Mayelana nalolu hlelo lokusebenza

HTML
Okokufundisa kwe-HTML noma okokufundisa kwe-HTML 5 kunikeza imiqondo eyisisekelo nethuthukile ye-HTML. Isifundo sethu se-HTML senzelwe abaqalayo nezingcweti. Esifundweni sethu, sonke isihloko sinikezwa isinyathelo ngesinyathelo ukuze usifunde ngendlela elula kakhulu. Uma umusha ekufundeni i-HTML, khona-ke ungafunda i-HTML kusukela kokuyisisekelo kuya ezingeni lochwepheshe futhi ngemva kokufunda i-HTML nge-CSS ne-JavaScript uzokwazi ukudala iwebhusayithi yakho esebenzisanayo nenamandla.

Kulolu hlelo lokusebenza, uzothola izibonelo eziningi ze-HTML, okungenani isibonelo esisodwa sesihloko ngasinye esinencazelo. Ungakwazi futhi ukuhlela nokusebenzisa lezi zibonelo, ngomhleli wethu we-HTML. Ukufunda i-HTML kuyajabulisa, futhi kulula kakhulu ukuyifunda.

- I-HTML imele Ulimi LweMarkup HyperText.
- I-HTML isetshenziselwa ukwakha amakhasi ewebhu nezinhlelo zokusebenza zewebhu.
- I-HTML iwulimi olusetshenziswa kakhulu kuwebhu.
- Singakha iwebhusayithi emile nge-HTML kuphela.
- Ngobuchwepheshe, i-HTML iwulimi lweMarkup kunolimi lokuhlela.

CSS
Okokufundisa kwe-CSS noma okokufundisa kwe-CSS 3 kunikeza imiqondo eyisisekelo nethuthukile yobuchwepheshe be-CSS. Isifundo sethu se-CSS senzelwe abaqalayo nabachwepheshe. Amaphuzu amakhulu we-CSS anikezwe ngezansi:
- I-CSS imele i-Cascading Style Sheet.
- I-CSS isetshenziselwa ukuklama amathegi e-HTML.
- I-CSS iwulimi olusetshenziswa kakhulu kuwebhu.
- I-HTML, i-CSS ne-JavaScript isetshenziselwa ukuklama iwebhu. Isiza abaklami bewebhu ukusebenzisa isitayela kumathegi e-HTML.

I-CSS imele i-Cascading Style Sheets. Kuwulimi lweshidi lesitayela olusetshenziswa ukuchaza ukubukeka nokufometha kwedokhumenti ebhalwe ngolimi lokumaka. Inikeza isici esengeziwe ku-HTML. Ngokuvamile isetshenziswa ne-HTML ukushintsha isitayela samakhasi ewebhu nezixhumi ezibonakalayo zomsebenzisi. Ingasetshenziswa nanoma yiluphi uhlobo lwemibhalo ye-XML ehlanganisa i-XML esobala, i-SVG ne-XUL.

I-CSS isetshenziswa kanye ne-HTML ne-JavaScript kumawebhusayithi amaningi ukuze kwakheke izixhumanisi zomsebenzisi zezinhlelo zokusebenza zewebhu kanye nezindawo zabasebenzisi zezinhlelo zokusebenza eziningi zeselula.

Ngaphambi kwe-CSS, amathegi afana nefonti, umbala, isitayela sangemuva, ukuqondanisa kwezakhi, umngcele nosayizi bekufanele kuphindwe kuwo wonke amakhasi ewebhu. Lena kwakuyinqubo ende kakhulu. Isibonelo: Uma uthuthukisa iwebhusayithi enkulu lapho amafonti nolwazi lombala lwengezwa ekhasini ngalinye. I-CSS idalwe ukuxazulula le nkinga.

I-Javascript
I-JavaScript (js) iwulimi lokuhlela olugxile entweni enesisindo esincane olusetshenziswa amawebhusayithi ambalwa ekubhaleni amakhasi ewebhu. Iwulimi olutolikiwe, olugcwele uhlelo oluvumela ukusebenzisana okunamandla kumawebhusayithi uma kusetshenziswa kudokhumenti ye-HTML. Yethulwa ngonyaka ka-1995. Kusukela lapho, iye yamukelwa yizo zonke ezinye iziphequluli zewebhu ezinemifanekiso. Nge-JavaScript, abasebenzisi bangakha izinhlelo zokusebenza zewebhu zesimanje ukuze zihlanganyele ngqo ngaphandle kokulayisha kabusha ikhasi ngaso sonke isikhathi. Iwebhusayithi yendabuko isebenzisa i-js ukuhlinzeka ngezindlela ezimbalwa zokusebenzisana nokubalula.

Noma kunjalo, i-JavaScript ayinakho ukuxhumana nolimi lohlelo lwe-Java. Igama laphakanyiswa futhi lanikezwa ngezikhathi lapho i-Java ithola ukuduma emakethe. Ngokungeziwe kuziphequluli zewebhu, isizindalwazi esifana ne-CouchDB ne-MongoDB zisebenzisa i-JavaScript njengolimi lwazo lokubhala nokubuza.
- Zonke iziphequluli zewebhu ezidumile zisekela i-JavaScript njengoba zinikeza izimo zokusebenza ezakhelwe ngaphakathi.
- I-JavaScript ilandela i-syntax nesakhiwo solimi lokuhlela lwe-C. Ngakho, kuwulimi lokuhlela oluhlelekile.
- I-JavaScript iwulimi oluthayiphiwe ngendlela ebuthakathaka, lapho izinhlobo ezithile zisakazwa khona ngokungagunci (ngokuya ngomsebenzi).
- I-JavaScript iwulimi lohlelo olugxile entweni olusebenzisa ama-prototypes kunokusebenzisa amakilasi ukuthola ifa.
