Li-breakpoints tse arabelang

Kaha Bootstrap e ntlafalitsoe hore e be selefouno pele, re sebelisa lipotso tse seng kae tsa mecha ea litaba ho theha likheo tse utloahalang bakeng sa meralo le lihokelo tsa rona. Hangata li-breakpoints tsena li ipapisitse le bophara ba bonyane ba sebaka sa pono, 'me li re lumella ho phahamisa likarolo ha sebaka sa pono se fetoha.

Bootstrap haholo-holo e sebelisa mefuta e latelang ea lipotso tsa mecha ea litaba-kapa li-breakpoints-mohloling oa rona oa lifaele tsa Sass bakeng sa sebopeho sa rona, tsamaiso ea grid, le likaroloana.

// Extra small devices (portrait phones, less than 576px)
// No media query 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) { ... }

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

Kaha re ngola mohloli oa rona oa CSS ho Sass, lipotso tsohle tsa rona tsa media li fumaneha ka li-mixins tsa Sass:

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

// Example usage:
@include media-breakpoint-up(sm) {
  .some-class {
    display: block;
  }
}

Ka linako tse ling re sebelisa lipotso tsa media tse eang lehlakoreng le leng (saese e fanoeng skrineng kapa e nyane ):

// Extra 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) { ... }

// Extra large devices (large desktops)
// No media query since the extra-large breakpoint has no upper bound on its width

Hape, lipotso tsena tsa media li fumaneha hape ka li-mixins tsa Sass:

@include media-breakpoint-down(xs) { ... }
@include media-breakpoint-down(sm) { ... }
@include media-breakpoint-down(md) { ... }
@include media-breakpoint-down(lg) { ... }

Ho boetse ho na le lipotso tsa mecha ea litaba le li-mixins bakeng sa ho shebana le karolo e le 'ngoe ea boholo ba skrine ho sebelisa bonyane le bophara bo phahameng ka ho fetisisa.

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

// Small devices (landscape phones, 576px and up)
@media (min-width: 576px) and (max-width: 767.98px) { ... }

// Medium devices (tablets, 768px and up)
@media (min-width: 768px) and (max-width: 991.98px) { ... }

// Large devices (desktops, 992px and up)
@media (min-width: 992px) and (max-width: 1199.98px) { ... }

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

Lipotso tsena tsa media li fumaneha hape ka li-mixins tsa Sass:

@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) { ... }

Ka mokhoa o ts'oanang, lipotso tsa media li ka akaretsa bophara ba libaka tse ngata:

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

Motsoako oa Sass bakeng sa ho shebana le boholo bo lekanang ba skrine e ka ba:

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

Z-index

Likarolo tse 'maloa tsa Bootstrap li sebelisa z-index, thepa ea CSS e thusang ho laola sebopeho ka ho fana ka axis ea boraro ho hlophisa litaba.
