how to change the white highlight at the submit button?

Hi Nicholas,

Thanks for reaching out to Jotform Support. I checked your website, where the form is embedded, but I don't see any white highlight in it. Check this out:

Can you confirm if you still need any assistance with this? I can see that you have Custom CSS codes applied in your form, so I assume you've sorted it out using CSS.

Let us know if there's anything else we can help you with.
