Grid system

Gwiritsani ntchito gridi yathu yamphamvu yoyambira flexbox kuti mupange masanjidwe amitundu yonse ndi makulidwe ake chifukwa cha magawo khumi ndi awiri, magawo asanu omvera osakhazikika, zosinthika za Sass ndi zosakaniza, ndi makalasi ambiri omwe adafotokozedwatu.

Momwe zimagwirira ntchito

Dongosolo la grid ya Bootstrap limagwiritsa ntchito zotengera zingapo, mizere, ndi mizere kuti isanjidwe ndikugwirizanitsa zomwe zili. Imapangidwa ndi flexbox ndipo imayankha kwathunthu. Pansipa pali chitsanzo ndi kuyang'ana mozama momwe gululi limakhalira pamodzi.

Chitsanzo chapamwambachi chimapanga mizati itatu yofanana m'lifupi pazida zazing'ono, zapakati, zazikulu, ndi zazikulu zowonjezera pogwiritsa ntchito makalasi athu omwe tawafotokozeratu. Mizati imeneyo ili pakati pa tsamba ndi kholo .container.

Kuyiphwanya, nayi momwe imagwirira ntchito:

Zotengera zimakupatsirani njira yokhazikitsira pakati ndikuwongolera mopingasa zomwe zili patsamba lanu. Gwiritsani ntchito kukula kwa .containerpixel komvera kapena pamawonekedwe onse ndi makulidwe a chipangizo..container-fluidwidth: 100%
Mizere ndi zokutira pamizere. Chigawo chilichonse chili ndi chopingasa padding(chotchedwa gutter) chowongolera danga pakati pawo. Izi paddingndiye zimatsutsidwa pamizere yokhala ndi malire olakwika. Mwanjira iyi, zonse zomwe zili m'mipingo yanu zimayang'aniridwa kumanzere.
Pamasanjidwe a gridi, zomwe zili mumizere ziyenera kuyikidwa m'mizere ndipo magawo okhawo omwe angakhale ana amizere.
Chifukwa cha flexbox, mizati ya gridi popanda kutchulidwa widthimangokhazikitsidwa ngati mizere yofanana m'lifupi. Mwachitsanzo, magawo anayi amtundu .col-smuliwonse adzakhala 25% m'lifupi kuchokera pagawo laling'ono kupita mmwamba. Onani gawo lazopanga zokha kuti mupeze zitsanzo zambiri.
Makalasi amizere amawonetsa kuchuluka kwa magawo omwe mukufuna kugwiritsa ntchito pa 12 pa mzere uliwonse. Chifukwa chake, ngati mukufuna mizati itatu yopingasa yofanana, mutha kugwiritsa ntchito .col-4.
Mizati widths imayikidwa muzochulukira, kotero nthawi zonse imakhala yamadzimadzi komanso yokulirapo poyerekeza ndi gawo la makolo awo.
Mizati imakhala yopingasa paddingkuti ipange ngalande pakati pa mizati payokha, komabe, mutha kuchotsa marginmizere ndi mizere paddingyokhala .no-guttersndi .row.
Kuti gululi liziyankha, pali zodulitsa ma gridi asanu, imodzi pagawo lililonse loyankhidwa : ma breakpoints onse (owonjezera ang'onoang'ono), ang'onoang'ono, apakatikati, akulu, ndi akulu owonjezera.
Kudumpha kwa ma gridi kumatengera mafunso ochepera a m'lifupi mwake, kutanthauza kuti amagwira ntchito pagawo limodzi ndi onse omwe ali pamwamba pake (mwachitsanzo, .col-sm-4zimagwira ntchito pazida zazing'ono, zapakati, zazikulu, ndi zazikulu, koma osati poyambira xs).
Mutha kugwiritsa ntchito makalasi a gridi omwe afotokozedwatu (monga .col-4) kapena zosakaniza za Sass kuti musinthe mawonekedwe.

Dziwani zoperewera ndi nsikidzi kuzungulira flexbox , monga kulephera kugwiritsa ntchito zinthu zina za HTML ngati zotengera zosinthika .

Zosankha zamagulu

Pomwe Bootstrap imagwiritsa ntchito ems kapena rems kutanthauzira makulidwe ambiri, pxs amagwiritsidwa ntchito podulira ma gridi ndi m'lifupi mwake. Izi zili choncho chifukwa m'lifupi mwake malo owonera ndi ma pixel ndipo sasintha ndi kukula kwa mawonekedwe .

Onani momwe ma gridi a Bootstrap amagwirira ntchito pazida zingapo zokhala ndi tebulo lothandizira.

Zopanga zokha mizati

Gwiritsani ntchito makalasi a magawo enieni a magawo kuti musinthe magawo mosavuta popanda kalasi yodziwika bwino ngati .col-sm-6.

Kufanana m'lifupi

Mwachitsanzo, apa pali mitundu iwiri ya gridi yomwe imagwira ntchito pa chipangizo chilichonse ndi malo owonera, kuyambira xsmpaka xl. Onjezani kuchuluka kwa makalasi opanda ma unit pagawo lililonse lomwe mungafune ndipo gawo lililonse likhala lofanana m'lifupi.
