How to rename meta data entries in Quarto Book - quarto

Question

I am using Quarto Book for writing an online Book for my students on scientific writing skills (see www.politik-wissenschaft.at).
I want to add the bibliographic entry of this book at the start site (index.qmd / index.html). I used the abstract option for doing that. This works fine, but the title of this meta data entry is now called "Zusammenfassung" (i.e., abstract).
Is there a way to change this title to "How to cite", for example?
Furthermore, after updating Quarto CLI to 1.2.313 this information ("Zusammenfassung") is not only printed on the index.html file, but on the head of all other sites as well. How can I switched that off, so that these meta data information is only shown at the start site (i.e., index.html).

Answer 1

You can change the meta data using template-partials. Add the following to your _quarto.yml file:
template-partials:
- title-block.html
And create the title-block.html file (see here the original file) and change the abstract-title to your liking:
<header id="title-block-header">
<h1 class="title">$title$</h1>
$if(subtitle)$
<p class="subtitle">$subtitle$</p>
$endif$
$for(author)$
<p class="author">$author$</p>
$endfor$
$if(date)$
<p class="date">$date$</p>
$endif$
$if(abstract)$
<div class="abstract">
<div class="abstract-title">How to Cite </div>
$abstract$
</div>
$endif$
</header>
Different Option:
add a css file and change the text via css (usually not recommended):
styles.css
div.abstract-title {
visibility: hidden;
}
div.abstract-title:before {
content: "How to cite";
visibility: visible;
}
