I set the following content in the home_info.html, which I put under /layouts/partial:
{{- with site.Params.homeInfoParams }}
<article class="first-entry home-info">
    <header class="entry-header">
        <h1>{{ .Title | markdownify }}</h1>

    <footer class="entry-footer">
        {{ partial "social_icons.html" (dict "align" site.Params.homeInfoParams.AlignSocialIconsTo) }}
    </footer>

Probably, I used the wrong directive for the language choices.
Particularly, I refer to the part that begins for:
<script>
    {{- if eq site.Language `en` -}}
Is there anyone who cal help me?
