<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item active" aria-current="page">Home</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item"><a href="#">Library</a></li>
    <li class="breadcrumb-item active" aria-current="page">Data</li>
  </ol>
</nav>

Divizeur

Divizyon yo otomatikman ajoute nan CSS atravè ::beforeak content. Yo ka chanje lè w modifye yon pwopriyete lokal CSS koutim --bs-breadcrumb-divider, oswa atravè $breadcrumb-dividervaryab Sass la - ak $breadcrumb-divider-flippedpou kontrepati RTL li yo, si sa nesesè. Nou default nan varyab Sass nou an, ki mete kòm yon sekou nan pwopriyete a koutim. Nan fason sa a, ou jwenn yon divizyon mondyal ke ou ka pase sou plas san yo pa recompiling CSS nenpòt ki lè.

<nav style="--bs-breadcrumb-divider: '>';" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

Lè modifye atravè Sass, fonksyon quote yo oblije jenere quotes alantou yon fisèl. Pou egzanp, lè l sèvi avèk >kòm divize an, ou ka itilize sa a:

$breadcrumb-divider: quote(">");

Li posib tou pou itilize yon ikòn SVG entegre . Aplike li atravè pwopriyete koutim CSS nou an, oswa itilize varyab Sass la.

<nav style="--bs-breadcrumb-divider: url(&#34;data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E&#34;);" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

$breadcrumb-divider: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='currentColor'/%3E%3C/svg%3E");

Ou kapab tou retire anviwònman divize an --bs-breadcrumb-divider: '';(fisèl vid nan pwopriyete koutim CSS konte kòm yon valè), oswa mete varyab Sass la sou $breadcrumb-divider: none;.

<nav style="--bs-breadcrumb-divider: '';" aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

$breadcrumb-divider: none;

Aksesiblite

Piske breadcrumbs bay yon navigasyon, li se yon bon lide pou ajoute yon etikèt ki siyifikatif tankou aria-label="breadcrumb"pou dekri ki kalite navigasyon bay nan <nav>eleman an, osi byen ke aplike yon aria-current="page"pou dènye atik ansanm lan pou endike ke li reprezante paj aktyèl la.
