Need Help to Style Form App by Shopify

Topic summary

Styling the Shopify-provided FORM app to match site design is the central issue. The goal is to change visual appearance via CSS (Cascading Style Sheets), which control look-and-feel like fonts and corner roundness.

Requested changes:

  • Remove border radius on form fields (sharp edges at 0px).
  • Adjust font sizes for the header, subheader, form fields, and text below the form.

A live example link was shared, noting the form appears near the bottom of the page; a screenshot was provided but not essential to the technical issue.

Recent update: One reply states the Shopify FORM app does not support custom CSS and recommends switching to the AVADA Email Marketing app, which supports adding CSS to forms.

The original poster prefers to continue using the free Shopify FORM app and believes there is a coding method to style it, but lacks the skill and seeks guidance.

Outcome/status: No solution has been provided yet. The discussion remains open. Key unanswered question: Is there a workable way to style the Shopify FORM app (e.g., fonts and border radius) without built-in custom CSS support.

I’m using the FORM app provided by Shopify. How do you change the style of the form???

  • removing the radius on the form field so that it is a sharp edge 0px

  • changing the font sizes on the header, sub header and form fields themselves and text below the form

Ultimately is to have the form and text match the rest of the website.

You’ll find the form at near the bottom of the page, https://noemielcote.com/collections/available

Hi @noemielcote

I have checked and found that the app does not support custom CSS.

You should consider using the app AVADA Email Marketing, as we also support adding CSS to forms to meet your specific requirements.

I hope this helps

Best,

Thanks for offering a different solution. I still want to work with the free FORM App by Shopify. There is definitely a coding way to style it, I just don’t have that skill.
