Can't persuade product name to centre

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.3.29
-- Browser(s) name and version -- : Firefox 34.0.5

Try as I might, I can't work out why the product name appears left aligned on the Shop pages of this site. I want it centred, and that's how it's set in HikaShop. I guess it must be picking up its formatting from the main site template, but I can't see why. Probably I'm missing something really obvious - any ideas?

You might have added a link to the hidden info in your post (which us regular humans wouldn't see, indeed), but without seeing the site it will be only guesswork for everyone else as well.
So, if not included "hidden" already, please post a link?

Sorry - it was included and hidden, because the site isn't officially available yet. Here it is, though: Mother's Milk Books - I don't suppose it matters.

Add this code at the end of your css file(templates/mothersmilkdec295/css/template.css):

.art-postcontent .hikashop_product_name a {
    text-align: center;
}

Great, thanks very much. Any idea why that happened on this site, when I don't have the problem on any of the other HikaShop sites that I run? I'm not aware of anything being significantly different about the template.

It was because on line 66 in your css file, there is css selector with high specificity(priority) for all links in component area of template with value text-align:left;
It has higher specificity than hikashop styles therefore all product names were aligned left.

I see. That's really helpful. Thanks very much
