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

<nav aria-label="breadcrumb">

Kaiwehewehe

Ka taapiri aunoatia nga kaiwehewehe ki te CSS ::beforeme te content. Ka taea te whakarereke ma te whakarereke i tetahi taonga ritenga CSS rohe --bs-breadcrumb-divider, ma te $breadcrumb-dividertaurangi Sass ranei - $breadcrumb-divider-flippedmo tana hoa RTL, ki te hiahiatia. Ka taunoa matou ki ta maatau taurangi Sass, kua tautuhia hei takahuri ki te taonga ritenga. Ma tenei ara, ka whiwhi koe i te wehewehe o te ao ka taea e koe te whakakore me te kore e whakahiato CSS i nga wa katoa.

html

<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>

I te whakarereketanga ma te Sass, ka hiahiatia te mahi kii hei whakaputa i nga korukī huri noa i te aho. Hei tauira, ma >te whakamahi hei kaiwehewehe, ka taea e koe te whakamahi i tenei:

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

Ka taea hoki te whakamahi i te ata SVG kua whakauruhia . Hoatuhia ma o maatau taonga ritenga CSS, whakamahi ranei i te taurangi Sass.

Te whakamahi i te SVG kua whakauruhia

Ko te whakauru i te SVG hei raraunga URI e hiahia ana kia mawhiti te URL i etahi tohu, te nuinga <, >me te #. Koia te take ka tukuna te $breadcrumb-dividertaurangi ki roto i ta maatau escape-svg()mahi Sass . I te wa e whakamahi ana koe i te taonga ritenga CSS, me mawhiti atu koe i to SVG i to URL. Panuitia nga whakamarama a Kevin Weber mo CodePen mo nga korero taipitopito mo nga mea ka mawhiti.

html

<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='%236c757d'/%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>

$breadcrumb-divider: url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' width='8' height='8'><path d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z' fill='#{$breadcrumb-divider-color}'/></svg>");

Ka taea hoki te tango i te tautuhinga wehewehe --bs-breadcrumb-divider: '';(ko nga aho kau i roto i nga taonga ritenga CSS ka kiia he uara), ka tautuhi ranei i te taurangi Sass ki $breadcrumb-divider: none;.

html

<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;

Te urunga
