right: 0;
background: rgba(0, 0, 0, 0.7);
transition: opacity 500ms;
visibility: hidden;
opacity: 0;
}
.overlay:target {
visibility: visible;
opacity: 1;
}
.popup {
margin: 70px auto;
padding: 20px;
background: #fff;
border-radius: 5px;
width: 30%;
position: relative;
transition: all 5s ease-in-out;
}
.popup .close {
position: absolute;
top: 20px;
right: 30px;
transition: all 200ms;
font-size: 30px;
font-weight: bold;
text-decoration: none;
color: #333;
}
.popup .content {
max-height: 30%;
overflow: auto;
}
#media screen and (max-width: 700px){
.popup{
width: 70%;
}
<span>Full Recipe</span>
<div id="popup" class="overlay">
<div class="popup">
<h3>Foxtail Millet Porridge:</h3>
<a class="close" href="#">×</a>
<div class="content">
<span>Ingredients:</span>

Answer 1

The content had too big of a height and wouldn't allow scrolling.
Here is the Codepen for the full code
.popup {
transform: translateY(-60px); /* moves container up the page */
margin: 70px auto;
padding: 20px;
background: #fff;
border-radius: 5px;
width: 30%;
position: relative;
transition: all 5s ease-in-out;
}
.content {
height: 250px; /* adjust this depending on the size that you want the
container to be */
}
.popup .content {
overflow-y: scroll;
}
