Answer 1

There you go,
<h1>Popup without JavaScript</h1>
<div class="box">
<a class="button" href="#popup1">Let me Pop up</a>
</div>
<div id="popup1" class="overlay">
<div class="popup">
<h2>Here i am</h2>
<a class="close" href="#">×</a>
<div class="content">
Thanks for pop me out of that button, but now i'm done so you can close this window.
</div>
</div>
</div>

Try the snippet below:
html, body{
width: 100%;
height: 100%;
padding: 0;
margin: 0;
}
.container{
width:100%;
height: 100%;
margin: 0;
position: absolute;
background: rgba(220,220,220, .5);
}
.modal{
position: relative;
top: 40%;
margin: 0 auto;
height: 100px;
width: 150px;
background: white;
border: 1px solid #aaa;
}
p{
margin: 0;
}
<div class='container'>
<div class='modal'>Modal window</div>
</div>
<p> other content</p>
Try with absolute positioned container div and a child div with actual content. I added paragraph with content Other content to illustrate the effect
