Alignment of the product title in the category

HI!
I come to this forum once again humbly request the help of partners!
Previously had problems with Wishilist, my friend Xavier resolved.
Now I have another little problem, which is the display of products in the categories of securities.
By default, the title is left-aligned, but the product code is centralized. I want the title of the product also be centralized.

Note: I make the display of the product title in the categories, not on the actual product page. On the product page, the title can be aligned to the left!
Ah! remembering that the price is too centralized, only the title of the product that is not!

Hi!
You could specify the file path I should edit more specifically?
I want to edit the file directly:

"com_hikashop_business_2.3.0_2014-04-07.tar.gz".

Why the administration of the site I could not!

HI!
Well, I went on my FTP, so I went to the path:
media / com_hikashop / css / frontend_custom.css

I inserted the code that informed me:
div.hikashop_subcontainer span {
text-align: center important;!
}

Only it did not work!
If you can help me!

Hello,
1. Note that you should add the CSS code that Nicolas gave you through the "Front-end CSS File" option of the page "Hikashop->System->Configuration->Display"

2. If it still don't work, can you give me a link to the pag where you are having your issue so that I can directly test it ?

Thanks.

OK
But I think you have misunderstood my question!
I do not want to edit the css file in the administration of my site.
I want to edit the root, ie, inside the zip file:
"com_hikashop_business_2.3.0_2014-04-07.tar.gz".
For the next facilities do not act the same problem.
Do you understand?
