Dawn Theme - Adjust width of white Register Container

I used this code to add a white container behind the register form. Now i would like to adjust the white container so that it like the container in the picture below. The width is already 100% and i dont understand how i can make it wider. Does anyone know how it is possible?

.customer.register {
  background: white;
  border-radius: 20px;
  width: 100%;
}

.customer.register h1 {
  font-weight: bold;
}

I tried to use this code in base.css

.customer.register.section-template--19011406037325__main-padding {
max-width: 90%;
}
form#RegisterForm {
width: 50%;
margin-left: 25%;
}

Does anyone have an idea how I can change this? I would also like to do this for the customer.addresses page.

Hello @Roxolot

You can try this code: it will be helpful to you

Go to the Online Store->Theme->Edit code->Assets->base.css>Add this code at the bottom.

.customer.login.section-template--19011406037325__main-padding {
    max-width: 100% !important;
}
