Ithuluzi eliyinhloko ngokudala amakhasi ewebhu wanoma yimuphi Izinga kuyinto uxhumano ulimi yomdwebo, nobe ulimi lwemibhalo yewebhu (HTML). Zonke ulimi design esibizwa «tags" ezichaza ukubonisa umbhalo ekhasini kanye nomhleli salo lonke ikhasi html.

Kungani usebenzisa tags? Iqiniso liwukuthi noma yimuphi umqulu olutholakala kukhompuyutha yakho, usethe uhlelo oluthile, bese ukuvula iningi amacala, kubalulekile ukuthi uhlelo lapho yadalwa, noma ezifanayo.

Njengoba sekunama-the Internet kukhona umbuzo ku ukudluliswa lesifanele kwemibhalo phakathi kwabasebenzisi lwamakhompyutha, ngamunye okungenzeka kukhompyutha yakho iqoqo eliyingqayizivele izinhlelo efakiwe. Ngaphezu kwalokho, ezisekelweni ngokwabo ingahluka - hhayi kuwo wonke amakhompyutha ixhunywe kwinethiwekhi ezisebenzayo-Windows. Ngakho, incwadi eyatholakala kuwebhu kalula asuswe umsebenzisi esithile.

Ukuze ukuthi iyiphi dokhumenti kahle neyaziwayo kunoma iyiphi ikhompyutha, kungakhathaliseki platform kanye iphakethe izinhlelo efakwe, futhi lakhiwe uxhumano ulimi yomdwebo-HTML. Emzimbeni idokhumenti wethula imiklamo ekhethekile, ababiziweyo tags, futhi yonke idokhumenti lilondolozwe ifomethi yamagama acacile, elitholakala kuwo wonke amakhompyutha.

-HTML akuyona ulimi lokwakha ngomqondo ezivamile. Tags kuphela isimiso esikhethekile, isiphequluli indlela yokubonisa umbhalo ekhasini. Isiphequluli ubachazela yomdwebo ulimi kwaqanjwa futhi inikeza ikhasi eliceliwe.

Isidlulisilwazi yomdwebo ulimi kuhlanganisa ezihlukahlukene tags okuqondene amaqembu ahlukene. Elinye lamaqembu wukuntuleka tags Ifomethi yombhalo. Ziqukethe lonke ulwazi mayelana nendlela umbhalo kumele ibukeke: ukuqondanisa yakhe, usayizi, ifonti isitayela lokubhala, indents, izinhlu, futhi iqukethe nezinye izinto eziningi. Ukufomatha umbhalo icaciswe ithegi izimfanelo futhi lilondolozwe ngaphakathi ithegi. Nokho, kufanele sikhumbule ukuthi ubuchwepheshe besimanje ukudala amakhasi ewebhu ukunqunywa konke ukufometha umbhalo nokubonisa ikhasi sisonke ngendlela ehlukile ifayela Cascading Style ishidi izingxenye okufanayo, okuyinto ingaqukatha ukufomatha tags umbhalo, manje kuyaqabukela asetshenziswa.

Izizathu zalokhu mkhuba ukuthi ukusetshenziswa design web wendlale isitayela amashidi (SCC) ekudalweni amawebhusayithi Kuyinto elula kakhulu. Engingakusho nje athwale CSS-ifayela zonke yokubhalisa kanye ixhume wonke amakhasi kusayithi lakho (noma ezinye). La makhasi uyohlale zibukeka zifana. Uma kudingeka, wenze izinguquko ekuklanyweni izakhi ezithile kwekhasi (isihloko yesibili tier, isibonelo) yanele ukuba ushintshe entry eyodwa kuphela ifayela CSS. Shintsha zonke izihloko lesibili level (h2) kuwo wonke amakhasi exhunywe kwi-CSS. Ikakhulukazi, ukuze wenze sematheni oluhlaza ngokwanele efayeleni CSS ukubhalisa umugqa eyodwa kuphela:

h2 {sefonti umbala: oluhlaza}

Nansi indlela isigaba kuyokwenziwa kuchazwe, kwesokudla siqondile, on isizinda obomvu, umbhalo blue:

p {umbala ongemuva: obomvu; umbala: okuluhlaza okwesibhakabhaka; umbhalo-ukuqondanisa: kwesokudla}

Zonke tags ifu iqukethe izakhiwo eziningi, kodwa ekutadisheni kwabo kanye cwaningo izici ukusetshenziswa kwabo liyadingeka nakanjani ukuze kube umklami sewebhu, futhi ikakhulukazi coder, okuyinto ngaphandle kwabo ngeke ikwazi ukumaka ikhasi.

Ngaphezu kwalokho kufanele sikukhumbule ngaso sonke isikhathi ukuthi kungani eminyakeni yamuva nje kuye kwaba khona ocacile ku "izindawo", elalikade azange abe njengoba kwakungekho khona ehlukile futhi kusakhiwo, umklamo kanye izinhlelo yamakhasi ewebhu.

Lapho edala ubuchwepheshe sina izindawo ezisetshenziswa athé ukwehluka izinhlelo yendabuko ayingxenye iphakheji kwemibhalo ehhovisi. Ngisho ukudala ikhasi elula yewebhu usebenzisa html tags.
