I have a full calender page (index) through home controller. currently it is set to have empty layout. I want to use the _Layout so it can have the same look as the other pages.
calender page has:
@{
    Layout = null;
}
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body class="container">
    <div id="calender"></div>
    <div id="myModal" class="modal fade" role="dialog">
        <div class="modal-dialog">
            <div class="modal-content">

and the _Layout  looks like this:

So if I remove the below lines of code from the full calender page, i will get an empty page and the callender won't show anymore.
why is that?
@{
    Layout = null;
}
