Ole mea lea e faʻamalieina ai lau CSS, faʻaleleia le taimi faʻaliliu, ma maua ai se poto masani mo au tagata asiasi.

Avanoa breakpoints

O le Bootstrap e aofia ai le ono faaletonu, o nisi taimi e taʻua o faʻasologa faʻasologa , mo le faʻaleleia o le fausiaina. E mafai ona fa'avasegaina nei va'aiga pe afai o lo'o e fa'aogaina a matou faila faila Sass.

Sa filifilia vaega ta'itasi e u'u lelei ai atigipusa o lona lautele e ta'i 12. O va'aiga e fai ma sui o se vaega o le tele o masini masani ma le tele o le va'aiga—e le fa'atatau tonu i mea fa'aoga uma po'o masini. Nai lo lena, o laina e maua ai se faavae malosi ma tumau e fausia i luga mo toetoe lava o soʻo se masini.

O nei va'aiga e mafai ona fa'avasegaina e ala i le Sass—e te mauaina i se fa'afanua Sass i la matou _variables.scsssitaili.

$grid-breakpoints: (
  xs: 0,

Mo nisi faʻamatalaga ma faʻataʻitaʻiga i le auala e sui ai a matou faʻafanua Sass ma fesuiaiga, faʻamolemole vaʻai i le vaega Sass o le Grid pepa .

Fa'asalalauga fesili

Talu ai ona o le Bootstrap ua atiaʻe e avea muamua ma telefoni feaveaʻi, matou te faʻaogaina ni nai faʻamatalaga faʻasalalau e fai ai ni vaʻa maaleale mo a matou faʻatulagaga ma fesoʻotaʻiga. O nei vaeluaga e tele lava e fa'avae i luga ole la'ititi ole va'aiga lautele ma fa'ataga ai tatou e fa'asili elemene pe a suia le va'aiga.

Min-lautele

O lo'o fa'aaoga muamua e Bootstrap vaega o fesili fa'asalalau nei—po'o fa'amavaega—i la tatou fa'apogai faila Sass mo la tatou fa'atulagaina, faiga fa'asologa, ma vaega.

// Source mixins

// No media query necessary for xs breakpoint as it's effectively `@media (min-width: 0) { ... }`
@include media-breakpoint-up(sm) { ... }
@include media-breakpoint-up(md) { ... }
@include media-breakpoint-up(lg) { ... }
@include media-breakpoint-up(xl) { ... }
@include media-breakpoint-up(xxl) { ... }

// Usage

// Example: Hide starting at `min-width: 0`, and then show at the `sm` breakpoint
.custom-class {
  display: none;
}
@include media-breakpoint-up(sm) {
  .custom-class {
    display: block;
  }
}

O nei fa'afefiloi Sass e fa'aliliu i totonu o la tatou CSS tu'ufa'atasia e fa'aaoga ai tau fa'ailoa i totonu oa tatou suiga Sass. Faataitaiga:

// X-Small devices (portrait phones, less than 576px)
// No media query for `xs` since this is the default in Bootstrap

// Small devices (landscape phones, 576px and up)
@media (min-width: 576px) { ... }

// Medium devices (tablets, 768px and up)
@media (min-width: 768px) { ... }

// Large devices (desktops, 992px and up)
@media (min-width: 992px) { ... }

// X-Large devices (large desktops, 1200px and up)
@media (min-width: 1200px) { ... }

// XX-Large devices (larger desktops, 1400px and up)
@media (min-width: 1400px) { ... }

Max-lautele

Matou te faʻaogaina i nisi taimi fesili faʻasalalau e alu i le isi itu (le lapopoa o le lau pe laʻititi ):

// No media query necessary for xs breakpoint as it's effectively `@media (max-width: 0) { ... }`
@include media-breakpoint-down(sm) { ... }
@include media-breakpoint-down(md) { ... }
@include media-breakpoint-down(lg) { ... }
@include media-breakpoint-down(xl) { ... }
@include media-breakpoint-down(xxl) { ... }

// Example: Style from medium breakpoint and down
@include media-breakpoint-down(md) {
  .custom-class {
    display: block;
  }
}

O nei fa'afefiloi e ave na fa'aupuga va'aiga, toese .02pxmai ai, ma fa'aaoga e fai ma a tatou max-widthfa'atauga. Faataitaiga:

// X-Small devices (portrait phones, less than 576px)
@media (max-width: 575.98px) { ... }

// Small devices (landscape phones, less than 768px)
@media (max-width: 767.98px) { ... }

// Medium devices (tablets, less than 992px)
@media (max-width: 991.98px) { ... }

// Large devices (desktops, less than 1200px)
@media (max-width: 1199.98px) { ... }

// X-Large devices (large desktops, less than 1400px)
@media (max-width: 1399.98px) { ... }

// XX-Large devices (larger desktops)
// No media query since the xxl breakpoint has no upper bound on its width

Single breakpoint

There are also media queries and mixins for targeting a single segment of screen sizes using the minimum and maximum breakpoint widths.

@include media-breakpoint-only(xs) { ... }
@include media-breakpoint-only(sm) { ... }
@include media-breakpoint-only(md) { ... }
@include media-breakpoint-only(lg) { ... }
@include media-breakpoint-only(xl) { ... }
@include media-breakpoint-only(xxl) { ... }

For example the @include media-breakpoint-only(md) { ... } will result in :

@media (min-width: 768px) and (max-width: 991.98px) { ... }

Between breakpoints

Similarly, media queries may span multiple breakpoint widths:

@include media-breakpoint-between(md, xl) { ... }

Which results in:

// Example
// Apply styles starting from medium devices and up to extra large devices
@media (min-width: 768px) and (max-width: 1199.98px) { ... }
