modal

Boa noite!

Td bem com vcs?

Peguei um codigo de modal muito util para mim, mas ele naun sai do lugar, estou tentando posiciona lo em outro lugar e naun consigo.

Ja fiz de tudo e nada resolveu alguém pode me ajudar?

Gostaria que ele ficasse, aonde eu colocar ele aceitar e rodar.

segue o codigo abaixo:

<style>
body {font-family: Arial, Helvetica, sans-serif;}
* {box-sizing: border-box;}

/ Button used to ppen the contact form - fixed at the bottom of the page /

.open-button {
 background-color: #555;
 color: white;
 padding: 16px 20px;
 border: none;
 cursor: pointer;
 opacity: 0.8;
 position: fixed;
 bottom: 23px;
 right: 28px;
 width: 280px;
}

/ The popup form - hidden by default /

.form-popup {
 display: none;
 position: fixed;
 bottom: 0;
 right: 15px;
 border: 3px solid #f1f1f1;
}

/ Add styles to the form container /

.form-container {
 max-width: 300px;
 padding: 10px;
 background-color: white;
}

/ Full-width input fields /
.form-container input[type=text], .form-container input[type=file], .form-container input[type=textarea] {

 width: 100%;
 padding: 15px;
 margin: 5px 0 22px 0;
 border: none;
 background: #f1f1f1;
}

/ When the inputs get focus, do something /
.form-container input[type=text]:focus, .form-container input[type=file]:focus, .form-container input[type=textarea]:focus {

 background-color: #ddd;
 outline: none;
}

/ Set a style for the submit/login button /
.form-container .btn {

 background-color: #4CAF50;
 color: white;
 padding: 16px 20px;
 border: none;
 cursor: pointer;
 width: 100%;
 margin-bottom:10px;
 opacity: 0.8;
}

/ Add a red background color to the cancel button /
.form-container .cancel {

 background-color: red;
}

/ Add some hover effects to buttons /
.form-container .btn:hover, .open-button:hover {

 opacity: 1;
}
</style>

<button class="open-button" onclick="closeForm()">Open Form</button>

<div class="form-popup" id="myForm">
 <form action="/action_page.php" class="form-container">
 <h1> <img src="http://mercatotal.com.br/gnservice/img/logotipo2.png" width="170px" height="70px"/></h1>
