Navigating icons - how to insert

[Skviotu]

I would like add icons to the navigation menus, those on the left and those with red colour.

How to achieve this using main.css.

client store: roxiecosmetics.co.uk

Kinda like this:

.main-nav__item[href$="beauty-chairs-beds"] {
  padding-left: 3rem !important;
  margin-left: -2rem;
  background: url(/cdn/shop/files/roxie_cosmetics_logo_rgb.png?v=1682595150&width=100) no-repeat;
  background-size: 2rem;
  background-position: center left;
}

See how selector uses the link HREF?
