How Do I Create A Custom Login Screen For Single Site on Multisite Network?

I'd like to create a custom-styled login screen for a single site on my network.

Upon login the user will be redirected to the site homepage.

I've read: https://premium.wpmudev.org/blog/customize-wordpress-login/

Does this apply to Multisite as well? If there is a revised procedure can you share it with me?

Thanks
