Kodi ma HTML ndi chiyani?
Pamene muwona tsamba lamasamba mumasakatuli, mukuwona zowonetseratu za zomwe pulogalamuyo (msakatuli) akuwonetsera malingana ndi code ya tsamba lapadera. Ngati muwona tsamba loyambira la tsambali, mudzawona chikalata chopanga zinthu zosiyanasiyana za HTML, kuphatikiza ndime, mitu, mndandanda, zizindikiro, zithunzi ndi zina. Zonsezi zimasuliridwa ndi osatsegula pawindo la mlendo monga gawo lawonetsetsa webusaitiyi. Chinthu chimodzi chimene mungapeze mu code HTML zomwe sizinapangidwe pawonekedwe la munthu ndi zomwe zimatchedwa "ndemanga za HTML".
Kodi Ndemanga Ndi Yanji?
Ndemanga ndi mndandanda wa code mkati mwa HTML, XML, kapena CSS yomwe siyiyang'ana kapena ikuchitidwa ndi osatsegula kapena woyimitsa. Zangowonjezedwa mu code kuti zidziwitse za chikhomo kapena malingaliro ena kuchokera kwa omanga makalata.
Mitundu yambiri yopanga mapulogalamu ali ndi ndemanga, imagwiritsidwa ntchito ndi wopanga makinawo kwa chimodzi kapena zingapo, pazifukwa zotsatirazi:
- Fotokozani ndi kufotokozera zilembo zovuta kwa wina yemwe angafunikire kugwira ntchito mtsogolo - kuphatikizapo okha! Angabwererenso ku code 3 kapena 6 ya miyezi 12 kapena patapita nthawi ndikumbukira chifukwa chake anachita chinachake mwanjira inayake. Ndemanga zitha kuthandizira kuyankha mafunso awo ndikuwakumbutsa komwe anali malingaliro awo pamene analikuyamba kulumikiza tsamba.
- Perekani tsatanetsatane wa momwe kachidindo kanasinthidwe kapena kuyang'aniridwa. Izi zingakhale zothandiza zodziwikiratu ndikuchita mofanana ndi chipika cha chitukuko cha malo omwe ntchitoyo inagwiritsidwira ntchito.
- Chotsani magawo a khodi, koma asiye iwo kuti agwiritsidwe ntchito mtsogolo. Izi kawirikawiri zimachitika panthawi yoyezetsa malo ndi kukonza machitidwe. Ngati muli ndi vuto pa webusaitiyi ndipo simukudziwa chomwe chikuchititsa, mukhoza kufotokoza ndondomeko imodzi pa nthawi yoti mudziwe ndi kuzindikira vutoli, ndiyeno yesetsani kuthetsa mavuto omwe muli nawo.
- Kambiranani ndi omanga ena ogwira ntchito pa code. Izi zikhoza kuchitika pa chitukuko monga njira yogawana zinthu ndi ena ogwira ntchito pa code nthawi yomweyo. Ngati ndemanga izi ndi zokambirana zachitukuko, ndi njira yabwino kwambiri yochotseramo malamulo asanayambe malo.
Mwachikhalidwe, ndemanga mu HTML zimagwiritsidwa ntchito pazinthu zilizonse, kuchokera ku ndondomeko ya zovuta zamatabwa ndi mafotokozedwe okhudzana ndi zomwe zili patsamba. Popeza ndemanga sizinapangidwe mu osatsegula, mukhoza kuziwonjezera pena paliponse mu HTML ndipo mulibe nkhaŵa za zomwe zidzachitike pamene tsamba liwonedwe ndi kasitomala.
Mmene Mungalembere Malingaliro
Kulemba ndemanga mu HTML, XHTML, ndi XML n'kosavuta. Lembani mndandanda wazomwe mukufuna kufotokozera ndi izi:
ndi ->Monga momwe mukuonera, ndemanga izi zimayamba ndi "zochepa kuposa chizindikiro", kuphatikizapo chidwi ndi mfundo ziwiri. Ndemangayo imathera ndi zina zowonjezera ziwiri ndi "zazikulu kuposa: chizindikiro. Pakati pa olembawo mukhoza kulemba chirichonse chomwe mukufuna kupanga thupi la ndemanga.
Mu CSS, ndi zosiyana kwambiri, pogwiritsa ntchito ma code C m'malo mwa HTML Mukuyamba ndi patsogolo slash ndiyeno asterisk. Mukutsutsa ndemanga ndi kutsutsana kwa izo, asterisk ikutsatiridwa ndi forward slash.

Ambiri mwa mapulogalamu amadziwa kufunika kwa ndemanga zothandiza . Nkhoswe yamalongosola imapangitsa kuti zikhale zosavuta kuti chilolezocho chichotsedwe kuchokera ku membala wina kupita ku wina. Ndemanga zimakuthandizani QA timu kuti tiyese ndondomekoyi, chifukwa ikhonza kudziwa zomwe woyimanga akufuna - ngakhale kuti sizinachitike. Mwamwayi, ndi kutchuka kwa nsanamira zolemba ma webusaiti monga Wordpress, zomwe zimakulolani kudzuka ndi kuthamanga ndi mutu wosankhidwa womwe umagwira ntchito zambiri, ngati si zonse, za HTML, ndemanga sizigwiritsidwa ntchito nthawi zambiri ndi ma webusaiti. Izi ndizo chifukwa ndemangazo ndizovuta kuziwona muzitsulo zambiri zojambula ngati simukugwira ntchito mwachindunji ndi code. Mwachitsanzo, m'malo mowona, pamwamba pa tsamba lamasamba:
Chida chowonetsera chikuwonetsa chidindo chochepa kuti chisonyeze kuti pali ndemanga. Ngati wokonzayo sangatsegule ndemanga, sangathe kuziwona. Ndipo pa tsamba ili pamwamba, zingayambitse mavuto ngati akusintha pepala ndipo kusinthidwa kwatha kulembedwa ndi script yomwe yatchulidwa mu ndemanga.
Kodi N'chiyani Chingachitike?
- Lembani ndemanga zothandiza komanso zothandiza. Musamayembekezere anthu ena kuti awerenge ndemanga zanu ngati atalika kwambiri kapena osaphatikizapo zowathandiza.
- Monga wogwirizira, nthawi zonse muyenera kuyang'ana ndemanga zilizonse zomwe mumaziwona patsamba.
- Gwiritsani ntchito zida zoperekedwa ndi mapulogalamu olemba omwe amakulolani kuti muwonjezere ndemanga.
- Gwiritsani ntchito kayendedwe ka zinthu kuti muwonetse momwe masambawo asinthidwira.
Ngakhale ngati ndinu nokha amene amasintha mawebusaiti anu, ndemanga zingakhale zothandiza. Ngati mutasintha tsamba lophweka kamodzi pachaka, n'zosavuta kuiwala momwe munamangira tebulo kapena kuika CSS pamodzi. Ndi ndemanga, simukuyenera kukumbukira, monga momwe zinalembedwera pomwepo.
