Ukuba ubona ikhowudi yomthombo wekhasi lewebhu, uza kubona uxwebhu olwenziwe ngezinto ezahlukeneyo ze-HTML, kubandakanywa iziqendu, izihloko, uluhlu, izixhumanisi, imifanekiso kunye nokunye. Zonke ezi zinto zinikezelwa ngumkhangeli kwiskrini somvakatye njengenxalenye yokuboniswa kwewebhusayithi. Into enye ongayifumana kwikhowudi ye-HTML engakhange ifakwe kwiskrini somntu yinto eyaziwa ngokuba yi "HTML comments".
Uphi uluvo?

Uninzi lweelwimi zeprogram zinamazwana, zisetyenziswa ngumqhubi wekhowudi enye okanye ngaphezulu kweyodwa, kwesi sizathu esilandelayo:
- Chaza kwaye uchaze ikhowudi eyinkimbinkimbi kumntu onokufuneka asebenze kwixesha elizayo - kuquka yena ngokwakhe! Baya kubuya kwikhowudi 3 okanye 6 yeenyanga ezili-12 okanye ngaphezulu kamva kwaye khumbula ukuba kutheni benza okuthile ngendlela ethile. Amazwana anokunceda ukuphendula imibuzo yabo kwaye ukhumbuze ukuba beyiphi ingqondo yabo xa beqala ukuphucula elo phepha.
- Nika iinkcukacha malunga nokuba ikhowudi yahlelwa okanye iyahlolwa. Oku kunokuba luncedo ulwazi kunye nokwenza ngendlela efana nelo lophuhliso lwaloo ndawo ekugqibeleni isayithi iqhutyelwe kuyo.
- Susa izicwangciso zekhowudi, kodwa ziyeke zifumaneke ukuze zisebenzise kamva. Oku kudlalwa rhoqo ngexesha lokuvavanywa kwesayithi kunye nokuphulwa komsebenzi. Ukuba unengxaki kwisayithi kwaye ungaqinisekanga oko kukubangela, unokwenza iziphakamiso zecandelo elinye ngexesha ukuza kubantwana kunye nokuchonga umcimbi, kwaye ke usebenze ukulungiswa kuyo nayiphi na ingxaki onayo.
- Xoxa nabanye abathuthukisi abasebenza kwikhowudi. Oku kuya kwenzeka ngexesha lophuhliso njengendlela yokwabelana ngolwazi nabanye abasebenzisa ikhowudi ngexesha elifanayo. Ukuba ezi ngxelo zixubusha ingxoxo kuphela, kuyona ndlela ibhetele ukuyisusa kwi khowudi ngaphambi kokuba isayithi iqaliswe.
Ngokwesiko, izimvo kwi-HTML zisetyenziselwa phantse naziphi na izinto, ukusuka kwiinkcazo zetekisi eziyinkimbinkimbi kwiingxelo ezifundisayo zomxholo wephepha ngokwayo.

Uninzi lwabafundi balwazi ukubaluleka kwamazwana ancedo . Ikhowudi ephawulayo yenza kube lula ukuba ikhowudi idluliselwe kwelinye ilungu leqela kwelinye. Amazwana anokunceda iqela le-QA ukuvavanya ikhowudi, kuba iyakwazi ukuxelela oko umqulunqi obekujoliswe kuyo-nangona ingazange ifumaneke. Ngelishwa, ngokuthandwa kwamapulatifomu ebhaliweyo kwiwebhsayithi njenge-Wordpress, evumela ukuba uvuke kwaye usebenze ngomxholo okhethiweyo olawula ezininzi, ukuba awunjalo konke, i-HTML yakho, izimvo azisebenzisi rhoqo ngamaqela ewebhu.

Isixhobo esibubonayo sibonisa isithonjana esincinci ukubonisa ukuba kukho impendulo. Ukuba umyili akayi kuvulwa ngokwasemzimbeni, akanakukubona. Kwaye kwimeko yecandelo elingentla, kunokubangela iingxaki ukuba uhlela iphepha kwaye ukuhlela kubhalwe ngaphezulu kwirejista ekhankanywe kwikhomenti.
Yintoni Enokuyenza?
- Bhala izimvo ezinentsingiselo nezifanelekileyo. Musa ukulindela abanye abantu ukuba bafunde iimpendulo zakho ukuba zide kakhulu okanye azibandakanyi ulwazi oluncedo.
