Faiga fa'apipi'i

Fa'aoga la matou telefoni feavea'i-muamua flexbox grid e fau ai fa'ata'ita'iga o foliga ma lapopo'a uma fa'afetai i le faiga o koluma e sefululua, ono fa'aletonu e tali atu ai, Sass fesuia'i ma fa'afefiloi, ma le tele o vasega na mua'i fa'avasegaina.

Faataitaiga

E fa'aogaina e le Bootstrap's grid system se fa'asologa o koneteina, laina, ma koluma e fa'atulaga ma fa'aoga mea. E fausia i le flexbox ma e tali atoatoa. O loʻo i lalo se faʻataʻitaʻiga ma se faʻamatalaga loloto mo le auala e faʻapipiʻi faʻatasi ai le faʻaogaina o le grid system.

O le fa'ata'ita'iga o lo'o i luga e fa'atupuina ai ni koluma tutusa-lautele se tolu i luga o masini uma ma va'aiga va'aiga e fa'aaoga ai a tatou vasega fa'avasega. O na koluma e totonugalemu i le itulau ma le matua .container.

E faapefea ona galue

O le malepe i lalo, o le auala lea e faʻapipiʻi faʻatasi ai le faiga faʻasologa:

  • O la matou fa'asologa e lagolagoina ono tali fa'amuta . O va'aiga e fa'avae i luga o min-widthfa'asalalauga fa'asalalauga, o lona uiga e a'afia ai lena va'aiga ma mea uma o lo'o i luga atu (fa'ata'ita'iga, .col-sm-4e fa'atatau ile sm, md, lg, xl, ma le xxl). O lona uiga e mafai ona e pulea le fa'avasegaina o koneteina ma le koluma ma amioga i vaega ta'itasi.

  • Container fa'atotonugalemu ma fa'alava faalava au mea. Fa'aoga .containermo le lautele pika tali, .container-fluidmo width: 100%va'aiga uma ma masini, po'o se atigipusa tali (fa'ata'ita'iga, .container-md) mo le tu'ufa'atasiga o le vai ma le pika lautele.

  • O laina o afifi mo koluma. O koluma ta'itasi e fa'ata'atia padding(ta'ua o le alavai) mo le fa'atonutonuina o le va i le va. Ona paddingfa'afeagai lea i luga o laina i laina le lelei e fa'amautinoa ai o mea o lo'o i totonu o au koluma o lo'o fa'aoga tonu ile itu agavale. E lagolagoina fo'i e laina vasega fetu'una'iga e fa'aoga tutusa le fa'avasegaina o koluma ma vasega alavai e sui ai le va o au mea.

  • Koluma e matua fetuutuunai. E 12 fa'ata'ita'iga koluma o lo'o avanoa ile laina, e mafai ai ona e faia ni tu'ufa'atasiga 'ese'ese o elemene e va'aia so'o se numera o koluma. O vasega koluma o lo'o fa'ailoa mai ai le aofa'i o koluma fa'ata'ita'i e fa'alava (fa'ata'ita'iga, col-4fa'alava). widths o lo'o fa'atulaga i pasene ina ia tutusa lava lou fa'atusatusaga.

  • E talileleia fo'i alavai ma mafai ona fa'avasega. E avanoa vasega alavai i vaega uma e momotu ai, e tutusa uma lapo'a ma o tatou pito ma le va o padding . Suia alavai faalava i .gx-*vasega, alavai sa'o ile .gy-*, po o alavai uma e iai .g-*vasega. .g-0e avanoa foi e aveese ai alavai.

  • Sass fesuia'i, fa'afanua, ma fefiloi fa'amalo le fa'asologa. Afai e te le manaʻo e faʻaaoga vasega faʻavasega muamua i Bootstrap, e mafai ona e faʻaogaina le matou faʻasologa o Sass e fai ai sau lava faʻailoga faʻailoga. Matou te fa'aaofia fo'i nisi o mea totino a le CSS e fa'aaoga ai nei suiga Sass mo le sili atu ona fetu'una'i mo oe.

Ia nofouta i tapula'a ma pusi i luga o le flexbox , pei o le le mafai ona fa'aogaina nisi o elemene HTML e fai ma koneteina fe'avea'i .

Grid filifiliga

E mafai ona fetuutuuna'i le faiga fa'asologa a Bootstrap i vaega uma e ono e le mafai, ma so'o se va'aiga e te fa'avasegaina. O fa'asologa fa'asologa e ono e fa'apea:

  • Laiti fa'aopoopo (xs)
  • Laiti (sm)
  • Medium (md)
  • Tele (lg)
  • Tele tele (xl)
  • Lapopo'a fa'aopoopo (xxl)

E pei ona ta'ua i luga, o nei vaega ta'itasi e iai a latou koneteina, fa'ailoga tulaga ese o le vasega, ma suiga. O le auala lea e suia ai le fa'asologa i nei va'aiga:

Fa'aoga vasega koluma fa'apitoa mo le fa'avasegaina o koluma e aunoa ma se vasega fa'anumera manino e pei o .col-sm-6.

Tutusa-lautele

Mo se faʻataʻitaʻiga, e lua faʻasologa faʻasologa e faʻaoga i masini uma ma vaʻaiga, mai xsi le xxl. Fa'aopoopo so'o se numera o vasega fa'aitiiti iunite mo va'aiga ta'itasi e te mana'omia ma o le a tutusa le lautele o koluma uma.

Vasega tali atu

O le fa'asologa o Bootstrap e aofia ai vaega e ono o vasega ua uma ona fa'ata'atia mo le fausiaina o fa'ata'ita'iga lavelave. Fa'apitoa le lapopoa o au koluma i luga o masini fa'aopoopo laiti, la'ititi, feololo, lapo'a, po'o masini tetele e tusa lava pe e te mana'o e fetaui.

Tulaga uma

Mo grids e tutusa mai le laʻititi o masini i le tele, faʻaaoga le .colma .col-*vasega. Fa'ailoa se vasega faanumera pe ae mana'omia se koluma fa'apitoa; a leai, lagona le saoloto e pipii i .col.

Fa'avasega le fa'asologa

I le fa'aogaina o la matou fa'asologa Sass fesuiaiga ma fa'afanua, e mafai ona fa'avasega atoatoa vasega fa'avasega. Suia le numera o vaega, le tele o fesili a le aufaasālalau, ma le lautele o koneteina—ona toe tuufaatasia lea.

Koluma ma alavai

Ole numera o koluma fa'asologa e mafai ona suia e ala i fesuiaiga Sass. $grid-columnse fa'aaogaina e fa'atupu ai le lautele (i le pasene) o koluma ta'itasi a'o $grid-gutter-widthfa'atulaga le lautele mo alavai o koluma.

$grid-columns: 12 !default;

Fa'asologa o laina

O le aga'i atu i tua atu o koluma lava latou, e mafai fo'i ona e fa'avasegaina le numera o fa'asologa fa'asologa. Afai e te mana'o na'o le fa laina fa'asologa, e te fa'afouina le $grid-breakpointsma $container-max-widthsi se mea fa'apenei:

A fai so'o se suiga i le Sass fesuia'i po'o fa'afanua, e tatau ona e fa'asaoina au suiga ma toe fa'aopoopo. O le faia o lea mea o le a maua ai se seti fou o vasega fa'avasega fa'asologa mo le lautele o koluma, fa'asili, ma le fa'atonuga. O le a fa'afouina fo'i mea faigaluega fa'aalia e tali atu e fa'aoga ai fa'aputuga masani. Ia mautinoa e seti fa'asologa fa'atatau ile px(e le rem, em, po'o le %).
