Css Changes On Cs-Cart

On cs-cart css is very hard to edit. Why it is made on this way? I just want to Google inspect any item that want to change but could not find it. For example,

1. I would like to make main menu

text-transform: lowercase;

font-size: 12px;

2. Top quick links: bolder and 13 px

3. To change the color of subcategories

4. to change the color of placeholder on search bar

5. to change the color of hover on shopping cart

Could someone advise to me please


Just use CSS section in the Theme editor to add custom CSS rules
