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>

Swiaki swa le xikarhi

Ku engetela kwalaho, u nga ha tlhela u hlanganisa swiaki hi tlilasi ya vukorhokeri bya ku hundzula .translate-middle.

Tlilasi leyi yi tirhisa ku hundzuka translateX(-50%)na translateY(-50%)le ka elemente leyi, hi ku hlanganisiwa na switirhisiwa swa ku veka edge positioning, yi ku pfumelelaka ku absolute center an element.

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>

Hi ku engetela .translate-middle-xkumbe .translate-middle-ytitlilasi, swiaki swi nga vekiwa ntsena eka tlhelo leri nga etlhelo kumbe leri yimisiweke.

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>

Swikombiso

Hi leswi swikombiso swin’wana swa xiviri swa vutomi bya titlilasi leti:
