How to change font size of product name ?

May I know how to change font size of product name ?
I'm using style "Pictureblue"

Hi,

You can edit the css to do so.
Go in System>Display and edit the front end css file.
Then add something like that

.hikashop_product_name_main{
font-size:20
}

you can obviously change 20 to what fits better to your needs.

I added the code but not working.

I'm using style "pictureblue" from Hikashop.
www.hikashop.com/en/hikashop/styles-for-hikashop.html

If I use "default" for frontend CSS, then product name display correctly without adding any code.
But, If I use style "pictureblue" then product name size became very small, even adding code still not possible change font size.

This is the example page for check.

You should use that CSS instead then:

.hikashop_product_name_main{
font-size: 20px !important;
}

That should force it over the style and the template's CSS.
