Luachan suidheachaidh

Tha clasaichean suidheachaidh luath rim faighinn, ged nach eil iad freagairteach.

<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>

Cuir air dòigh eileamaidean

Cuir air dòigh eileamaidean gu furasta leis na goireasan suidheachaidh iomall. Tha an cruth {property}-{position}.

Far a bheil seilbh mar aon de:

toptop- airson suidheachadh dìreach
start- airson suidheachadh còmhnard left(ann an LTR)
bottombottom- airson suidheachadh dìreach
end- airson suidheachadh còmhnard right(ann an LTR)

Far a bheil suidheachadh mar aon de:

0- airson 0suidheachadh iomall
50- airson 50%suidheachadh iomall
100- airson 100%suidheachadh iomall

(Faodaidh tu barrachd luachan suidheachaidh a chur ris le bhith a’ cur inntrigidhean ri $position-valuescaochladair mapa Sass.)

html

<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>

Feartan an ionaid

A bharrachd air an sin, faodaidh tu cuideachd na h-eileamaidean a mheadhanachadh leis a ’chlas cruth-atharrachaidh goireas .translate-middle.

Bidh an clas seo a’ buntainn ris na h-atharrachaidhean translateX(-50%)agus translateY(-50%)ris an eileamaid a tha, ann an co-bhonn ris na goireasan suidheachaidh iomall, a’ toirt cothrom dhut eileamaid iomlan a mheadhanachadh.

html

<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>

Le bhith a 'cur ris .translate-middle-xno .translate-middle-yclasaichean, chan urrainnear eileamaidean a shuidheachadh ach ann an stiùireadh còmhnard no dìreach.

html

<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>

Eisimpleirean

Faodaidh tu na clasaichean sin a chleachdadh leis na co-phàirtean a th’ ann mu thràth gus feadhainn ùra a chruthachadh. Cuimhnich gun urrainn dhut a ghnìomhachd a leudachadh le bhith a’ cur inntrigidhean ris a’ $position-valueschaochladair.

Sass

Mapaichean

Tha luachan goireas suidheachadh bunaiteach air an ainmeachadh ann am mapa Sass, an uairsin air an cleachdadh gus ar goireasan a ghineadh.

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

Utilities API

Tha goireasan suidheachaidh air an ainmeachadh anns na goireasan API againn ann an scss/_utilities.scss. Ionnsaich mar a chleachdas tu an API Utilities.
