Fix css registration form layout fields WordPress

Hello dear freelancer. I have a WordPress site, I'm using Astra & Beaver builder. I'm using a plugin for our wholesale customers (Woocommerce wholesale). But the registration and login fields don't look right. [login to view URL] [login to view URL] I want the fields to look full-width with the name of the fields inside the box instead of outside. We can't, I repeat WE CAN'T use a plugin or a custom form for this, we need to use this URL from wocommerce wholesale, we can't use thememylogin or elementor, we need to take this page and do a custom CSS to make it look right. I need this to be done now in the next few hours. Also, I don't have access to cpanel, this needs to be done 100% on WPadmin. If you understand the project and know 100% you can do it, in the time and in the budget, please say what is 2+2 at the beginning of your proposal. Thanks
