Hi @djnbob
Do you mind providing your website so we can provide a code appropriate for you?
Topic summary
Goal: Shorten “Add to Cart” and payment buttons in the Shopify Flow theme to match the “Notify me” button. A screenshot illustrates the mismatch.
Update: A helper requested the store URL to provide theme-specific code; the site is isopoddepot.com.
Solution provided: Edit Online Store > Themes > Edit code > Assets > theme.min.css and add a CSS rule targeting the Add to Cart button: #AddToCartForm button#AddToCart { max-width: 300px !important; }. This sets a maximum width so the button matches the desired size.
Outcome: The requester confirmed with a thank you, indicating the Add to Cart button fix worked. The screenshot was central to identifying the issue.
Status: Partially resolved. The solution specifically targets the Add to Cart button; payment buttons (“Buy now,” etc.) were not explicitly addressed. If needed, similar CSS selectors should be applied to those buttons to achieve consistent sizing. No further action items or disagreements noted.
