Can't give span.hikashop_product_name less line-he

-- HikaShop version -- : Essential: 2.5.0
-- Joomla version -- : 3.4.2
-- Error-message(debug-mod must be tuned on) -- : No error, CSS problem

I can't change the line-height of span.hikashop_product_name. No mather what I try. I checked via firebug and the right css is read but the line-height can't be smaller than is displayed now. Even if I set line-height to 0 it remains the same. I can make it bigger, but not smaller.

The first product has no <br> all others does. I have this problem since the start and can't find a solution for this. Hoepefully it's simpel and do I miss something.

See image as example what I want.

ALWAYS when you have a problem, even for a long timne, and than you post a question the solution pops up.

What I found. I need to set line-height for the DIV (div.hikashop_subcontainer). Aparantley otherwise you can't lower the line-height. Learned something

So now I only need to add margins to .hikashop_product_name for positioning.
