Phezulu kwekhasi CSS: ukubeka umxholo

Uluhlu lweCSS luhlala lusetsaleni. Naliphi na imigca egciniweyo - ubuchule bomthuthukisi. Imithetho yendlela yokubonelela inikezela ngokwaneleyo ukhetho lokunika iphepha libe yinto epholileyo kwiisombululo seskrini. Kodwa nayiphi na into yendlela yokwenza isoloko isingxande apho ilungiselelo lolwazi lulawulwa yimithetho yeCSS.

Ukufakwa kwamacala kuwo onke macala kubalulekile kwinqanaba ngalinye lephepha xa limeleleke, kwaye umgama ophezulu kwiCSS uchazwa ngokukodwa, kuba kubalulekile kwizinto ezihlukeneyo, ngokukodwa okuphantsi kwezantsi.

Imigaqo yokubeka esiseko

Inxalenye yebhloko inomgaqo wokungeniswa kwindalo evela kumacandelo apho umgama ukhona khona, umgaqo wokungena kwizinto eziphakathi kwawo (ukugqithisa) kunye nobubanzi bomda (umda), onokusetyenziswa kwakhona.

Okubaluleka ngokukhethekileyo kukukhutshwa okuvela phezulu. I-CSS ngaphakathi kwebhloko idibanisa imithetho ye-indentation yangaphakathi kwimimiselo yezinto ezizimeleyo kunye nezimeko ezikulo bhloko.

Umkhuba oqhelekileyo wee-CSS-imithetho: ungacacisa indent kuzo zonke izikhokelo ngokulinganayo, ngeendidi eziphezulu phezulu / ezantsi kunye nokunene / ezisekhohlo okanye kwicala ngalinye. Ngokomzekelo,

• Umda: 10px;
• Ipadding: 10px20px;
• Ukupasa: 10px20px30px40px.

Kwimeko yokuqala, loo nto ifunyenwe kumacala omgca wangaphandle apho ikhona khona. Kwimeko yesibini, i-padding phezulu kunye nezantsi iphantsi kwe-10px, iindawo eziselunxwemeni nasekunene zi-20px. Kwimeko yesithathu, ubungakanani bendoda ekhonjisiweyo luboniswe kuwo onke macala: phezulu, kunene, ngasezantsi nakwesobunxele.

Kuzo zonke iimeko, umda ongaphezulu kweCSS ngu-10 px.

Imithetho ethintsha indawo yezinto

Ukuba indawo yendawo ayiyiyo yonke indawo, itholakala ngokulandelelana jikelele kwendlela yokwenza iphepha.

Ukuba uchaza indlomelo ngaphezulu kwe CSS kwinqalo ye scCurrInfo, ithagethi iya ku fi kelelwa, kwaye ukuba i-level li, akukho.

Kulo mzekelo, usebenzisa umgaqo wokubamba: 40px; Kudinga ukuncitshiswa okwaneleyo kwemithetho yobubanzi kunye nokuphakama ngo-80px. Ngaphandle koko, ubungakanani bebloko ye scCurrInfo ziya kuphuma ngaphandle kwebhloko elingaphandle.

Ukuba ususa umyalelo wokubambisa kwi-definition ye-scCurrInfo, kodwa wongeze ngexabiso le-20px kwenkcazo yesitayela yoluhlu lwempahla, sithola nje indent evela phezulu. I-CSS ayiyi kusebenzisa eli xabiso kwamanye amaqela.

Ngokwemvelo, oku kusetyenziselwa ukubaluleka kokusebenza kwendawo yokusebenza okusebenzayo kusebenza kwisilwanyana ngasinye.

Isenzo esiqhelekileyo sokufometha umxholo

Abanye abaphuhlisi bafezekisa ukugqibelela ngokuthayipha iphepha ngamanqaku ebloko. Kubonakala ukuba yinkqubo yeklasi ukuqala ukusuka kwitheyibhile uze uqedele inkqubo yakho yemfundo kwiibhloko.

Inkululeko ekhoyo kwindawo yokubeka ibhloko iyamangalisa, kwaye ingcamango yonjiniyela ayinakupheleliswa kwimithetho ethe ngqo yimiba: imigca kuphela, iiseli kuphela, zidibanisa kuphela ngokuzenzekelayo kwaye zenzeke. Akukho nto ivela kwiingcamango zesondlo.

Okwangoku, iitheyibhile, ngaphezu kweengxaki ezingekho phantsi, kukho ezininzi iingeniso ezifanelekileyo. Ukudala indalo ukusuka phezulu, i-CSS ithatha ingqalelo kwi-indents ngakwesobunxele, kunene (ezansi-le yithuba elikhethekileyo). Itheyibhile iiseli zeemithetho zivumela ukuba ulawule ukulungelelanisa kokubini kunye nangokungqongqo. Ukusebenzisa izitayela zomgca, ukudibanisa kunye nezitayela zeseli, unokudala imibono enomxholo obunzima.

Ukubonakaliswa okuqhelekileyo kwiphepha ngeendlela zamacangca (ukucwangciswa kwebhloko) akukuthinteli ukuba lubekwe kwifom yetafile. Ezi ziyi-rectangles, kodwa zithengisa iiseli, oko kukuthi, zinemithetho yazo ehambisana nemithetho yeebhloko.

Ukumisa ngokupheleleyo

; Vimba kunye nomgaqo wePOSITION: ngokupheleleyo ; Kuya kuba kwindawo ebekwe ngamanqwanqwa ayo ngokubhekiselele kwibloko apho ikhona khona.

I-character character of CSS imigaqo "isenzo esona sigqibo esona sihle" kwiimeko ezininzi, ngokukodwa xa kuhambelana nokuhambelana nesiphequluli esifanelekileyo kwaye ulungiso luyenziwe ngesandla, lukhethwa ukuba lufunde iincwadi zokufunda ezipheleleyo.

Ukusebenzisa iitheyibhile kukukhokelela kwiingxaki ekuhambeni kwezinto eziphakathi kweeseli. Ukufuduka okufanayo kwiibhloko akusoloko kuthintela zonke izinto. Ukuvavanya, unokufezekisa umphumo oyifunayo. Umsebenzi ongathandekiyo: indlela yokukrazula i-indent ukusuka phezulu, i-CSS ayisoloko isisombulula.

Kwezinye iimeko, xa kukho imfuneko yokwenza izinto zekhasi ezinzulu kwiinkqubo eziphathekayo zokulawulwa kwendawo, kuyona kunjalo kuyimfuneko ukuba ingqalelo ingqalelo kuphela kwindlela yokuhlola, kodwa kwakhona ukujonga kumava oogxa.
