A'oa'o pe fa'afefea ona sui koluma ma ni nai filifiliga mo le fa'aogaina, fa'atonu, ma le fa'asili fa'afetai i la matou flexbox grid system. Ma le isi, va'ai pe fa'apefea ona fa'aogaina vasega koluma e fa'atautaia ai le lautele o elemene e le o fa'a'ala.

I luga o lenei itulau

Ulu i luga! Ia mautinoa e faitau muamua le itulau Grid a'o le'i su'esu'e pe fa'afefea ona sui ma fa'avasega au koluma fa'asologa.

E faapefea ona latou galulue

O koluma e fausia i luga o le fausaga o flexbox. Flexbox o lona uiga e iai a matou filifiliga mo le suia o koluma taʻitasi ma faʻaleleia vaega o koluma i le laina tulaga . E te filifili pe fa'afefea ona tupu, fa'aiti'i, pe suia fo'i koluma.
Pe a fauina fa'asologa o fa'asologa, o mea uma e alu i koluma. O le fa'asologa o le fa'asologa o Bootstrap e alu mai lea atigipusa i lea laina i lea koluma i au mea. I taimi e le masani ai, e mafai ona e tuʻufaʻatasia anotusi ma koluma, ae ia nofouta e mafai ona i ai ni taunuuga e leʻi mafaufauina.
O le Bootstrap e aofia ai vasega faʻatulagaina mo le fatuina o faʻatulagaga vave, tali. Faatasi ai ma le ono motumotu ma le sefulu lua koluma i laina taʻitasi, e tele a matou vasega ua uma ona fausia mo oe e fai ai au faʻatulagaga manaʻomia. E mafai ona fa'agata e ala i Sass pe a e mana'o ai.

  <p>
    A paragraph of placeholder text. We're using it here to show the use of the clearfix class. We're adding quite a few meaningless phrases here to demonstrate how the columns interact here with the floated image.
  </p>

  <p>
    As you can see the paragraphs gracefully wrap around the floated image. Now imagine how this would look with some actual content in here, rather than just this boring placeholder text that goes on and on, but actually conveys no tangible information at. It simply takes up space and should not really be read.
  </p>

  <p>
    And yet, here you are, still persevering in reading this placeholder text, hoping for some more insights, or some hidden easter egg of content. A joke, perhaps. Unfortunately, there's none of that here.
