What I'm trying to get across is that the index entries are formatted
like this in HTML:
<dt>alias, Table and Column Aliases, Column Labels</dt>
<dd>
<dl>
<dt>for table name in query, Joins Between Tables</dt>
<dt>in the FROM clause, Table and Column Aliases</dt>
<dt>in the select list, Column Labels</dt>
</dl>
</dd>
(Note I've stripped this down for clarity).
The <dd> section should be indented for readabilty; browsers usually do this
by default.
However digging about in the style sheets, we have a:
dd {
...
margin-left:0;
}
which is unindenting it (evidently originates in a file "_reboot.scss").
See attached screenshots:
- "pg-docs-index-dd-issue-with-no-indentation.jpg"
-> the index as-is
- "pg-docs-index-dd-issue-with-indentation-added.jpg"
-> here I've dynamically modified the indentation to 2rem, which IMHO
is a vast improvement.
I suspect the above dd style might be global to the site, so there'd
probably need to be a specific style for the index, e.g.:
#BOOKINDEX dd {
margin-left:2rem;
}

I'm not asking for emphasis or syntax highlighting here, my attempt to explain
the issue using only plain text didn't work so well :).
