  </ol>
</nav>

Abahluli

Izahluli zongezwa ngokuzenzekelayo kwiCSS ::beforenge content. Zingatshintshwa ngokuguqula ipropathi yendawo yeCSS yendawo --bs-breadcrumb-divider, okanye ngokusebenzisa i- $breadcrumb-dividerSass variable - kunye $breadcrumb-divider-flippedne-RTL iqabane layo, ukuba kuyimfuneko. Asigqibekanga kuguquguquko lwethu lwe-Sass, olusetwa njengokubuyela umva kwipropati yesiko. Ngale ndlela, ufumana isahluli sehlabathi onokuthi usikhuphe ngaphandle kokubuyisela i-CSS nangaliphi na ixesha.

html
