Mga hangganan
Gumamit ng mga kagamitan sa hangganan upang mabilis na mai-istilo ang hangganan at border-radius ng isang elemento. Mahusay para sa mga larawan, mga pindutan, o anumang iba pang elemento.
Border
Gumamit ng mga kagamitan sa hangganan upang magdagdag o mag-alis ng mga hangganan ng isang elemento. Pumili mula sa lahat ng mga hangganan o isa-isa.
Additive
Magdagdag ng mga hangganan sa mga custom na elemento:
<span class="border"></span>
<span class="border-top"></span>
<span class="border-end"></span>
<span class="border-bottom"></span>
<span class="border-start"></span>
Subtractive
O alisin ang mga hangganan:
<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>
Kulay
Baguhin ang kulay ng hangganan gamit ang mga utility na binuo sa aming mga kulay ng 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>
O baguhin ang default border-color
ng isang bahagi:
<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>
Opacity
Idinagdag sa v5.2.0Ang mga utility ng Bootstrap border-{color}
ay nabuo gamit ang Sass gamit ang mga variable ng CSS. Nagbibigay-daan ito para sa real-time na mga pagbabago sa kulay nang walang compilation at dynamic na alpha transparency na mga pagbabago.
Paano ito gumagana
Isaalang-alang ang aming default .border-success
na utility.
.border-success {
--bs-border-opacity: 1;
border-color: rgba(var(--bs-success-rgb), var(--bs-border-opacity)) !important;
}
Gumagamit kami ng RGB na bersyon ng aming --bs-success
(na may halaga ng 25, 135, 84
) CSS variable at nag-attach ng pangalawang CSS variable, --bs-border-opacity
, para sa alpha transparency (na may default na value 1
salamat sa lokal na CSS variable). Ibig sabihin, anumang oras na gagamitin mo .border-success
ngayon, ang iyong nakalkulang color
halaga ay rgba(25, 135, 84, 1)
. Ang lokal na variable ng CSS sa loob ng bawat .border-*
klase ay umiiwas sa mga isyu sa pagmamana kaya ang mga nested instance ng mga utility ay hindi awtomatikong may binagong alpha transparency.
Halimbawa
Para baguhin ang opacity na iyon, i-override sa --bs-border-opacity
pamamagitan ng mga custom na istilo o inline na istilo.
<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>
O, pumili mula sa alinman sa mga .border-opacity
utility:
<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>
Lapad
<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>
Radius
Magdagdag ng mga klase sa isang elemento upang madaling ikot ang mga sulok nito.
<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="...">
Mga sukat
Gamitin ang mga scaling class para sa mas malaki o mas maliit na bilugan na sulok. Ang mga sukat ay mula 0
hanggang 5
, at maaaring i-configure sa pamamagitan ng pagbabago sa mga utility API.
<img src="..." class="rounded-0" alt="...">
<img src="..." class="rounded-1" alt="...">
<img src="..." class="rounded-2" alt="...">
<img src="..." class="rounded-3" alt="...">
