Cov kev coj ua zoo tshaj plaws rau kev sau HTML 5 ntsiab lus
Ib lo lus nug hais tias ntau lub vas sab tshiab cov neeg tsim muaj qhov tsis yog HTML 5 cim npe yog muaj case sensitive? Cov lus teb luv yog - "Tsis yog". HTML5 cim npe tsis yog case sensitive, tab sis qhov tsis txhais hais tias koj yuav tsum tsis nruj rau li cas koj sau koj cov HTML cim npe!
Rov qab mus rau XHTML
Ua ntej HTML5 tuaj rau hauv txoj kev ua lag luam , cov kws ua hauj lwm hauv web yuav siv cov lus nplaum hu ua XHTML los tsim lawv cov nplooj ntawv web.
Thaum koj sau XHTML, koj yuav tsum sau tag nrho cov cim npe hauv lowercase vim XHTML yog muaj case sensitive. Qhov no txhais tau tias cov yog txawv dua li hauv XHTML. Koj yuav tsum tau qhia meej rau koj li cas koj Xeem XHTML webpage thiab tsuas yog siv cov cim me xwb. Qhov kev cai nruj heev yog qhov txiaj ntsim rau ntau lub vev xaib tshiab. Siv tsis tau sau ntawv cim nrog ib qho sib txig ntawm qhov txo qis thiab hnyav, lawv paub tias muaj ib hom ntawv nruj uas yuav tsum tau ua. Rau txhua tus neeg uas txiav lawv cov hniav hauv web tsim thaum XHTML tau nrov, heev lub tswv yim tias tus cim kos npe yuav yog ib qho sib xyaw ntawm cov tsiaj ntawv qis thiab cov ntawv qis qis txawv teb chaws thiab tsis ncaj ncees lawm.
HTML5 Xoob Xoob
Lub versions ntawm HTML ua ntej XHTML tsis yog case-sensitive. HTML5 ua raws li ntawd qhov kev lig kev cai thiab mus deb ntawm cov kev cai nruj formatting ntawm XHTML.
Yog li HTML 5, tsis zoo li XHTML, tsis yog case-sensitive. Qhov no txhais tau hais tias thiab thiab yog tag nrho tib yam hauv HTML 5. Yog tias qhov no zoo li chaos rau koj, Kuv xav tias koj qhov mob.
Lub tswv yim tom qab HTML5 tsis yog cov ntaub ntawv rhiab yog ua kom yooj yim rau cov neeg ua haujlwm tshiab web kawm kom paub cov lus, tab sis raws li ib tug neeg uas qhia cov qauv web tsim rau cov tub ntxhais kawm ntawv, kuv tuaj yeem ua pov thawj rau qhov tseeb tias qhov no tsis yog qhov teeb meem txhua.
Tau muab cov tub ntxhais kawm ntawv tshiab rau cov qauv tsim cov cai, xws li "ib txwm sau koj li HTML raws li qis", pab lawv thaum lawv sim kawm txhua yam uas lawv xav tau los kawm ua tus tsim web site. Muab lawv cov kev cai uas yoojyim dhau los yeej ua rau cov neeg kawm ntau yam tsis ua rau lawv yooj yim dua.
Kuv nyiam qhov tseeb tias cov sau phau ntawv ntawm HTML5 spec tau sim pab nws yooj yim kawm los ntawm kev ua nws ntau tau yooj yim, tab sis, nyob rau hauv no lom, kuv xav tias lawv ua ib misstep.
Convention hauv HTML 5 yog siv Cov Txuj Ci Tshiab
Thaum nws siv tau los sau cov cim npe uas siv cov lus koj nyiam thaum sau ntawv HTML 5, lub convention yog siv tag nrho cov tsiaj ntawv cim npe thiab cov cwj pwm. Qhov no yog ib feem ntau vim hais tias muaj ntau ntau qhov web site developers uas nyob los ntawm cov hnub ntawm XHTML nruj tau nqa cov kev coj ua zoo tshaj plaws rau HTML5 (thiab dhau). Cov neeg ua hauj lwm hauv web tsis paub hais tias cov ntawv ua cov ntawv loj thiab cov tsiaj ntawv lowercase siv tau rau hauv HTML5 hnub no, lawv yuav lo nrog lawv paub, uas yog cov tsiaj ntawv tsawg dua.
Muaj ntau qhov kev tsim web tsim muaj kev kawm los ntawm lwm tus, tshwj xeeb tshaj yog los ntawm cov neeg uas paub ntau dua hauv kev lag luam. Qhov no txhais tau hais tias cov neeg tsim tawm tshiab hauv web yuav saib xyuas cov cai ntawm cov tub txawg hnub nyoog thiab pom tag nrho cov tsiaj ntawv tsawg. Yog hais tias lawv ua raws li cov cai no, nws txhais tau hais tias lawv yuav sau HTML5 hauv tag nrho cov kev txo nqi qis. Qhov no yog qhov zoo li zoo li tau tshwm sim hnub no.
Txoj Kev Zoo Tshaj Plaws rau Lettercasing
Nyob rau hauv kuv tus kheej kev, kuv pom nws zoo tshaj plaws kom nco ntsoov siv cov tsiaj ntawv qis rau HTML code nrog rau cov npe cov npe. Vim tias qee tus neeg zov me nyuam yog cov ntaub ntawv-thaum nws tuaj cuag cov filenames (piv txwv li, "logo.jpg" yuav pom ntau dua "logo.JPG"), yog tias koj muaj haujlwm ua haujlwm uas koj siv cov tsiaj ntawv tsawg dua, koj tsis tas yuav nug qhov twg yog qhov teeb meem yog tias koj muaj teeb meem xws li cov duab uas ploj lawm . Yog tias koj pheej siv cov ntawv sau ntawv txo nqi, koj tuaj yeem txo qhov uas yog qhov teeb meem thaum koj tawm tsam cov teeb meem hauv tsev kawm ntawv. Qhov no yog qhov haujlwm uas kuv qhia rau kuv cov menyuam kawm ntawv thiab cov uas kuv siv rau hauv kuv tus kheej lub web tsim haujlwm.
