<h2>Here i am</h2>
<a class="close" href="#">×</a>
<div class="content">

Answer 1

add z-index to .overlay class
.overlay {
position: fixed;
top: 0;
bottom: 0;
left: 0;
right: 0;
background: rgba(0, 0, 0, 0.7);
transition: opacity 500ms;
visibility: hidden;
opacity: 0;
z-index:9999;/*Add this property*/
}
replace your html like
<div id="popup1" class="overlay">
<div class="popup">
<h2>Here i am</h2>
<a class="close" href="#">×</a>
<div class="">
