How to make mod_autoindex mobile-friendly?

[Jim Avera <jim.avera@xxxxxxxxx>]

Google complains that directories displayed by mod_autoindex have "Mobile Usability Issues", specifically:

Clickable elements too close together
Text too small to read
Viewport not set

What's the best way to fix this?

I can't change the Apache server config.  My top-level .htaccess file contains

Options +Indexes
IndexOptions +NameWidth=* Charset=UTF-8
IndexOptions FancyIndexing FoldersFirst HTMLTable
IndexOrderDefault Ascending Name

Thanks in advance,
