HTML_standard color change

I create a html_standard report for my mp3's to copy and paste into Excel. When the html is generated some lines are grey and some white ie: grey, white and so on. My question is how can I change the color of the grey lines to white so that I don't have to keep changing them in Excel and if it can be done please tell me where to change the color cause it's been years since I've done HTML and besides that they're using CSS anyway so I'm lost. Thanks in advance.

change the line with
.odd { background-color: #ccc; }
to
.odd { background-color: #fff; }

Thanks for the help, really appreciate it.
