posisi
Gunakake utilitas shorthand iki kanggo ngatur posisi unsur kanthi cepet.
Nilai posisi
Kelas posisi cepet kasedhiya, sanajan ora responsif.
<div class="position-static">...</div>
<div class="position-relative">...</div>
<div class="position-absolute">...</div>
<div class="position-fixed">...</div>
<div class="position-sticky">...</div>
Atur unsur
Atur unsur kanthi gampang nganggo utilitas posisi pinggir. Format kasebut yaiku {property}-{position}
.
Ing endi properti minangka salah sawijining:
top
top
- kanggo posisi vertikalstart
- kanggo posisi horisontalleft
(ing LTR)bottom
bottom
- kanggo posisi vertikalend
- kanggo posisi horisontalright
(ing LTR)
Posisi ngendi iku salah siji saka:
0
- kanggo0
posisi pinggiran50
- kanggo50%
posisi pinggiran100
- kanggo100%
posisi pinggiran
(Sampeyan bisa nambahake nilai posisi kanthi nambahake entri menyang $position-values
variabel peta Sass.)
<div class="position-relative">
<div class="position-absolute top-0 start-0"></div>
<div class="position-absolute top-0 end-0"></div>
<div class="position-absolute top-50 start-50"></div>
<div class="position-absolute bottom-50 end-50"></div>
<div class="position-absolute bottom-0 start-0"></div>
<div class="position-absolute bottom-0 end-0"></div>
</div>
unsur tengah
Kajaba iku, sampeyan uga bisa dadi pusat unsur kanthi kelas sarana transformasi .translate-middle
.
Kelas iki ditrapake transformasi translateX(-50%)
lan translateY(-50%)
unsur kang, ing kombinasi karo keperluan posisi pinggiran, ngijini sampeyan kanggo pusat Absolute unsur.
<div class="position-relative">
<div class="position-absolute top-0 start-0 translate-middle"></div>
<div class="position-absolute top-0 start-50 translate-middle"></div>
<div class="position-absolute top-0 start-100 translate-middle"></div>
<div class="position-absolute top-50 start-0 translate-middle"></div>
<div class="position-absolute top-50 start-50 translate-middle"></div>
<div class="position-absolute top-50 start-100 translate-middle"></div>
<div class="position-absolute top-100 start-0 translate-middle"></div>
<div class="position-absolute top-100 start-50 translate-middle"></div>
<div class="position-absolute top-100 start-100 translate-middle"></div>
</div>
Kanthi nambah .translate-middle-x
utawa .translate-middle-y
kelas, unsur bisa dipanggonke mung ing arah horisontal utawa vertikal.
<div class="position-relative">
<div class="position-absolute top-0 start-0"></div>
<div class="position-absolute top-0 start-50 translate-middle-x"></div>
<div class="position-absolute top-0 end-0"></div>
<div class="position-absolute top-50 start-0 translate-middle-y"></div>
<div class="position-absolute top-50 start-50 translate-middle"></div>
<div class="position-absolute top-50 end-0 translate-middle-y"></div>
<div class="position-absolute bottom-0 start-0"></div>
<div class="position-absolute bottom-0 start-50 translate-middle-x"></div>
<div class="position-absolute bottom-0 end-0"></div>
</div>
Tuladha
Ing ngisor iki sawetara conto urip nyata saka kelas kasebut:
<button type="button" class="btn btn-primary position-relative">
Mails <span class="position-absolute top-0 start-100 translate-middle badge rounded-pill bg-secondary">+99 <span class="visually-hidden">unread messages</span></span>
</button>
<button type="button" class="btn btn-dark position-relative">

</button>
Sampeyan bisa nggunakake kelas iki karo komponen sing wis ana kanggo nggawe anyar. Elinga yen sampeyan bisa nambah fungsi kanthi nambahake entri menyang $position-values
variabel.
<div class="position-relative m-4">
<div class="progress" style="height: 1px;">
<div class="progress-bar" role="progressbar" style="width: 50%;" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<button type="button" class="position-absolute top-0 start-0 translate-middle btn btn-sm btn-primary rounded-pill" style="width: 2rem; height:2rem;">1</button>
<button type="button" class="position-absolute top-0 start-50 translate-middle btn btn-sm btn-primary rounded-pill" style="width: 2rem; height:2rem;">2</button>
<button type="button" class="position-absolute top-0 start-100 translate-middle btn btn-sm btn-secondary rounded-pill" style="width: 2rem; height:2rem;">3</button>
