Eget ratio

Utere flexo flexo mobili potenti nostro ad rationes omnium formarum et magnitudinum faciendarum per rationes duodecim columnarum, quinque gradibus respondentium default, variabilium Sass et mixinorum, ac justos classium praedefinitorum.

Quomodo facitur

Bootstrap ratio eget systematis utitur serie continentium, versuum et columnarum ad layout et align contentorum. Cum flexbox constructum est et plene responsivum est. Infra exemplum est et altissimam vide quomodo euismod coit.

Una trium columnarum

<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">

Exemplum superius tres columnas aequales latas in parvis, mediis, magnis, et extra grandes machinas utentes classibus eget praedefinitis nostris creat. Columnae istae in pagina cum parente centae sunt .container.

Solvendo, hic quomodo agit;

Vasa media praebent ad centrum ac transversatim codex tui situs contenta. Utere .containerad pixelam responsivam latitudinem vel .container-fluidper width: 100%omnes magnitudinum prospectus et machinae.
Ordines columnarum involucri sunt. Quaelibet columna horizontalem padding(quae stillicidium vocant) ad spatium inter se moderandum habet. Hoc paddingest ergo in versibus negativis marginibus counteracted. Hoc modo omnia contenta in columnis tuis sinistrum latus uisum est aligned.
In eget arcu, contenti intra columnas collocari debent et tantum columnae immediatae esse possunt puerorum ordinum.
Gratias flexbox, columnas eget sine certa widthvoluntate sponte pones sicut columnas latitudines aequales. Exempli gratia: quattuor instantiae .col-smvoluntatis singulae sponte 25% latae erunt a parvo puncto et sursum. Vide sectionem columnarum auto- ponendam pluribus exemplis.
Columnae classes numerum columnarum indicantes ex 12 per versu possibili uti velis. Si ergo tres columnas aequales latas vis transversas , uti potes .col-4.
Columnae widths in percentages collocatae sunt, ergo semper fluidi sunt et ad elementum parentis sui mediocri.
Columnae horizontales inter singulas columnas canales creare possunt, tamen a ordinibus et a columnis cum super paddingamoveri potes .marginpadding.no-gutters.row
Ad craticulam responsurum, quinque fracturae craticulae sunt, una pro unaquaque fractura responsiva : omnes fracturae (extra minima), parva, media, magna et extra magnum.
Grid puncta puncta in mediis quaestionibus minimae latitudinis fundantur, significantes unum punctum et omnes superiores (eg, .col-sm-4parvis, mediis, magnis, et extra grandes machinas, non autem primum xspunctum) applicant.
Potes uti praedefinitis eget classibus (similis .col-4) vel mixins Sass pro charactere plus semantico.

Animadverte limitationes et cimices circa flexboxs , sicut non posse uti aliqua HTML elementa sicut vascula flexiva .

Eget optiones

Dum Bootstrap utitur ems vel rems ad definiendas amplissimas magnitudinum, pxs adhibentur ad fracturae puncta et latitudines continens. Hoc est quod latitudo prospecti elementa inest et cum magnitudine fontis non mutat .

Vide quomodo aspectus Bootstrap eget systematis per multiplices machinis cum manu manus habilis laborant.

	Extra parva <576px	Parvus ≥576px	Medium ≥768px	Magnae ≥992px	Extra magnum ≥1200px
Max continens latitudo	Nemo (auto)	540px	720px	960px	1140px
Classis praepositionis	`.col-`	`.col-sm-`	`.col-md-`	`.col-lg-`	`.col-xl-`
# Columnarum	12
Tetigisset domatum fistulas latitudo	30px (15px in utraque parte columnae)
Nestable	Ita
Columna ordinatio	Ita

Auto-layout columnas

Utere ad breakpoint-specificae columnae classes ad faciliorem columnam inspectionem sine classe explicata numero similia .col-sm-6.

aequalis latitudo

Exempli gratia, hic duo proposita eget arcu quae ad omnem fabricam et conspectum pertinent, ab xsad xl. Adde quotlibet unitates-minores classes pro singulis ruptionibus quibus indigetis et cuiuslibet columnae latitudo eadem erit.

Columnae aequalis-latitudines in plures lineas frangi possunt, sed flexo safari cimex erat , qui hoc impediret quin operaretur sine explicatione flex-basisvel border. Versiones navigandi antiquiores operas sunt, sed necessariae non sunt si nunc hodie es.

Columna erumpit

Columnas fractis ad lineam novam in flexbox parvam hack requirit: elementum adde cum width: 100%quocunque columnas tuas ad novam lineam involvere vis. Communiter hoc fit cum multiplex .rows, sed non omnis modus exsecutionis huius rationem reddere potest.

Offsetting columnas

Vos can offsets eget columnas in duobus modis: nostri responsive .offset-grid classes et utilitates nostrae marginis . Eget classes magnitudines ad columnas aequant, margines magis utiles sunt ad propositum velox ubi latitudo cinguli variabilis est.

Offset classes

Movere columnas ad dextram utendi .offset-md-*classes. Haec genera columnae marginem sinistrum augent *. Nam .offset-md-4movet .col-md-4quattuor columnas.

Sass mixins

Cum per Bootstrap fontem Sass lima, optionem habes utendi Sass variabilium et mixins ut consuetudo, semantica, et responsiva paginae layout. Classes nostrae praedefinitae eget in eisdem differentiis et mixinis utantur ut integram classem paratarum ad usum generum praebeant ad propositum responsurum celeriter.

Variabilium

Variabiles et mappae numerum columnarum, triviis latitudinem determinant, et punctum instrumentorum quaesitum, quo in columnas volitare incipiant. His utimur ad generandum praedefinitas eget classes supra confirmatas, necnon pro consuetudine mixins infra recensita.

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

$grid-breakpoints: (
  // Extra small screen / phone
  xs: 0,
  // Small screen / phone

);

$container-max-widths: (
  sm: 540px,
  md: 720px,
  lg: 960px,
  xl: 1140px
);

Mixins

Mixins in conjunctione cum variabilium eget ad generandum semanticam CSS pro singulis columnis eget.

// 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);

Exemplum usus

Mutationes variabiles ad valorum suorum consuetudinum mutare potes, vel mixinis cum eorum defectu valoribus tantum utere. Exemplum est hic usus occasus defectus ad efficiendum duas columnas extensiones cum interstitio.

.example-container {
  width: 800px;
  @include make-container();
}

.example-row {

Customising malesuada euismod

Utendo nostro constructo in eget Sass variabilium et in mappis, potest omnino mos praefinitas classes eget. Mutare numerum linearum, instrumentorum dimensionum interrogationum, et latitudines continens continens, deinde recompile.

Columnae et tetigisset domatum fistulas

Numerus columnarum malesuada euismod mutari potest per variabiles Sass. $grid-columnsest generare latitudines uniuscuiusque columnae, dum $grid-gutter-widthlatitudinem ponit pro canalibus columnae.

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

Eget versus

Ultra ipsas columnas movens, etiam numerum ordinum euismod mos esto. Si quattuor tantum ordines egetis esses, renovare velis $grid-breakpointset $container-max-widthsad aliquid simile:

$grid-breakpoints: (
