Hi,
In CSS, you can have specific rules depending on parents.
That why HikaShop have a lot of classes and ids, so you can create a specific rule for one module or one page.
An example with your demo website:
.moduletable-cart .hikashop_product_price {
color: #FFF;
margin-left: 5px;
}
Which create a rule just for the module cart in the website.
