From Shopify admin, go to Online Store → Themes, then select "Customize" for the target theme.

In the page selector at the top of the theme editor, select "Home page → Products → Default product."
(3) Enter custom CSS
Select the product information section on the left, then enter the following code in "Custom CSS."
(4) Save
Select "Save" in the upper-right corner.
