Iwwer

Bootstrap "Spinner" kënne benotzt ginn fir de Luedezoustand an Äre Projeten ze weisen. Si sinn nëmme mat HTML an CSS gebaut, dat heescht datt Dir kee JavaScript braucht fir se ze kreéieren. Dir braucht awer e puer personaliséiert JavaScript fir hir Visibilitéit ze wiesselen. Hir Erscheinung, Ausrichtung an Gréisst kënne ganz einfach mat eisen erstaunlechen Utilityklassen personaliséiert ginn.

Fir Accessibilitéitszwecker enthält all Loader hei role="status"an eng nestéiert <span class="visually-hidden">Loading...</span>.

Den Animatiounseffekt vun dëser Komponent hänkt vun der prefers-reduced-motionMedienufro of. Kuckt d' Reduktiounsbewegungssektioun vun eiser Accessibilitéitsdokumentatioun .

Grenz Spinner

Benotzt d'Grenzspinner fir e liichte Luedeindikator.

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

Faarwen

De Grenzspinner benotzt currentColorfir seng border-color, dat heescht datt Dir d'Faarf mat Textfaarf Utilities personaliséiere kënnt . Dir kënnt all vun eisen Textfaarf Utilities op der Standard Spinner benotzen.

<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>

Firwat net border-colorUtilities benotzen? All Grenzspinner spezifizéiert eng transparentGrenz fir op d'mannst eng Säit, sou datt .border-{color}Utilities dat iwwerschreiden.
