change the size of the price text

Where can i find the css to change the size of the item price?

Is this in a hikashop file?

I am using the artisteer and when i change my css it applie to all the text on the page, so was wondering if it is in the hikashop css.

Thx

All the CSS of HikaShop is in one place: in the tab Display of the configuration, you can edit the front end CSS file.

The price style is defined by:
span.hikashop_product_price_full{
text-align: center;
font-weight:bold;
display:block;
margin-bottom:5px;
}

Hello

I changed the price size, but then also the text size in small cart module has changed and now its too big to fit in

Is there a way to keep price text in cart display smaller, but larger in product listing?

Sure.
You need to change:
span.hikashop_product_price_full{
by:
.hikashop_product_page span.hikashop_product_price_full{
