Bain úsáid as na fóntais ghearrshaolacha seo chun suíomh eiliminte a chumrú go tapa.
Luachanna poist
Tá ranganna suite tapa ar fáil, cé nach bhfuil siad sofhreagrach.

Eilimintí a shocrú
Eilimintí a shocrú go héasca leis an imeall suite fóntais. Tá an fhormáid {property}-{position}
.
Sa chás gur ceann de na nithe seo a leanas an mhaoin :
top
- dontop
suíomh ingearachstart
- donleft
suíomh cothrománach (i LTR)bottom
- donbottom
suíomh ingearachend
- donright
suíomh cothrománach (i LTR)
Áit a bhfuil an suíomh mar cheann de:

(Is féidir leat tuilleadh luachanna suímh a chur leis trí iontrálacha a chur leis an $position-values
athróg léarscáile 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>
Eilimintí ionaid
Ina theannta sin , is féidir leat ionad freisin na heilimintí leis an rang fóntais a athrú .translate-middle
.
Baineann an rang seo leis na claochluithe translateX(-50%)
agus translateY(-50%)
leis an eilimint a ligeann duit, i gcomhcheangal leis na fóntais suite imeall, duit eilimint a lárú go hiomlán.
<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>
Trí chur leis .translate-middle-x
nó .translate-middle-y
ranganna, ní féidir eilimintí a shuíomh ach amháin i dtreo cothrománach nó ingearach.
<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>
