Pożizzjoni
Uża dawn l-utilitajiet shorthand biex tikkonfigura malajr il-pożizzjoni ta 'element.
Valuri tal-pożizzjoni
Klassijiet ta 'pożizzjonament ta' malajr huma disponibbli, għalkemm mhumiex reattivi.
<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>
Irranġa l-elementi
Irranġa l-elementi faċilment bl-utilitajiet tal-pożizzjonament tat-tarf. Il-format huwa {property}-{position}
.
Fejn il-proprjetà hija waħda minn:
top

(Tista 'żżid aktar valuri ta' pożizzjoni billi żżid entrati mal- $position-values
varjabbli tal-mappa 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>
Elementi taċ-ċentru
Barra minn hekk, tista 'wkoll tiċċentra l-elementi bil-klassi ta' utilità tat-trasformazzjoni .translate-middle
.
Din il-klassi tapplika t-trasformazzjonijiet translateX(-50%)
u translateY(-50%)
għall-element li, flimkien mal-utilitajiet tal-pożizzjonament tat-tarf, jippermettilek li tiċċentra element assolut.
<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>
Billi żżid .translate-middle-x
jew .translate-middle-y
klassijiet, l-elementi jistgħu jitqiegħdu biss f'direzzjoni orizzontali jew vertikali.
<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>
Eżempji
Hawn huma xi eżempji tal-ħajja reali ta’ dawn il-klassijiet:

Tista' tuża dawn il-klassijiet b'komponenti eżistenti biex toħloq oħrajn ġodda. Ftakar li tista' testendi l-funzjonalità tagħha billi żżid entrati mal- $position-values
varjabbli.

Sass
Mapep
Il-valuri tal-utilità tal-pożizzjoni default huma ddikjarati f'mappa Sass, imbagħad jintużaw biex jiġġeneraw l-utilitajiet tagħna.
$position-values: (
0: 0,
50: 50%,
100: 100%
);
Utilitajiet API
L-utilitajiet tal-pożizzjoni huma ddikjarati fl-API tal-utilitajiet tagħna f' scss/_utilities.scss
. Tgħallem kif tuża l-API tal-utilitajiet.
