I have the following django template:
/*The body and the header are being positioned using CSS Grid:*/
body {
display: grid;
grid-template-columns: 1fr 4fr 1fr 1fr;
grid-template-rows: 150px 1fr 50px;
min-height: 100vh;
font-size: 18pt;
font-family: 'Cormorant Garamond', serif !important;
font-weight: 400;
color: black;
background-color: #ffe3dd;
margin: 0;
}
header {
display: grid;
grid-template-columns: subgrid;
grid-column-start: 2;
grid-column-end: 4;
}
<header>
<h1 class="home">
<a href="{% url 'home' %}">Vilanovella</a>
</h1>
<span class="menubar">
<a href="{% url 'archive' %}">Archive</a>
<a href="{% url 'about' %}">About</a>
</span>
</header>
<div class="post-area">
{% block content %} {% endblock content %}
</div>
<footer>

</footer>
However Google Chrome gives and "Invalid Property Value" error for "grid-template-columns: subgrid;".
Can anyone help me understand this? I don't see what would be wrong about using 'subgrid' as value but perhaps someone here can help me understand?
Thank you!
