Hi,
I just noticed that the text
A green background indicates that the reader is recommended for your
operating system. The recommendations are based on ease of use and
install and do not reflect the technical merits of the software itself.
should not be displayed when JavaScript is disabled since otherwise one
looks for a recommendation that is not displayed. This could be done by
putting the above text into a div with "display:none" that is set to
block once the JS to select the CSS runs.
Cheers,
