Background color product page


How do we get white background color on Woocommerce product page?
We have tried pasting this in custom css, but it doesn’t work:

.woocommerce .site-main {
background-color: #FFFFFF;
background-image: none;

Any suggestions?
Our product page:

Hello there,

Could you please try the following?

Let me know how it goes. I’ll wait to hear back from you regarding your stats.

Warmest regards,
