This is an improvement, thanks.

Looks good, although it doesn't work perfectly.
It does not work with the CSS classes for multi-level indices in the
development version:
<tr><td class="printindex-index-entry"><a
href="Inserting-Accents.html#index-Accents_002c-inserting">Accents,
inserting</a></td><td class="printindex-index-section"><a
href="Inserting-Accents.html">Inserting Accents</a></td></tr>
<tr><td class="printindex-index-entry"><code
class="code">accesskey</code></td><td></td></tr>
<tr><td class="printindex-index-subentry-level-1"><a
href="HTML-Customization-Variables-List.html#index-accesskey-customization-variable-for">customization
variable for</a></td><td class="printindex-index-section"><a
href="HTML-Customization-Variables-List.html">HTML Customization Variables
List</a></td></tr>
<tr><td class="printindex-index-subentry-level-1"><a
href="Writing-a-Menu.html#index-accesskey-in-HTML-output-of-menus">in HTML
output of menus</a></td><td class="printindex-index-section"><a
href="Writing-a-Menu.html">Writing a Menu</a></td></tr>
<tr><td class="printindex-index-subentry-level-1"><a
href="Texinfo-Document-Structure.html#index-accesskey-in-HTML-output-of-nodes">in
HTML output of nodes</a></td><td class="printindex-index-section"><a
href="Texinfo-Document-Structure.html">Texinfo Document Structure</a></td></tr>
<tr><td class="printindex-index-entry"><a
href="_0040unnumbered-_0040appendix.html#index-_003cacknowledgements_003e-DocBook-tag"><code
class="code"><acknowledgements></code> DocBook tag</a></td><td
class="printindex-index-section"><a
href="_0040unnumbered-_0040appendix.html"><code class="code">@unnumbered
@appendix</code></a></td></tr>
The "printindex-index-entry" rows are highlighted but not the
"printindex-index-subentry-level-1" rows. "printindex-index-subentry-level-2"
is also possible. From style.css:
/* For indices. Make the rows stand out on hover to better visualize which
section corresponds to which entry. */
table[class*="printindex"] tr:hover td[class*="index-entry"],
table[class*="printindex"] tr:hover td[class*="index-section"] {
background:#f9f6ed;
}
It would probably be accommodated by adding in addition:
table[class*="printindex"] tr:hover td[class*="index-subentry"],
Less importantly, at
https://www.gnu.org/software/emacs/manual/html_node/elisp/Index.html#Index_fn_letter-A.,
you can see there is a small section that is not highlighted when you
hover over each index entry. This is due to a small cell <td> </td>.
You may decide this is a very minor problem and not worth trying to fix.
(It might not be possible to find those cells with CSS as they don't
have a class set.)
That page was generated with Texinfo 7.0.3. The small cell is not
present with output from 7.2 (I haven't tracked down exactly when
the change was made.)

It seems to work fine, thanks.
