why is my footer NOT responsive in layout ASP .NET core?

I have a problem when I show a table in my view and it shows that bellow the footer and it has a very bad shape in various scales even in scaffolded pages. I use bootswatch theme and here is my _layout.cshtml code. but I think the header is ok and when I run my app on Production Mode the footer is even worst. it is going to the center of the screen!!

  <!DOCTYPE html>
   <html lang="en">
    <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>@ViewData["Title"] - آزمون سنج دقیق</title>
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />
    <link rel="stylesheet" href="~/css/site.css" asp-append-version="true" />
