Using CSS files
From MyWiki
In the "hello" folder create a folder called "static" and within it create a folder called "hello"
In this "hello" folder create a file called "styles.css" with the following contents:
h1{
font-family: sans-serif;
font-size: 90px;
text-align: center;
color: green;
}Then make the greet.html file look like below:
{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
<title> Hello</title>
<link href="{% static 'hello/styles.css' %}" rel="stylesheet">
</head>
<body>
<h1> Hello, {{ name }}!</h1>
</body>
</html>
