Edit font size in ec_price_container

[krstyles]

Is there any waya to edit the font size in the ec_price_container? I use the type 5 to display the products in the shop, but the font size is to small for me.

I tried to modify it with own css:

.ec_price_container_type5 {font-size: 20px

But the size is the same.

Any ideas for that? Thanks.
