21x9

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

Hi xikombiso, ku endla mpimo wa xivumbeko xa 2x1, veka --bs-aspect-ratio: 50%eka .ratio.

2x1

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

Xihlawulekisi lexi xa CSS xi endla leswaku swi olova ku cinca mpimo wa xivumbeko ku tsemakanya tindhawu to wisa. Leswi landzelaka i 4x3 ku sungula, kambe swi cinca ku ya eka 2x1 ya ntolovelo eka ndhawu yo wisa ya le xikarhi.

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

4x3, kutani 2x1

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