python manage.py startapp custom_admin

{% extends "admin/base_site.html" %}

{% block title %}Change Password{% endblock %}

{% block content %}
<div id="content-main">
    <h2>Change Password</h2>
    <form method="post" action="">
        {% csrf_token %}
        {{ form.as_p }}
       <input type="submit" value="Change Password">
    </form>
</div>
{% endblock %}

body {
    background-color: #f0f0f0;
}

#content-main {
    background-color: #ffffff;
    padding: 20px;
    margin: 20px;
    border-radius: 5px;
}

h2 {
    margin-top: 0;
}

input[type="submit"] {
    background-color: #4CAF50;
    color: white;
    padding: 10px 20px;
    border: none;
    border-radius: 5px;
