Kiki ekirimu?

Nga ekyongereza kya CSS, LESS erimu enkyukakyuka, mixins ez’ebitundutundu bya koodi ebiddamu okukozesebwa, emirimu gy’okubala okwangu, okuteeka ebisu, n’emirimu gya langi.

Manya ebisingawo

Kyalira omukutu omutongole ku http://lesscss.org/ okumanya ebisingawo.

Enkyukakyuka ezikyukakyuka

Okuddukanya langi n’emiwendo gya pixel mu CSS kiyinza okuluma akatono, ebiseera ebisinga nga kijjudde okukoppa n’okuteeka. Si ne LESS wadde —gaba langi oba emiwendo gya pixel nga enkyukakyuka era ozikyuse omulundi gumu.

Ebirungo ebitabuddwa

Ezo ssatu border-radius declarations olina okukola mu regular ol' CSS? Kati zikka ku layini emu nga ziyambibwako mixins, snippets za code z'osobola okuddamu okukozesa wonna.

Ebikwekweto

Fuula grid yo, okukulembera, n'okusinga super flexible nga okola math ku fly n'emirimu. Kubisaamu, gabana, gattako, era oggyeko ekkubo lyo erigenda ku CSS sanity.

Ebikwata ku mixins

Ebikozesebwa ebisookerwako (basic mixins).

Mixin enkulu mu bukulu ye include oba partial ku snippet ya CSS. Ziwandiikibwa nga kiraasi ya CSS era zisobola okuyitibwa wonna.

. elementi { .
  . okutereeza obulungi ();
} .

Ebikozesebwa mu kutabula (parametric mixins).

Parametric mixin eringa basic mixin, naye era ekkiriza parameters (wano we wava erinnya) n'emiwendo egy'enjawulo egy'okwesalirawo.

. elementi { .
  . ensalosalo - radius ( 4px );
} .

Kyangu okugattako ebibyo

Kumpi mixins zonna eza Bootstrap ziterekebwa mu mixins.less, fayiro ey’ekitalo ey’omugaso .less ekusobozesa okukozesa mixin mu fayiro yonna eya .less mu kitabo ky’ebikozesebwa.

Kale, genda mu maaso okozese ebiriwo oba wulira nga oli waddembe okugattako ebibyo nga bwe weetaaga.

Note: Bw'oba oweereza okusaba okusika ku GitHub ne CSS ekyusiddwa, olina okuddamu okukung'aanya CSS ng'oyita mu nkola yonna ku zino.

Ebikozesebwa mu kukungaanya

Node nga eriko makefile

Teeka omukung'aanya w'ennyiriri z'ekiragiro LESS ne uglify-js mu nsi yonna ne npm ng'okola ekiragiro kino wammanga:

$ npm okuteeka -g ekitono uglify-js

Bw'omala okussaako dduka budduka makeokuva ku kikolo kya bootstrap directory yo era mwenna muba otegese.

Okugatta ku ekyo, bw’oba olina watchr gy’ossaako, oyinza okudduka make watchokubeera ne bootstrap okuddamu okuzimbibwa mu ngeri ey’otoma buli lw’olongoosa fayiro mu bootstrap lib (kino tekikyetaagisa, nkola ya kukwanguyiza yokka).

Ennyiriri z’ekiragiro

Teeka ekintu kya LESS command line tool ng'oyita mu Node era okole ekiragiro kino wammanga:

$ lessc ./lib/okutandika.less > okutandika.css

Kakasa nti ossaamu --compressmu kiragiro ekyo bw'oba ogezaako okutereka bytes ezimu!

Javascript

Wano wefunire Less.js eyasembyeyo era oteekemu ekkubo erigenda mu yo (ne Bootstrap) mu <head>.

<link rel = "olupapula lw'omulembe/ekitono" href = "/ekkubo/okugenda/bootstrap.less" > <script src = "/ekkubo/okugenda/okutono.js" ></script>

Okuddamu okukung’aanya fayiro za .less, omala kuzitereka n’oddamu okutikka omuko gwo. Less.js ezikuŋŋaanya n’ezitereka mu kutereka okw’omu kitundu.

App etali ntongole eya Mac

App ya Mac etali ntongole etunuulira dayirekita za fayiro za .less era ekuŋŋaanya koodi mu fayiro z’omu kitundu oluvannyuma lwa buli kutereka fayiro ya .less etunuuliddwa.

Bw’oba oyagala, osobola okukyusakyusa by’oyagala mu app okusobola okukendeeza mu ngeri ey’otoma ne dayirekita ki fayiro ezikung’aanyiziddwa gye zikoma mu.
