For rounded button corners…
Add the style add-on
Open the form
Click on the button
Click on Styles
Go to Element Styles
In the Advanced CSS add something like this:
border-radius: 8px;
You can change that value to suit your preference.
To center the button you can go to the Wrap Styles above that section and in the Advanced CSS add:
text-align:center;
For max width click the Advanced tab top left by Form Fields and Emails & Actions. Then go to Styles
Then go to Container Styles
Then Advanced CSS
Then input
max-width:800px;
Hello @sdagencia! Thanks for your answer, could you tell me the name of the plugin please? Would it be possible to do it with css from the customizer?
@josesg95 Yes, you can add custom CSS to your theme’s additional CSS section to change the appearance of the Ninja Forms. https://wpengine.com/resources/customize-theme-css/
Sorry for the late reply @jmcelhaney, thanks a lot and have a great day!
