Different login page for every client (on one server) - html

Question

Scenario:
Currently, we have a website tool in asp.net MVC (www.tool.com/login).
Now, the client is looking into customizing the login page for several customers and they will have their own domain (but only one server for all).
for example:
www.client1.com/login,
www.client2.com/login,
www.client3.com/login
Yell at me if this is a stupid question.
But please help and give me an idea on how to implement it.
Should I create different login htmls for each client?

Related to my comment -
Create a Table with ClientInfo in DB:
Title
BackgroundColor
Language
URL --> This has to be unique for this to work [client1, client2]. Don't save the full URL -- Just the Host
Let's say you are passing a Model --> LoginModel to your LoginPage.cshtml
public class LoginModel
{
public string UserName { get; set; }
public string Password { get; set; }
public StyleDTO ClientStyles { get; set; }
}
public class StyleDTO
{
public string Title { get; set; }
public string LogoPath { get; set; }
public string BackGroundColor { get; set; }
}
In your controller when you load View:
public ActionResult Login()
{
var clientUrl = HttpContext.Current.Request.Url.Host;
var cs = dbContext.ClientInfo.First(s => s.Url == clientUrl);
var model = new LoginModel()
{
ClientStyles = new StyleDTO()
{
Title = cs.Title,
LogoPath = cs.LogoPath,
BackGroundColor = cs.BackGroundColor
}
};
}
then in your login View (LoginPage.cshtml):
#model LoginModel
<div style="background-color: #Model.BackGroundColor">
<h1>#Model.Title</h1>
</div>

Answer 2

create a config file with variables for client1, client2, client3
Keep same login page html and based on HTTP_referer pick one of the config variable and render the page based on that.
