Do like this
base.html
<!DOCTYPE html>
{% load static %}
<html lang="en">
<head>
<!--- Add all your meta tags css files --->
<title>{% block title %}{% endblock %}</title>
{% block extra_head_links %}
{% endblock %}
</head>
<body>
{% block content %}{% endblock %}
</body>
</html>
inside your index.html
{% extends 'main/base.html' %}
{% load static %}
{% block title %}
{{title}}
{% endblock %}
{% block extra_head_links %}
<link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}">
{% endblock %}
{% block content %}
<main>
<h1>GHBDTN</h1>
<body>
<div class="grid-wrapper">
<header class="grid-header">
<img class="circles" src="{% static "main/img/main8.jpg" %}" alt="main pic">
<p>Предоставим качественное образование, <br>
поможем понять школьную программу, <br>
улучшить оценки и <br>
подготовиться к экзаменам</p>
</header>
</div>
</body>
</main>
{% endblock %}
