How to make the red box focus vertically on the navbar without changing its size or the height of the navbar? I have a bit of css code with which I adjusted the size of the red box without affecting the size of the navbar. Sludos! 

<!DOCTYPE html>
<html lang="es">
    <head>
    <meta charset="UTF-8">
    <title>Ejemplo</title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" integrity="sha384-WskhaSGFgHYWDcbwN70/dfYBj47jz9qbsMId/iRN3ewGhXQFZCSftd1LZCfmhktB" crossorigin="anonymous">
    <style>
            .navbar-brand {
                height: 40px;
            }

            #logo {
                max-height: 40px;
                padding: 0 auto;
                margin-top: 0;
            }
        </style>

it was only necessary to modify the margin-top of the style sheet 

#logo{
    max-height: 40px;
    margin-top: -10px;
}
