Topic summary
Shopify product page variant descriptions are not displaying bold text and consistent font sizes, despite formatting done via the third‑party “Variant Description” app. Screenshots and a theme preview link were shared to illustrate the mismatch.
One suggestion is to fix styling via theme CSS. A contributor provided a CSS snippet targeting table text in the product info container and instructed adding it at the bottom of Assets > base.css to enforce font size, letter spacing, line height, and theme font settings.
An alternative viewpoint advises contacting the app’s support first, citing a likely conflict causing the missing bold styling. They note that editing theme code or HTML can work but is not recommended if the issue originates from the app.
Action taken: the exact CSS guidance and file path were provided to the store owner. No confirmation yet that the change resolved the issue.
Key terms: CSS (Cascading Style Sheets) controls visual styling in Shopify theme files; base.css is the main stylesheet; third‑party app conflicts can override or block expected formatting.
Status: unresolved/ongoing, pending the merchant’s test or app support response. Images are central to understanding the formatting problem.
