Font Size MarketPress

Hello,

I would like to increase the font size on my Products page for the MarketPress ecommerce plugin. I was given the following code and told it was an issue with my theme. I do not know where to place the following code to increase the font size for the MarketPress ecommerce plugin.

My website can be found here:

Code:

mp_product_list h3 {
font-size:40px;
}

Thank you.

 

Thanks, but I solved this one on my own.
