    <p>The usual method for creating cross-references in LaTeX is to put a <code>\label</code> inside something you want to refer to later, and then use <code>\ref</code>. So for example, writing <code>as we saw in Section~\ref{intro}</code> in the LaTeX source might produce "as we saw in Section 1" in the final output. Is it possible to get the same effect using just HTML and CSS? Newer features of CSS allow sections and so on to be numbered automatically, but I haven't found anything that lets you reference these counter values from elsewhere in the document.</p> <p>Here is a concrete example:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;Cross references&lt;/title&gt; &lt;meta charset="utf-8"&gt; &lt;style type="text/css"&gt; body { counter-reset: section; } section &gt; h1::before { counter-increment: section; content: counter(section) ". "; } &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;section&gt; &lt;h1 id="intro"&gt;Introduction&lt;/h1&gt; &lt;p&gt;Pineapples contain essential vitamins.&lt;/p&gt; &lt;/section&gt; &lt;section&gt; &lt;h1&gt;Further discourse on pineapples&lt;/h1&gt; &lt;p&gt;As we saw in Section ??, pineapples contain essential vitamins.&lt;/p&gt; &lt;/section&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>In this example, all the section headings are prepended with an automatically generated number. I would like to know if there is any HTML markup or CSS styling I could use in place of <code>??</code> that will insert the number corresponding to <code>#intro</code>.</p> <p>I realize I could use <code>&lt;a href="#intro"&gt;</code> to create a cross-hyperlink to the Introduction, but I'd like to include the section number in the link text as well.</p> <p>If this is not possible with HTML and CSS alone, are there any JavaScript libraries for adding cross-references within a document?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
