhodi wezinombolo ezidumile. Ungasebenzisa le khodi yenombolo ukubonisa noma yiliphi uhlamvu. Isibonelo, ikhodi yenombolo yedasimali yesimboli se-copyright- & # 169; -demonstrates ukuthi amakhodi ezinombolo asebenza kanjani. Bese baqala nge-ampersand bese bephela nge-semicolon, kodwa esikhundleni sombhalo onobungane, usebenzisa isibonakaliso senombolo elandelwe ikhodi yenombolo ehlukile yalowo mlingiswa.
Amakhodi enobungane kulula ukuwakhumbula, kodwa amakhodi wezinombolo ngokuvamile athembekile kakhulu. Amasayithi akhelwe nge yolwazi kanye ne-XML kungenzeka ukuthi ayinakho wonke amakhodi enobungane achazwe, kodwa asekela amakhodi ezinombolo.
Indlela engcono kakhulu yokuthola amakhodi wezinombolo zezinhlamvu ziyizinhlamvu zamasethi ongayithola ku-intanethi. Uma uthola uphawu oludingayo, vele ukopishe futhi unamathisele ikhodi yenombolo ku-HTML yakho.
Ezinye izitayela zezinhlamvu zifaka:
- Amakhodi wemali
- Amakhodi wezibalo
- Amakhombandlela amakhodi
- Amakhodi wokumemezela
- Ama-diacritics amakhodi
Abalingiswa bolimi abangenzi isiNgisi
Izinhlamvu ezikhethekile azikhawulelwanga ulimi lwesiNgisi. Izinhlamvu ezikhethekile ngezilimi ezingezona isiNgisi zingaboniswa ku-HTML kubandakanya:
Ngakho Yimaphi Amakhodi We-Hexadecimal?
Ikhodi ye-hexadecimal yindlela ehlukile yokubonisa izinhlamvu ezikhethekile kwikhodi ye-HTML. Ungasebenzisa noma iyiphi indlela ofuna ngayo ikhasi lakho lewebhu. Ubabheka kubalingisi ubeka inthanethi futhi uwasebenzise ngendlela efanayo usebenzisa amakhodi enobungane noma amakhodi ezinombolo.

Amathiphu
Kungakhathaliseki ukuthi iyiphi indlela oyisebenzisayo, gcina ingqondo encane engqondweni:
- Gcina njalo into yakho nge-semicolon. Abanye abahleli be-HTML bakuvumela ukuthi uthumele amakhodi we-HTML ngaphandle kwe-semicolon yokugcina, kodwa amakhasi akho angeke avumelekile, futhi iziphequluli eziningi zewebhu ngeke zibonise izinhlangano ngendlela efanele ngaphandle kwalo.
- Qala njalo nge-ampersand. Abashicileli abaningi bewebhu bakuvumela ukuba ubalekele ngokushiya "amp;" kodwa uma ubonisa i-ampersand yedwa ku-XHTML, ibangela iphutha lokuqinisekisa.
- Hlola amakhasi akho kuziphequluli eziningi ngangokunokwenzeka. Uma uhlamvu lubalulekile ekuqondeni idokhumenti yakho futhi awukwazi ukuyihlola ekuhlanganisweni kwesiphequluli / OS amakhasimende akho asebenzisa, kufanele uthole enye indlela yokuyimela. Kodwa-ke, ngaphambi kokuba usebenzise izithombe noma enye into, zama enye yamathuluzi wokuhlola isiphequluli angaqinisekisa ikhodi yakho kuziphequluli eziningi.
