Font size, colour and layout

Hi,

If you follow our documentation on customizing the CSS on your website ( www.hikashop.com/support/documentation/1...ize-the-display.html ), you'll see that these a tags have CSS on them either directly in the header of the page (added by your template, I suppose in the index.php file), or in the templates/YOUR_TEMPLATE/css/template.css file of your template:
monosnap.com/file/7amtFlp0eR8TtHT4ab6S6sUYKqxJn8
So you need to check with your template provider as HikaShop is not involved here.

But in any case, if you want to force something, you don't know to know where it is styled.
For example, for the product name links, you can simply add such CSS:
.hikashop_product_name a{ color : green !important; }
in any of the CSS files loaded on the page (be it the HikaShop frontend or style CSS files or your template CSS files), anywhere in them (provided it is valid CSS), and it will work.
