Ke hoʻohana nei i ka LESS me Bootstrap
Hoʻopilikino a hoʻonui i ka Bootstrap me LESS , kahi CSS preprocessor, e hoʻohana pono i nā mea hoʻololi, hui pū, a me nā mea hou aʻe i hoʻohana ʻia e kūkulu i kā Bootstrap CSS.
Kūkulu ʻia me LESS
No ke aha e emi ai?
Hana ʻia ʻo Bootstrap me LESS ma kāna kumu, he ʻōlelo stylesheet ikaika i hana ʻia e kā mākou hoaaloha maikaʻi, ʻo Alexis Sellier . ʻOi aku ka wikiwiki, maʻalahi, a me ka leʻaleʻa o ka hoʻomohala ʻana i ka CSS e pili ana i nā ʻōnaehana.
He aha ka mea i komo?
Ma ke ʻano he hoʻonui ʻia o CSS, LESS nā mea hoʻololi, mixins no ka hoʻohana hou ʻana i nā snippets o ke code, nā hana no ka makemakika maʻalahi, nesting, a me nā hana kala.
Nā mea hoʻololi
ʻO ka mālama ʻana i nā waihoʻoluʻu a me nā waiwai pixel ma CSS hiki ke lilo i mea ʻeha, maʻamau piha i ke kope a paʻi. ʻAʻole me LESS akā naʻe-e hoʻokaʻawale i nā kala a i ʻole nā waiwai pixel e like me nā loli a hoʻololi iā lākou i hoʻokahi manawa.
Mea huikau
ʻO kēlā mau ʻōlelo hoʻolaha palena palena ʻekolu āu e pono ai e hana ma ka CSS maʻamau? I kēia manawa aia lākou i ka laina hoʻokahi me ke kōkua o mixins, snippets of code hiki iā ʻoe ke hoʻohana hou i nā wahi āpau.
Nā hana
Hana i kāu mākia, alakaʻi, a ʻoi aku ka maʻalahi ma ka hana ʻana i ka makemakika ma ka lele me nā hana. E hoʻonui, e puʻunaue, e hoʻohui, a e unuhi i kou ala i ka CSS sanity.
Nā mea hoʻololi Bootstrap Nā ʻano liʻiliʻi liʻiliʻi, ko lākou mau waiwai, a me nā alakaʻi hoʻohana

Hoʻohui maʻalahi iā ʻoe iho
Ma kahi kokoke i nā hui hui ʻo Bootstrap e mālama ʻia i mixins.less, kahi faila .less maikaʻi e hiki ai iā ʻoe ke hoʻohana i kahi mixin i kekahi o nā faila .less i loko o ka pahu hana.
No laila, e hele a hoʻohana i nā mea i loaʻa a i ʻole e ʻoluʻolu e hoʻohui i kāu ponoʻī e like me kou makemake.

Hoʻopili ʻana i ka Bootstrap me LESS
Nā mea hana no ka hōʻuluʻulu ʻana
Node me makefile
E hoʻouka i ka LESS command line compiler a uglify-js ma ka honua holoʻokoʻa me npm ma ka holo ʻana i kēia kauoha:
$ npm hoʻokomo -g liʻiliʻi uglify-js
Ke hoʻokomo ʻia e holo wale makemai ke kumu o kāu papa kuhikuhi bootstrap a ua mākaukau ʻoe.
Eia hou, inā ua hoʻokomo ʻia ʻo watchr , hiki iā ʻoe ke holo make watche hana hou i ka bootstrap i kēlā me kēia manawa āu e hoʻoponopono ai i kahi faila ma ka bootstrap lib (ʻaʻole koi ʻia kēia, he ala maʻalahi wale nō).
Laina kauoha
E hoʻouka i ka mea hana laina kauoha LESS ma o Node a holo i kēia kauoha:
$ lessc ./lib/bootstrap.less > bootstrap.css
E hoʻokomo --compressi loko o kēlā kauoha inā ʻoe e hoʻāʻo e mālama i kekahi mau bytes!
Javascript
Hoʻoiho i ka Less.js hou loa a hoʻokomo i ke ala i laila (a me Bootstrap) i ka <head>.
<link rel = "stylesheet/less" href = "/path/to/bootstrap.less" > <script src = "/path/to/less.js" ></script>
No ka hōʻuluʻulu hou ʻana i nā faila .less, mālama wale iā lākou a hoʻouka hou i kāu ʻaoʻao. Hoʻopili ʻo Less.js iā lākou a mālama iā lākou i loko o kahi waihona kūloko.
ʻO ka polokalamu Mac kūhelu ʻole
Nānā ka polokalamu Mac manaʻole i nā papa kuhikuhi o nā faila .less a hōʻuluʻulu i ke code i nā faila kūloko ma hope o kēlā me kēia mālama ʻana o kahi faila .less i nānā ʻia.
Inā makemake ʻoe, hiki iā ʻoe ke hoʻololi i nā makemake i ka app no ka hoʻohaʻahaʻa maʻalahi a me ka papa kuhikuhi i hoʻopau ʻia nā faila i hoʻopili ʻia.
Nā polokalamu Mac hou aku
Crunch
ʻO Crunch kahi mea hoʻoponopono LESS maikaʻi a me ka mea hoʻopili i kūkulu ʻia ma Adobe Air.
CodeKit
Hoʻokumu ʻia e ke kanaka like me ka polokalamu Mac manaʻo ʻole, CodeKit he polokalamu Mac e hōʻuluʻulu ana i LESS, SASS, Stylus, a me CoffeeScript.
maʻalahi
ʻO Mac, Linux, a me ka polokalamu PC no ka huki ʻana a me ka hoʻokuʻu ʻana i nā faila LESS. Eia kekahi, aia ke code kumu ma GitHub .
