Centering forms
By default, Convert Forms outputs the form aligned to the left. If your layout requires the form to appear centered horizontally, Convert Forms includes a built-in CSS helper class that does exactly that, without writing any custom CSS.
How it works
Convert Forms provides helper CSS classes that can be applied directly to a form. The cf-iscentered class centers the form container horizontally within its parent element.
Steps to center the form
- Go to Components → Convert Forms
- Open the form you want to center
- Navigate to Design → Advanced
- In the Class Suffix field, enter:
cf-iscentered
That’s it. The form will now be centered on the page.
Notes & tips
- The form will be centered relative to its container. If the container itself is very wide or constrained by your template, the visual result depends on that layout.
- You can combine cf-iscentered with other helper classes by separating them with a space.
- This helper affects only horizontal alignment, not vertical positioning.
