color background of lines in html export

Hi Robby,

I have a question for you about the Tellico html export.
After an export of my Tellico collection in html it's very difficult to see the color difference between lines.
I expected an alternation of line backgrounds: One line with white background, one line with blue background and so on...but, for my eyes, the difference between backgrounds is not strong enough. The blue background is almost white and it's difficult to differentiate lines.
How can I change this ? Perhaps it's in the tellico2html.xsl file but I don't know how to change the color background of lines.

Could you help me please ?
Thanks in advance.
