{{ $url := replace .Permalink ( printf "%s" .Site.BaseURL) "" }}
{{ $.Scratch.Add "path" .Site.BaseURL }}
<ol class="breadcrumbs">
<li><a href="/">home</a></li>
{{ range $index, $element := split $url "/" }}
{{ $.Scratch.Add "path" $element }}
{{ if ne $element "" }}
<li><a href='{{ $.Scratch.Get "path" }}'>{{ . }}</a></li>
{{ $.Scratch.Add "path" "/" }}
{{ end }}
{{ end }}
</ol>
