Dreuchd
Cleachd na goireasan làmh-ghoirid seo airson suidheachadh eileamaid a rèiteachadh gu sgiobalta.
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:
top

- airson suidheachadh dìreachstart
- airson suidheachadh còmhnardleft
(ann an LTR)bottom
bottom
- airson suidheachadh dìreachend
- airson suidheachadh còmhnardright
(ann an LTR)
Far a bheil suidheachadh mar aon de:
0
- airson0
suidheachadh iomall50
- airson50%
suidheachadh iomall100
- airson100%
suidheachadh iomall
(Faodaidh tu barrachd luachan suidheachaidh a chur ris le bhith a’ cur inntrigidhean ri $position-values
caochladair mapa 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>
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.
<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-x
no .translate-middle-y
clasaichean, chan urrainnear eileamaidean a shuidheachadh ach ann an stiùireadh còmhnard no dìreach.
<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>

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-values
chaochladair.
