Neve Form Fields
Please note that some of the plugins might have their own styling options that can override the theme settings. For example, in WPForms, the plugin style can be changed/disabled from its settings - click to see image.
Those are available in Dashboard -> Appearance -> Customize -> Form Fields. Let's explore these options on a contact form created with the WPForms plugin.
The fields settings can change the style of the boxes where text can be written.
This set of options allows the text color and typography options to be changed. For more details about the typography properties, please check Neve Typography documentation.
The labels can be found above or next to the fields, and have mainly the same typography options as inputs, including a spacing control.
The buttons within the contact forms can inherit the style of Neve buttons, options available in Customizer - Buttons.
