Hello, @Soumya,
That CSS code is for the border radius, and it applies to the forms as well, so you can simply remove the Dokan classes from that code. It will not harm your site.
Then the code will be like the below:
input[type="text"],
input[type="number"],
input[type="email"],
input[type="search"],
input[type="password"],
input[type="tel"],
input[type="url"],
.with-border-radius{
border-radius: 4px;
}
