Imilinganiselo
Sebenzisa i-pseudo elements ezenziweyo ukwenza i-elementi igcine umlinganiselo wokhetho lwakho. Ifanelekile ukuphatha ividiyo okanye umboniso wesilayidi ngokusekwe kububanzi bomzali.
Malunga
Sebenzisa umncedisi wokulinganisa ukulawula umlinganiselo womxholo womxholo wangaphandle njengo <iframe>
s, <embed>
s, <video>
s, kunye no <object>
s. Aba bancedisi nabo banokusetyenziswa kuyo nayiphi na into eqhelekileyo ye-HTML yomntwana (umzekelo, a <div>
okanye <img>
). Izimbo zisetyenziswa ukusuka .ratio
kwiklasi yabazali ukuya ngqo emntwaneni.
Aspect ratios ibhengezwe kwimaphu ye-Sass kwaye ibandakanywe kwiklasi nganye ngokuguquguquka kwe-CSS, ekwavumela umlinganiselo wenkalo eqhelekileyo .

Umzekelo
Songa naluphi na uzinziso, njenge <iframe>
, kwisiqalelo somzali kunye .ratio
neklasi yomlinganiselo. Isiqalelo somntwana esikhawulezileyo senziwa ubungakanani ngokuzenzekela enkosi kumkhethi wethu jikelele .ratio > *
.
<div class="ratio ratio-16x9">

</div>
Aspect ratios
Umyinge womlinganiselo unokwenziwa ngokweeklasi zesilungisi. Ngokungagqibekanga kubonelelwe ngezi klasi zilandelayo:
<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>
Ulungelelwaniso oluqhelekileyo
Iklasi nganye .ratio-*
ibandakanya ipropati yesiko le-CSS (okanye i-CSS variable) kumkhethi. Ungayibhala ngaphezulu le CSS iguquguqukayo ukwenza ulungelelwaniso lwenkalo yesiko kubhabho ngezibalo ezikhawulezayo kwicala lakho.
Ngokomzekelo, ukwenza umlinganiselo we-2x1, usethe --bs-aspect-ratio: 50%
kwi- .ratio
.
<div class="ratio" style="--bs-aspect-ratio: 50%;">
<div>2x1</div>
</div>
Oku kuguquguquka kwe-CSS kwenza kube lula ukulungisa umlinganiselo wembonakalo kuzo zonke iindawo zokuqhawula. Oku kulandelayo yi-4x3 ukuqala, kodwa utshintsho kwi-2x1 yesiko kwinqanaba eliphakathi.
.ratio-4x3 {
@include media-breakpoint-up(md) {
--bs-aspect-ratio: 50%; // 2x1
}
}
<div class="ratio ratio-4x3">
<div>4x3, then 2x1</div>
</div>
Sass imephu
Ngaphakathi _variables.scss
, ungatshintsha umlinganiselo wembonakalo ofuna ukuyisebenzisa. $ratio-aspect-ratios
Nantsi imephu yethu ehlala ikho . Guqula imephu ngendlela othanda ngayo kwaye uqokelele iSass yakho ukuze uyisebenzise.
$aspect-ratios: (
"1x1": 100%,
"4x3": calc(3 / 4 * 100%),
"16x9": calc(9 / 16 * 100%),
"21x9": calc(9 / 21 * 100%)
);
