Isikhundla

Sebenzisa lezi zinsiza ze-shorthand ukuze ulungiselele ngokushesha indawo yento.

Kuleli khasi

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:

toptop- endaweni eqondile
start- ngesikhundla esivundlile left(ku-LTR)
bottombottom- endaweni eqondile
end- ngesikhundla esivundlile right(ku-LTR)

Lapho isikhundla singesinye salezi:

0- ukuze uthole 0indawo enqenqemeni
50- ukuze uthole 50%indawo enqenqemeni
100- ukuze uthole 100%indawo enqenqemeni

(Ungengeza amanani ezindawo ezengeziwe ngokungeza okufakiwe $position-valueskokuhluka 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

Ngaphezu kwalokho, 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-xnoma .translate-middle-yamakilasi, 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>

Izibonelo

Nazi izibonelo zempilo yangempela zalawa makilasi:

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

<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>

Sass

Amamephu

Amanani ensiza yendawo ezenzakalelayo amenyezelwa kumephu ye-Sass, bese esetshenziselwa ukukhiqiza izinsiza zethu.

$position-values: (
  0: 0,
  50: 50%,
  100: 100%
);
