How to bold the last element in smarty?

Question

PHP

Hello. The breadcrumb template contains the following line

<a href="{$e.url}">{$delimiter_left}{if $allow_tags}{$e.name|htmlspecialchars_decode}{else}{$e.name|htmlspecialchars_decode|strip_tags}{/if}{$delimiter_right}</a>

which outputs breadcrumbs with a link. Tell me how you can bold the first or last element of breadcrumbs?

Answer 1

{if $smarty.foreach / section.crumbs.last}...{/if}
Surely bypassing the array of crumbs is done through foreach or section

Answer 2

This needs to be done with CSS, not Smarty

Answer 3

First element
Last element
Also, maybe this: :nth-last-child
