    <p>A better way for me to have phrased this question (in hindsight) would have been "How can you access content generated automatically by CSS without using JavaScript?", and that these questions are relevant:</p> <ul> <li><a href="https://stackoverflow.com/questions/2358107/is-it-possible-to-access-the-content-generated-by-a-css-before-rule">Is it possible to access the content generated by a css :before rule?</a></li> <li><a href="https://stackoverflow.com/questions/2651739/how-to-access-css-generated-content-with-javascript">How to access CSS generated content with JavaScript</a></li> </ul> <p>It looks like accessing the automatically generated counter values is not easy even with JavaScript, and not possible without it, so that answers my question.</p> <p>There are a number of documents from the W3C that discuss counters and generated content, but none as far as I could tell discuss referencing generated content from other parts of a document:</p> <ul> <li><a href="http://www.w3.org/TR/css-counter-styles-3/" rel="nofollow noreferrer">CSS Counter Styles Level 3</a></li> <li><a href="http://www.w3.org/TR/2011/WD-css3-lists-20110524/" rel="nofollow noreferrer">CSS Lists and Counters Module Level 3</a></li> <li><a href="http://www.w3.org/TR/2003/WD-css3-content-20030514/" rel="nofollow noreferrer">CSS Generated and Replaced Content Module</a></li> </ul> <p>There <em>is</em> <a href="http://www.w3.org/TR/1998/NOTE-CSS-potential-19981210#id10710829041" rel="nofollow noreferrer">a note in the W3C's <em>List of suggested extensions to CSS</em></a> that mentions exactly the cross-reference problem - it comes from an email written in <em>1998</em>, and I haven't found any follow-up work, so I guess this wasn't a high priority.</p> <p><strong>Update</strong></p> <p>The <a href="http://www.w3.org/TR/css3-gcpm/" rel="nofollow noreferrer">CSS Generated Content for Paged Media Module</a> <a href="http://www.w3.org/TR/css3-gcpm/#cross-references" rel="nofollow noreferrer">discusses cross references explicitly</a>, and describes the <code>target-counter</code> and <code>target-text</code> functions to implement them with CSS. However, this is a working draft dated 29 November 2011; these functions don't appear to be implemented in any major browser. An <a href="http://alistapart.com/article/building-books-with-css3" rel="nofollow noreferrer">article from A List Apart</a> talks about using these CSS features to produce PDF eBooks from HTML using some random propriety tools.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
