Di ɛgzampul we de ɔp de mek tri ikwal-wid kɔlɔm dɛn pan smɔl, midul, big, ɛn ɛkstra big divays dɛn we de yuz wi grid klas dɛn we wi dɔn disayd fɔ du. Dɛn kɔlɔm dɛn de de na di sɛntrɔm na di pej wit di mama ɔ papa .container.

We yu brok am dɔŋ, na so i de wok:

Kɔntena dɛn de gi wan we fɔ sɛnt ɛn ɔrizɔntal pad di tin dɛn we de insay yu sayt. Yuz .containerfɔ wan piksɛl wid we de ansa ɔ .container-fluidfɔ width: 100%akɔdin to ɔl di viupɔt ɛn divays saiz dɛn.

Insay grid layout, kɔntinyu fɔ de insay kɔlɔm ɛn na kɔlɔm nɔmɔ kin bi pikin dɛn fɔ row dɛn wantɛm wantɛm.
Tɛnki fɔ flexbox, grid kɔlɔm dɛn we nɔ gɛt wan spɛsifikɛd widthgo ɔtomɛtik layout as ikwal wit kɔlɔm dɛn. Fɔ ɛgzampul, 4 instans dɛn fɔ .col-smgo ɔtomɛtik wan 25% waid frɔm di smɔl brekpɔynt ɛn ɔp. Si di ɔto-layout kɔlɔm dɛn sɛkshɔn fɔ no mɔ ɛgzampul dɛn.
Kɔlɔm klas dɛn de sho di nɔmba fɔ di kɔlɔm dɛn we yu go want fɔ yuz pan di 12 we pɔsibul fɔ ɛni row. So, if yu want tri kɔlɔm dɛn we gɛt ikwal-wid akɔdin, yu kin yuz .col-4.

Fɔ mek di grid ansa, fayv grid brek pɔynt dɛn de, wan fɔ ɛni brek pɔynt we de ansa : ɔl di brek pɔynt dɛn (ɛkstra smɔl), smɔl, midul, big, ɛn ɛkstra big.

Yu kin yuz prɛdifayn grid klas dɛn (lɛk .col-4) ɔ Sass miksin fɔ mɔ sɛmantik mak.
