Bootstrap Grid Doesn't work as expected - django

Question

I want my main content and Sidewidget in the same row. With my knowledge of bootstrap grid, I tried to make this work but the sidewidget is stacking below the content and not in the sides. Here is the required snippets.
body.html
<!-- Navigation -->
{% include 'nav.html' %}
<!-- Page Content -->
<div class="container">
<div class="row">
<div class="col-lg-8 ">
{% block content %}
{% endblock %}
</div>
<div class="col-lg-4">
{% block sidewidget %}
{% endblock %}
</div>
</div>
</div>
<!-- Bootstrap core JavaScript -->
<script src="{% static 'js/jquery.min.js' %}"></script>
<script src="{% static 'js/bootstrap.bundle.min.js' %}"></script>
<script src="{% static 'js/tinymce/tinymce.min.js' %}"></script>
<script type="text/javascript" src="{% static 'js/tinymce/custom.js' %}" ></script>
nav.html
<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
<div class="container">
<a class="navbar-brand" href="#">Start Bootstrap</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Services</a>
</li>
{% if user.is_authenticated %}
<li class="nav-item">
<a class="nav-link" href="{% url 'add' %}">Add Article</a>
</li>
{% endif %}
</ul>
</div>
</div>
My {% block content %}
{% for post in posts %}
<h2 class="mt-4">{{post.title}}</h2>
<!-- Author -->
<p class="lead">
by
{{post.author}}
</p>
<hr>
<!-- Date/Time -->
<p class="lead">Published on <b>{{post.published_date}}</b></p>
<hr>
<!-- Preview Image -->
<img class="img-fluid" src="{{post.image.url}}" alt="Img Placeholder">
<p>{{post.images}}</p>
{% for tag in post.tags.all %}
<p>{{tag.name}}</p>
{% endfor %}
<hr>
<!-- Post Content -->
<p class="lead">{{post.content|safe|truncatewords:"60"|linebreaks}}</p>
<footer class="entry-footer">
<button class="btn btn-primary">Read More</button>
</footer>
<hr>
{% empty %}
<h1> Nothing to display</h1>
{% endfor %}
{% endblock %}
My {% Sidewidget %} block
<!-- Search Widget -->
<div class="card my-4">
<h5 class="card-header">Search</h5>
<div class="card-body">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search for...">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button">Go!</button>
</span>
</div>
</div>
</div>
<!-- Categories Widget -->
<div class="card my-4">
<h5 class="card-header">Categories</h5>
<div class="card-body">
<div class="row">
<div class="col-lg-6">
<ul class="list-unstyled mb-0">
<li>
Web Design
</li>
<li>
HTML
</li>
<li>
Freebies
</li>
</ul>
</div>
<div class="col-lg-6">
<ul class="list-unstyled mb-0">
<li>
JavaScript
</li>
<li>
CSS
</li>
<li>
Tutorials
</li>
</ul>
</div>
</div>
</div>
</div>
<!-- Side Widget -->
<div class="card my-4">
<h5 class="card-header">Side Widget</h5>
<div class="card-body">
You can put anything you want inside of these side widgets. They are easy to use, and feature the new Bootstrap 4 card containers!
</div>
</div>
{% endblock %}
I have tried tweaking but nothing seems to work
I want the page like this:
|*****************************|
|navigationbar |
|*****************************|
|Post1(Col1-Col8) |SIDEWIDGET|
|***** | |
|Post2(Col1-Col8) | |
|***** | |
|PostN(Col1-Col8) | |
|*****************************|
|Footer |

Answer 1

Your code should work. The col-lg-* modifier applies only for screens that are over 1200px wide as per bootstrap's documentation. Maybe you're using a smaller screen and you also need to add the col-sm and col-md modifiers. Please try those and let me know if it works.
<div class="container">
<div class="row">
<div class="col-sm-8 col-lg-8 ">
{% block content %}
{% endblock %}
</div>
<div class="col-sm-4 col-lg-4">
{% block sidewidget %}
{% endblock %}
</div>
</div>
</div>

Answer 2

you can't use a bootstarp grid system for it because the sidewidget is going to take up the column of the whole three rows .You would have to use flex box for it. by using grid system columns can be individually used in different rows but you cannot have a whole column spanning over the different rows .

Answer 3

In the 'nav' section the 'nav' tag is not closed </nav>. close it and try again.
I think that will solve your problem.
<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
<div class="container">
<a class="navbar-brand" href="#">Start Bootstrap</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Services</a>
</li>
{% if user.is_authenticated %}
<li class="nav-item">
<a class="nav-link" href="{% url 'add' %}">Add Article</a>
</li>
{% endif %}
</ul>
</div>
</div>
</nav>
