Isikhundla
Sebenzisa lezi zinsiza ze-shorthand ukuze ulungiselele ngokushesha indawo yento.
Amanani esikhundla
Amakilasi okubeka ngokushesha ayatholakala, nakuba engaphenduli.
<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>
Hlela izakhi
Hlela ama-elementi kalula ngezinsiza zokubeka onqenqemeni. Ifomethi ithi {property}-{position}
.
Lapho impahla ingenye ye:
top
top
- endaweni eqondilestart
- endaweni evundlileleft
(ku-LTR)bottom
bottom
- endaweni eqondileend
- endaweni evundlileright
(ku-LTR)
Lapho isikhundla singesinye salezi:
0
- ukuze uthole0
indawo enqenqemeni50
- ukuze uthole50%
indawo enqenqemeni100
- ukuze uthole100%
indawo enqenqemeni
(Ungengeza amanani ezindawo ezengeziwe ngokungeza okufakiwe $position-values
kokuhluka kwemephu ye-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>
Izakhi ezimaphakathi
Ukwengeza, ungakwazi futhi ukubeka phakathi ama-elementi nesigaba sensiza yokuguqula .translate-middle
.
Lesi sigaba sisebenzisa ukuguqulwa translateX(-50%)
kanye translateY(-50%)
nesici lapho, ngokuhambisana nezinsiza zokubeka unqenqema, ikuvumela ukuthi ubeke phakathi nendawo into.
<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>
Ngokungeza .translate-middle-x
noma .translate-middle-y
amakilasi, ama-elementi angamiswa kuphela endaweni evundlile noma eqondile.
<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>

Ungasebenzisa lawa makilasi anezingxenye ezikhona ukuze udale ezintsha. Khumbula ukuthi ungakwazi ukunweba ukusebenza kwayo ngokungeza okufakiwe $position-values
kokuguquguqukayo.

Sass
Amamephu
Amanani ensiza yendawo ezenzakalelayo amenyezelwa kumephu ye-Sass, bese esetshenziselwa ukukhiqiza izinsiza zethu.
$position-values: (
0: 0,
50: 50%,
