Product box lengths and cart background change

Hi,

For your first question, you have three solutions:
1. you reduce the number of columns of your listing of products so that you have more width per box. There is an option in it for that.
2. you reduce the length of you products names or increase it so that you always have the same length.
3. you use CSS to force the height of the box divs. The CSS to use will depend of your website CSS. If you could give the url of that page, we should be able to tell you more precisely.

The second question is actually not related to HikaShop. The display of the title of the modules in joomla as well as the chrome around the modules are handled by the template. Here are some pages explaining module chroming in joomla templates :

You need to edit the CSS of HikaShop via the interface in the tab display of the config. There, you can add something like that:
div.hikashop_subcontainer { height:250px; }
