Ukubukeka kwezilinganiso

Ukubukeka kwezilinganiso kungenziwa ngendlela oyifisayo ngamakilasi okulungisa. Ngokuzenzakalelayo amakilasi esilinganiso alandelayo anikeziwe:

1x1

4x3

16x9

21x9

<div class="ratio ratio-1x1">
  <div>1x1</div>
</div>
<div class="ratio ratio-4x3">
  <div>4x3</div>
</div>
<div class="ratio ratio-16x9">
  <div>16x9</div>
</div>
<div class="ratio ratio-21x9">
  <div>21x9</div>
</div>

Izilinganiso zangokwezifiso

Ikilasi ngalinye .ratio-*lifaka impahla yangokwezifiso ye-CSS (noma i-CSS variable) kusikhethi. Ungakwazi ukubhala ngaphezulu lokhu kuguquguquka kwe-CSS ukuze udale izilinganiso ze-aspect yangokwezifiso lapho undiza ngezibalo ezithile ezisheshayo ngasohlangothini lwakho.

Isibonelo, ukuze udale i-aspect ratio engu-2x1, setha --bs-aspect-ratio: 50%kokuthi .ratio.

2x1

<div class="ratio" style="--bs-aspect-ratio: 50%;">
  <div>2x1</div>
</div>

Lokhu okuguquguqukayo kwe-CSS kwenza kube lula ukulungisa ukubukeka kwesilinganiselo kuwo wonke ama-breakpoint. Okulandelayo yi-4x3 ukuqala, kodwa kushintshela ku-2x1 yangokwezifiso endaweni yokuphumula emaphakathi.

.ratio-4x3 {
  @include media-breakpoint-up(md) {
    --bs-aspect-ratio: 50%; // 2x1
  }
}

4x3, bese 2x1

<div class="ratio ratio-4x3">
  <div>4x3, then 2x1</div>
</div>
