How to change size of a subject?

Topic summary

Main issue: Reduce the “trust bar” title (the heading for the trust badges section on the product page) from 18px to 14px, and understand where in Liquid this can be edited.

Recent updates:

  • One helper offered to assist via collaborator access, noting they can’t guide “blindly” through the customizer.
  • A concrete, code-free fix was provided: in Shopify Admin > Online Store > Theme > Customize > Theme Settings > Custom CSS, add a rule to set the trust bar title to 14px using the .trustBarTitle selector with !important.

Key details:

  • CSS snippet suggested: .trustBarTitle { font-size: 14px !important; }
  • This solution avoids editing Liquid and directly targets the relevant class.
  • The request about locating and editing the Liquid section/text was not specifically addressed.
  • Screenshots and a product URL were shared to show the current vs. desired size, which are central to the issue context.

Status: Actionable CSS change provided; no confirmation of success yet. Liquid/template location for text changes remains unanswered, so the topic appears open.
