Mention "spoilers in the docs where you present "Collapsible blocks"

[couleurm]

When searching spoilers I couldn't find, and it'd be cool to mention the term somewhere so people who search for that

I also tried to do something like that, but I found a workaround

#### <p hidden class="fake-toc"> Code </p>

combined with extra_css

h1:has(.fake-toc),
h2:has(.fake-toc),
h3:has(.fake-toc),
h4:has(.fake-toc),
h5:has(.fake-toc),
h6:has(.fake-toc) {
    float: left;
}

.fake-toc {
    margin: 0;
    padding: 0;
}

.fake-toc+.headerlink {
    float: left;
    margin-left: -1.5em !important;
}

that works pretty nice
