Shopify is hard! I need to add line breaks to the main page head line so it reads...
How do I do this? You can see the page here https://we-are-fussy.myshopify.com
You'd either need to create a js script to split the spaces or, ideally, add a textbox with Richtext in your section so you could edit your text with greater accuracy.
In case you're unfamiliar with .Liquid you'll likely want to hire a Shopify developer to assist you.
For the way it's currently setup, unfortunately not.
You'd need a a textarea or richtext box instead of the standard textbox in your section, this could be done only with custom coding.
This is how they look in the customize page:
Usually themes' sections come with the former built-in. With the latter you can add bold, italic, line breaks and so on and so forth.
