The Price List component options include a Custom CSS field, so you can add your own styling rules on top of whatever your template already provides.

Some common cases

Remove the extra white space below a paragraph:

.pricelist p {
    margin-bottom: 0px;
}

Place the category image to the left of the category description:

.pricelist .category-image {
    float: left;
    max-width: 200px;
    margin-bottom: 20px;
    margin-right: 20px;
}
