Coding html. Njengoba obudaywe ikhasi lewebhu

Njengoba indlela ka ikhodi Imininingwane yokudlulisela yayo phezu Inthanethi usebenzisa i-html esephepheni. Icacisa ipharamitha ngesikhathi le nqubo actuated, inani izingcezu idluliselwa kubo nge uphawu oluthile. Ngakho omunye kancane buqonda pair of amagugu, izingcezu ezimbili enzelwe ngamakhodi amagugu ezine, emithathu ibhithi - eziyisishiyagalombili. Ukungeza izingcezu, ungakwazi kabili inombolo yamanani okubhalwe. Ngakho, 8 izingcezu kungaba encode ukulandelanisa 256 (amagugu) e -binary code. Isici esiphawulekayo ukuthi ukulandelana ngasinye iyagcinwa amandla okudlulisela uhlamvu umbhalo. Kuvele wekhodi okunye izingcezu eziyisishiyagalombili iyona esephepheni at 16 no-32-bit, banayo amandla nokucubungula 65.536, ngokulandelana, 4294967296 umbhalo izinhlamvu.

Ukuvula isiphequluli kuhlanganisiwe Windows Internet Explorer, ungakwazi kwimenyu "Buka - Ukufaka ikhodi 'ukuze ubone uhlu olude lokubhala ngobumfihlo ezahlukene.

Coding html kungaba kahle ukubonisa ulwazi ekhasini lewebhu. Ngenxa protocol ekhona kushintshwa phakathi iseva kanye ulwazi isiphequluli sewebhu inkonzo anokwaziswa oluphelele indlela esetshenziselwa wekhodi yombhalo.

Ukusebenzisa umthetho olandelwayo we-HTTP, wenziwa inqubo ukuthumela isiphequluli sewebhu iseva imiyalezo, okuyinto wathola, iseva uthatha ikhasi oyifunayo bese ilihumusha (recode) ngohlobo oludingekayo. In the ukungabikho idokhumenti ku iseva (ekhasini le-Web), kubalulekile ukukhetha ezifanele esephepheni ngokwakho (ngesandla).

Coding html ikuvumela wasibekela kwemigomo elandiwe khasi lewebhu. Phela, embonweni efanele incike yomsebenzisi isiphequluli zibalwa isisetshenziswa sewebhu. Ngokwesibonelo, ngisho imibala wasebenzisa ekhasini ebizwa ngokuthi ikhodi.

Coding html imibala kwenzeka ngokuchaza umbala oyifunayo e gradations imibala eyinhloko. Ukuze uthole umbala wayefisa qapha exutshwa olinganise wayefisa imibala eyinhloko - abomvu (Red), green (Green), futhi okwesibhakabhaka (Blue). Ngakho, entry ikhodi RGB ngoba umbala okumsulwa obomvu libukeka rgb (255,0,0). isethi yezinombolo kubakaki ngoba umbala oluhlaza izokwethulwa lakhetsiwe 0,255,0, for the blue - 0,0,255. Classically umbala ophuzi code inhlanganisela 255,255,0 mpungana oluhambisana ikhodi 255,0,255. Ngo black chislosochetanie kubukeka sengathi 0,0,0, white 255.255.255 futhi 192.192.192 grey.

Ukumeleleka ngenhla umbala kunikezwa ukuzwakala, html esephepheni ukusebenzisa notation-hexadecimal (HEX) oqala #. Uma ubhala ikhodi HEX nombala omnyama umelwe # 000000, White - #FFFFFF, ompunga - C0C0C0 #. Ngamakhodi imibala eyinhloko obomvu, oluhlaza okwesibhakabhaka izobukeka # ff0000, # 00FF00, # 0000ff, ngokulandelana.

I-W3C isebenzisa 16 imibala, i-HTML evumelekile futhi CSS.

Ukuze imibala akufakiwe kulolu hlu, ukuthi ilungile ngaphezulu ukusebenzisa HEX noma RGB ikhodi.

welithi "imibala ephephile" kwakuvamile eminyakeni embalwa edlule, okulinganisela ezahlukene imibala elisetshenziswa ukudalwa amakhasi ewebhu, lewebhu 216 imibala. Ukuthuthukiswa computer uzisusile yonke imikhawulo kule ndaba.
