Border spinner

Sèvi ak spinners fwontyè yo pou yon endikatè loading ki lejè.

<div class="spinner-border" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Koulè

Spinner fwontyè a itilize currentColorpou li border-color, sa vle di ou ka Customize koulè a ak sèvis piblik koulè tèks . Ou ka itilize nenpòt nan sèvis piblik koulè tèks nou yo sou spinner estanda a.

<div class="spinner-border text-primary" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-secondary" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-success" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-danger" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-warning" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-info" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-light" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-dark" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Poukisa nou pa sèvi ak border-colorsèvis piblik? Chak spinner fwontyè presize yon transparentfwontyè pou omwen yon bò, kidonk .border-{color}sèvis piblik yo ta pase sou sa.

Ap grandi spinner

Si ou pa anpenpan yon spinner fwontyè, chanje nan spinner grandi. Pandan ke li pa teknikman vire, li repete grandi!

<div class="spinner-grow" role="status">
  <span class="visually-hidden">Loading...</span>
</div>
