    Form Builder 4.0: Changing the font size doesn't affect the fields

    Asked by candy on April 20, 2017 at 09:29 AM

    Our user named "springest" has reported us that he can not change the font size of the form.

    I have tested and I have seen that changing the font size only changes the text of the buttons. The field labels are not affected.

    Both Advanced Designer and Form Designer does not affect the font size both in the preview mode and in the builder as you can see below:

    As a quick workaround, I have suggested injecting CSS codes in order to change the font size. This works as you can see the screenshot below:

    I'm unable to reproduce this changes are being applied to editor stage correctly, I assume this was fixed in one of the recent commits, marking this one as resolved. Feel free to re-open if the issue still persists.

    Dear Kaan,

    Yes, you are right. Berkay told me previously that this issue occurred because the user had some CSS codes came from the database that we do not see in the interface.

    I have told this user to remove the theme and add again. The issue has fixed this way.

    For your information,

    Thanks.
