Tuladha
Bootstrap kalebu sawetara gaya tombol sing wis ditemtokake, saben duwe tujuan semantik dhewe, kanthi sawetara tambahan sing dibuwang kanggo kontrol liyane.

Nuduhake makna kanggo teknologi assistive
Nggunakake warna kanggo nambah makna mung menehi indikasi visual, sing ora bakal dikirim menyang pangguna teknologi bantu - kayata pembaca layar. Priksa manawa informasi sing dituduhake kanthi warna katon jelas saka isi kasebut (umpamane teks sing katon), utawa kalebu liwat cara alternatif, kayata teks tambahan sing didhelikake karo .visually-hidden
kelas.
Pateni bungkus teks
Yen sampeyan ora pengin teks tombol kanggo mbungkus, sampeyan bisa nambah .text-nowrap
kelas kanggo tombol. Ing Sass, sampeyan bisa nyetel $btn-white-space: nowrap
kanggo mateni bungkus teks kanggo saben tombol.
Tag tombol
Kelas .btn
kasebut dirancang kanggo digunakake karo <button>
unsur kasebut. Nanging, sampeyan uga bisa nggunakake kelas iki ing <a>
utawa <input>
unsur (sanajan sawetara browser bisa nggunakake rendering rada beda).
Nalika nggunakake kelas tombol ing <a>
unsur sing digunakake kanggo micu fungsi ing kaca (kaya ambruk isi), tinimbang ngubungake menyang kaca anyar utawa bagean ing kaca saiki, pranala iki kudu diwenehi role="button"
kanggo tepat ngirim tujuane kanggo teknologi bantuan kayata maca layar.
<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">
Tombol outline
Mbutuhake tombol, nanging ora werna latar mburi dibalèkaké padha nggawa? Ganti kelas modifier standar karo .btn-outline-*
sing kanggo mbusak kabeh gambar latar mburi lan werna ing tombol sembarang.
<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>
Ukuran
Apik tombol luwih gedhe utawa luwih cilik? Tambah .btn-lg
utawa .btn-sm
kanggo ukuran tambahan.
<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-secondary btn-lg">Large button</button>
<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-secondary btn-sm">Small button</button>
negara dipatèni
Nggawe tombol katon ora aktif kanthi nambahake disabled
atribut boolean menyang <button>
unsur apa wae. Tombol dipatèni wis pointer-events: none
diterapake, nyegah hover lan status aktif saka micu.
<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
<button type="button" class="btn btn-secondary btn-lg" disabled>Button</button>
Tombol sing dipateni nggunakake <a>
unsur tumindak rada beda:
<a>
s ora ndhukungdisabled
atribut, dadi sampeyan kudu nambah.disabled
kelas kanggo nggawe visual katon dipatèni.- Sawetara gaya ramah mangsa kalebu kanggo mateni kabeh
pointer-events
tombol anchor. - Tombol sing dipatèni kudu kalebu
aria-disabled="true"
atribut kanggo nunjukake status unsur kanggo teknologi bantu.
<a href="#" class="btn btn-primary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Link</a>
Kaveat fungsi link
Kelas .disabled
digunakake pointer-events: none
kanggo nyoba mateni fungsi link <a>
s, nanging properti CSS durung standar. Kajaba iku, sanajan ing browser sing ndhukung pointer-events: none
, pandhu arah keyboard tetep ora kena pengaruh, tegese pangguna keyboard sing katon lan pangguna teknologi pitulung isih bisa ngaktifake tautan kasebut. Supaya aman, saliyane aria-disabled="true"
, uga kalebu tabindex="-1"
atribut ing pranala kasebut kanggo nyegah wong-wong mau nampa fokus keyboard, lan nggunakake JavaScript khusus kanggo mateni fungsine kabeh.
Tombol blokir
Gawe tumpukan responsif kanthi "tombol blok" sing ambane kaya sing ana ing Bootstrap 4 kanthi campuran utilitas tampilan lan jurang. Kanthi nggunakake utilitas tinimbang kelas khusus tombol, kita duwe kontrol sing luwih gedhe babagan spasi, alignment, lan tindak tanduk responsif.
<div class="d-grid gap-2">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Kene kita nggawe variasi responsif, miwiti karo tombol vertikal dibandhingke nganti md
breakpoint, ngendi .d-md-block
ngganti .d-grid
kelas, mangkono nullifying gap-2
sarana. Owahi ukuran browser sampeyan kanggo ndeleng owah-owahan.
<div class="d-grid gap-2 d-md-block">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Sampeyan bisa nyetel ambane tombol pamblokiran karo kelas jembar kolom kothak. Contone, kanggo "tombol pamblokiran" setengah jembaré, gunakake .col-6
. Pusat kasebut kanthi horisontal .mx-auto
uga.
<div class="d-grid gap-2 col-6 mx-auto">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Utilitas tambahan bisa digunakake kanggo nyetel alignment tombol nalika horisontal. Ing kene, kita wis njupuk conto responsif sadurunge lan nambah sawetara utilitas fleksibel lan utilitas margin ing tombol kanggo nyelarasake tombol nalika ora ditumpuk maneh.
<div class="d-grid gap-2 d-md-flex justify-content-md-end">
<button class="btn btn-primary me-md-2" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Plugin tombol
Plugin tombol ngidini sampeyan nggawe tombol aktif / mateni sing gampang.
Ngalih negara
Tambah data-bs-toggle="button"
kanggo ngalih status tombol active
. Yen sampeyan wis ngalih tombol, sampeyan kudu nambah .active
kelas kanthi manual lan aria-pressed="true"
mesthekake yen wis dikirim kanthi tepat kanggo teknologi pitulung.
<button type="button" class="btn btn-primary" data-bs-toggle="button" autocomplete="off">Toggle button</button>
<button type="button" class="btn btn-primary active" data-bs-toggle="button" autocomplete="off" aria-pressed="true">Active toggle button</button>
<button type="button" class="btn btn-primary" disabled data-bs-toggle="button" autocomplete="off">Disabled toggle button</button>
<a href="#" class="btn btn-primary" role="button" data-bs-toggle="button">Toggle link</a>
<a href="#" class="btn btn-primary active" role="button" data-bs-toggle="button" aria-pressed="true">Active toggle link</a>
<a href="#" class="btn btn-primary disabled" tabindex="-1" aria-disabled="true" role="button" data-bs-toggle="button">Disabled toggle link</a>

Loop
Varian tombol (kanggo tombol reguler lan outline) nggunakake mixin masing-masing karo $theme-colors
peta kita kanggo ngasilake kelas modifier ing scss/_buttons.scss

@include button-variant($value, $value);
}
}
@each $color, $value in $theme-colors {
