Opacità

Aggiuntu in v5.2.0

L'utilità Bootstrap border-{color}sò generate cù Sass cù variabili CSS. Questu permette cambiamenti di culore in tempu reale senza compilazione è cambiamenti dinamichi di trasparenza alfa.

Cumu travaglia

Cunsiderate a nostra .border-successutilità predeterminata.

.border-success {
  --bs-border-opacity: 1;
  border-color: rgba(var(--bs-success-rgb), var(--bs-border-opacity)) !important;
}

Utilizemu una versione RGB di a nostra --bs-success(cù u valore di 25, 135, 84) CSS variabile è aghjunghje una seconda variabile CSS, --bs-border-opacity, per a trasparenza alfa (cù un valore predeterminatu 1grazia à una variabile CSS locale). Questu significa chì ogni volta chì aduprate avà, u vostru valore .border-successcalculatu hè . A variabile CSS locale in ogni classa evita i prublemi di eredità, cusì l'istanze nidificate di l'utilità ùn anu micca automaticamente una trasparenza alfa modificata.colorrgba(25, 135, 84, 1).border-*

Esempiu

Per cambià quella opacità, annullate --bs-border-opacityvia stili persunalizati o stili inline.

Questu hè u cunfini di successu predeterminatu
Questu hè u cunfini di successu di opacità di 50%.
html
<div class="border border-success p-2 mb-2">This is default success border</div>
<div class="border border-success p-2" style="--bs-border-opacity: .5;">This is 50% opacity success border</div>

Oppure, sceglite una di l' .border-opacityutilità:

Questu hè u cunfini di successu predeterminatu
Questu hè u cunfini di successu di opacità di 75%.
Questu hè u cunfini di successu di opacità di 50%.
Questu hè u cunfini di successu di opacità di 25%.
Questu hè u cunfini di successu di opacità di 10%.
html
<div class="border border-success p-2 mb-2">This is default success border</div>
<div class="border border-success p-2 mb-2 border-opacity-75">This is 75% opacity success border</div>
<div class="border border-success p-2 mb-2 border-opacity-50">This is 50% opacity success border</div>
