Hello,
I tried to change this to after, but now I see double
Do you get the double font-size?
Add the folowing custom to Theme Options > Custom CSS to reduce the subtitle font-size in the minicart
.widget_shopping_cart_content .product-subtitle + h2 {
font-size: 14px;
}
Or do you want to change the title size for the title and subtitle here http://prntscr.com/v9jvao ?
