Pūnaehana mānoanoa

E hoʻohana i kā mākou pahu flexbox mobile-first ikaika e kūkulu i nā hoʻolālā o nā ʻano a me nā nui āpau e mahalo i kahi ʻōnaehana kolamu ʻumikūmālua, ʻelima mau pae pane pane paʻamau, Sass variables and mixins, a me ka nui o nā papa i koho mua ʻia.

Pehea e hana ai

Hoʻohana ka ʻōnaehana mākia ʻo Bootstrap i kahi pūʻulu o nā ipu, nā lālani, a me nā kolamu e hoʻonohonoho a hoʻopololei i ka ʻike. Ua kūkulu ʻia me ka flexbox a pane piha. Aia ma lalo kahi laʻana a me kahi nānā hohonu i ke ʻano o ka hui ʻana o ka pā.

He mea hou a ʻike ʻole paha me ka flexbox? E heluhelu i kēia CSS Tricks flexbox alakaʻi no ka hope, terminology, alakaʻi, a me nā snippet code.

ʻO kekahi o nā kolamu ʻekolu

<div class="container">
  <div class="row">
    <div class="col-sm">
      One of three columns
    </div>
    <div class="col-sm">
      One of three columns
    </div>
    <div class="col-sm">
      One of three columns
    </div>
  </div>
</div>

Hoʻokumu ka laʻana i luna i ʻekolu kolamu like-ākea ma nā mea liʻiliʻi, waena, nui, a ʻoi aku ka nui me ka hoʻohana ʻana i kā mākou papa kuhikuhi mua. Aia kēlā mau kolamu ma ka ʻaoʻao me ka makua .container.

ʻO ka wehe ʻana i lalo, eia ke ʻano o ka hana ʻana:

Hāʻawi nā pahu i kahi ala e hoʻokaʻawale a hoʻopaʻa i nā ʻike o kāu pūnaewele. E hoʻohana .containerno ka laula pika pane a .container-fluidi ʻole width: 100%ma nā ʻaoʻao āpau a me ka nui o nā hāmeʻa.
ʻO nā lālani nā mea ʻōwili no nā kolamu. He paepae ko kēlā me kēia kolamu padding(i kapa ʻia he auwai) no ka mālama ʻana i ka hakahaka ma waena o lākou. Hoʻopaʻa ʻia kēia paddingma nā lālani me nā palena ʻino. Ma kēia ala, ʻike maka ʻia nā ʻike a pau o kāu mau kolamu ma ka ʻaoʻao hema.
Ma kahi hoʻolālā mānoanoa, pono e waiho ʻia ka ʻike ma loko o nā kolamu a ʻo nā kolamu wale nō paha nā keiki o nā lālani.
Mahalo iā flexbox, e hoʻonohonoho ʻokoʻa nā kolamu me ka ʻole o kahi kikoʻī widthe like me nā kolamu ākea like. No ka laʻana, ʻehā mau manawa o .col-smkēlā me kēia me 25% ākea mai ka wahi haʻi liʻiliʻi a piʻi. E ʻike i ka ʻāpana kolamu hoʻonohonoho ʻokoʻa no nā laʻana hou aku.
Hōʻike nā papa kolamu i ka helu o nā kolamu āu e makemake ai e hoʻohana mai ka 12 hiki i kēlā me kēia lālani. No laila, inā makemake ʻoe i ʻekolu kolamu like-ākea ma waena, hiki iā ʻoe ke hoʻohana .col-4.
Hoʻonohonoho widthʻia nā kolamu i nā pākēneka, no laila e maʻa mau lākou a me ka nui e pili ana i ko lākou ʻano makua.
Loaʻa i nā kolamu ka pae ākea paddinge hana i nā auwai ma waena o kēlā me kēia kolamu, akā naʻe, hiki iā ʻoe ke wehe i ka marginlaina mai nā lālani a paddingmai nā kolamu me .no-gutterska .row.
No ka pane ʻana i ka mānoanoa, ʻelima mau wahi haʻihaʻi, hoʻokahi no kēlā me kēia haʻihaʻi pane : nā haʻi āpau (ʻoi aku ka liʻiliʻi), liʻiliʻi, waena, nui, a ʻoi aku ka nui.
Hoʻokumu ʻia nā wahi haʻihaʻi ma luna o nā nīnau media laula liʻiliʻi, ʻo ia hoʻi , pili lākou i kēlā wahi haʻihaʻi a me nā mea a pau ma luna o ia (e laʻa, .col-sm-4pili i nā mea liʻiliʻi, waena, nui, a me nā mea nui ʻē aʻe, ʻaʻole naʻe ka xshaki mua).
Hiki iā ʻoe ke hoʻohana i nā papa mākia i koho mua ʻia (e like me .col-4) a i ʻole nā hui Sass no ka hōʻailona semantic hou aʻe.

E makaʻala i nā palena a me nā ʻino e pili ana i ka flexbox , e like me ka hiki ʻole ke hoʻohana i kekahi mau mea HTML ma ke ʻano he pahu flex .

Nā koho koho

ʻOiai e hoʻohana ana ʻo Bootstrap i nā ems a i ʻole rems no ka wehewehe ʻana i ka nui o ka nui, pxhoʻohana ʻia ʻo s no nā wahi haki a me nā laula ipu. ʻO kēia no ka mea aia ka laulā viewport i nā pika a ʻaʻole loli me ka nui font .

E ʻike pehea e hana ai nā hiʻohiʻona o ka ʻōnaehana mākia Bootstrap ma nā ʻaoʻao he nui me kahi papaʻaina.

	ʻOi aku ka liʻiliʻi <576px	≥576px liʻiliʻi	≥768 px	Nui ≥992px	Nui nui ≥1200px
Ka laula o ka ipu nui	ʻAʻohe (aunoa)	540px	720px	960px	1140px

# o nā kolamu	12
Laulā ʻauwai	30px (15px ma kēlā me kēia ʻaoʻao o kahi kolamu)
Nestable	ʻAe
Kakau ʻana o ke kolamu	ʻAe

Nā kolamu hoʻonohonoho ʻakomi

E hoʻohana i nā papa kolamu breakpoint-specific no ka maʻalahi o ka nui kolamu me ka ʻole o ka papa helu kikoʻī e like me .col-sm-6.

Kaulike-ākea

Eia kekahi laʻana, eia nā papa kuhikuhi ʻelua e pili ana i kēlā me kēia hāmeʻa a me ka viewport, mai xska xl. E hoʻohui i kekahi helu o nā papa ʻāpana liʻiliʻi no kēlā me kēia haʻihaʻi āu e pono ai a ʻo kēlā me kēia kolamu e like ka laulā.

Ke hoʻohana nei i nā faila Sass kumu o Bootstrap, loaʻa iā ʻoe ke koho o ka hoʻohana ʻana i nā ʻano Sass a me nā mixins e hana i nā ʻaoʻao maʻamau, semantic, a me ka pane pane. Ke hoʻohana nei kā mākou papa papa kuhikuhi i kēia mau ʻano like ʻole a me nā mixins e hāʻawi i kahi papa holoʻokoʻa o nā papa mākaukau no ka hoʻolālā pane wikiwiki.

Nā mea hoʻololi

Ho'oholo nā mea ho'ololi a me nā palapala 'āina i ka heluna o nā kolamu, ka laula o ka 'auwaha, a me ka wahi nīnau media kahi e ho'omaka ai nā kolamu lana. Hoʻohana mākou i kēia no ka hoʻopuka ʻana i nā papa papa kuhikuhi i hoʻopaʻa ʻia ma luna, a me nā mixins maʻamau i helu ʻia ma lalo nei.

Mea huikau

Hoʻohana pū ʻia nā mixins me nā mea hoʻololi grid e hoʻohua i ka CSS semantic no nā kolamu pahu pākahi.

// Creates a wrapper for a series of columns
@include make-row();

// Make the element grid-ready (applying everything but the width)
@include make-col-ready();
@include make-col($size, $columns: $grid-columns);

// Get fancy by offsetting, or changing the sort order
@include make-col-offset($size, $columns: $grid-columns);

Laʻana hoʻohana

Hiki iā ʻoe ke hoʻololi i nā mea hoʻololi i kāu mau waiwai maʻamau, a i ʻole e hoʻohana wale i nā mixins me kā lākou mau waiwai paʻamau. Eia kekahi laʻana o ka hoʻohana ʻana i nā hoʻonohonoho paʻamau no ka hana ʻana i kahi hoʻolālā ʻelua kolamu me kahi kaawale ma waena.

Hoʻopilikino i ka mānoanoa

Me ka hoʻohana ʻana i kā mākou mākia i kūkulu ʻia i nā ʻano Sass a me nā palapala ʻāina, hiki ke hoʻopilikino piha i nā papa grid i koho mua ʻia. E hoʻololi i ka helu o nā pae, ka nui o ka nīnau noiʻi media, a me ka laula ipu—a laila e hoʻohui hou.

Nā kolamu a me nā auwai

Hiki ke hoʻololi ʻia ka heluna o nā kolamu ma o nā ʻano hoʻololi Sass. $grid-columnshoʻohana ʻia e hana i nā laula (ma ka pākēneka) o kēlā me kēia kolamu me ka $grid-gutter-widthhoʻonohonoho ʻana i ka laula no nā auwai kolamu.

$grid-columns: 12 !default;
$grid-gutter-width: 30px !default;

Nā pae mānoanoa

Ke neʻe nei ma waho o nā kolamu ponoʻī, hiki iā ʻoe ke hoʻopilikino i ka helu o nā pae mānoanoa. Inā makemake ʻoe i ʻehā mau pae mānoanoa, e hoʻonui ʻoe i ka $grid-breakpointsa $container-max-widthsi kekahi mea e like me kēia:

$grid-breakpoints: (
  xs: 0,
  sm: 480px,
  md: 768px,
  lg: 1024px
);

$container-max-widths: (
  sm: 420px,
  md: 720px,
  lg: 960px
);

Ke hoʻololi nei i nā ʻano hoʻololi Sass a i ʻole palapala ʻāina, pono ʻoe e mālama i kāu mau hoʻololi a hoʻohui hou. Ma ka hana ʻana pēlā e hoʻopuka ai i kahi pūʻulu hou o nā papa mākia i koho mua ʻia no ka laulā kolamu, offset, a me ke kauoha. E hoʻonui hou ʻia nā pono hana ʻike pane no ka hoʻohana ʻana i nā wahi haʻi maʻamau. E hōʻoia i ka hoʻonohonoho ʻana i nā waiwai mākia i px(ʻaʻole rem, em, a i ʻole %).
