You can include Font Awesome on your theme for icons. Go into your theme.liquid in your Layouts folder in Online Store > Themes > Actions > Edit Code
Open the file and look for the closing head tag and place this before it:
<script src="https://kit.fontawesome.com/f7cf0a6419.js"></script>
//place this script above the closing head tag
</head> // <---- This is the ending head tag
Then open your header.liquid file in your sections folder and ctrl + f for “announcement-bar__message”. You should see this line:
Hello friend, i use the minimal theme and i basically just want to remove all text and replace with the 3 icons. Person icon for account, basket and magnifying glass for search. This is my current lay out, how can i change this?
Just find the icon you like and you can place it anywhere on your site with the tags, and put the class that they provide you on the site in the class field.
