Fronteiras
Use as utilidades de bordos para estilizar rapidamente o bordo e o radio do bordo dun elemento. Ideal para imaxes, botóns ou calquera outro elemento.
Borde
Use as utilidades de bordos para engadir ou eliminar bordos dun elemento. Escolle entre todas as fronteiras ou unha á vez.
Aditivo
Engade bordos aos elementos personalizados:
<span class="border"></span>
<span class="border-top"></span>
<span class="border-end"></span>
<span class="border-bottom"></span>
<span class="border-start"></span>
Subtractivo
Ou elimina os bordos:
<span class="border border-0"></span>
<span class="border border-top-0"></span>
<span class="border border-end-0"></span>
<span class="border border-bottom-0"></span>
<span class="border border-start-0"></span>
Cor
Cambia a cor do bordo usando utilidades creadas nas cores do noso tema.
<span class="border border-primary"></span>
<span class="border border-secondary"></span>
<span class="border border-success"></span>
<span class="border border-danger"></span>
<span class="border border-warning"></span>
<span class="border border-info"></span>
<span class="border border-light"></span>
<span class="border border-dark"></span>
<span class="border border-white"></span>
Ou modifique o valor predeterminado border-color
dun compoñente:
<div class="mb-4">
<label for="exampleFormControlInput1" class="form-label">Email address</label>
<input type="email" class="form-control border-success" id="exampleFormControlInput1" placeholder="[email protected]">
</div>
<div class="h4 pb-2 mb-4 text-danger border-bottom border-danger">
Dangerous heading
</div>
<div class="p-3 bg-info bg-opacity-10 border border-info border-start-0 rounded-end">
Changing border color and width
</div>
Opacidade
Engadido na v5.2.0As utilidades de arranque border-{color}
xéranse con Sass usando variables CSS. Isto permite cambios de cor en tempo real sen compilación e cambios dinámicos de transparencia alfa.
Cómo funciona
Considere a nosa .border-success
utilidade predeterminada.
.border-success {
--bs-border-opacity: 1;
border-color: rgba(var(--bs-success-rgb), var(--bs-border-opacity)) !important;
}
Usamos unha versión RGB da nosa --bs-success
(co valor de 25, 135, 84
) variable CSS e adxuntamos unha segunda variable CSS, --bs-border-opacity
, para a transparencia alfa (cun valor predeterminado 1
grazas a unha variable CSS local). Isto significa que sempre que uses agora, o teu valor .border-success
calculado é . A variable CSS local dentro de cada clase evita problemas de herdanza polo que as instancias aniñadas das utilidades non teñen automaticamente unha transparencia alfa modificada.color
rgba(25, 135, 84, 1)
.border-*
Exemplo
Para cambiar esa opacidade, anula --bs-border-opacity
mediante estilos personalizados ou estilos en liña.
<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>
Ou escolle entre calquera das .border-opacity
utilidades:
<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>
<div class="border border-success p-2 mb-2 border-opacity-25">This is 25% opacity success border</div>
<div class="border border-success p-2 border-opacity-10">This is 10% opacity success border</div>
Anchura
<span class="border border-1"></span>
<span class="border border-2"></span>
<span class="border border-3"></span>
<span class="border border-4"></span>
<span class="border border-5"></span>
Raio
Engade clases a un elemento para redondear facilmente as súas esquinas.
<img src="..." class="rounded" alt="...">
<img src="..." class="rounded-top" alt="...">
<img src="..." class="rounded-end" alt="...">
<img src="..." class="rounded-bottom" alt="...">
<img src="..." class="rounded-start" alt="...">
<img src="..." class="rounded-circle" alt="...">
<img src="..." class="rounded-pill" alt="...">
Tallas
Use as clases de escala para cantos redondeados máis grandes ou pequenos. Os tamaños van desde 0
ata 5
, e pódense configurar modificando a API de utilidades.
<img src="..." class="rounded-0" alt="...">
<img src="..." class="rounded-1" alt="...">
