I am working on a web app and need it to be compatible with mobile devices.
The web app is written using Django, I am using Bootstrap 5 for arranging the page to be responsive. I am totally a newbie with mobile frontend development.
Now I understand that the grid system could help us scale the whole page to fit mobile devices properly. But as the page is developed using desktop, when viewing in mobile devices, the elements in the page is so small. I was originally thinking that Bootstrap would magically enlarge each row when it scale to fit mobile devices, but that's not the case.
Consulting with my friends, we seem to need to manually set size (width * height) based on the device-width. Then that's a lot of work. Is this the only way to go?
The page does scale to fit mobile devices, but each card is so small that it is very difficult to see the text/button.

I'm trying to make responsive blog post. Everything works fine, but I don't like the way it looks. I would like to have a solution when my blog post with image itself would be centered. On desktop version it is less visible, but on mobile device it looks ugly... I'm currently using bootstrap 4, but if you got solutions with css, I also would be really happy!
I need something like on the image:
Desktop version
Mobile version
Here is my html + bootstrap model:
{% extends 'blog/base.html' %}
{% block content %}
<article class="media content-section">
<img class="rounded-circle article-img" src="{{ object.author.profile.image.url }}" alt="">
<div class="media-body">
<div class="article-metadata">
<a class="mr-2 author_title" href="{% url 'user-posts' object.author.username %}">#{{ object.author }}</a>
<small class="text-muted">{{ object.date_posted|date:"N d, Y" }}</small>
<div>
<!-- category section -->
<small class="text-muted">
Categories:
{% for category in post.categories.all %}
<a href="{% url 'blog_category' category.name %}">
{{ category.name }}
</a>
{% endfor %}
</small>
</div>
{% if object.author == user %}
<div>
<a class='btn btn-secondary btn-sm mt-1 mb-1' href="{% url 'post-update' object.id %}">Update</a>
<a class='btn btn-danger btn-sm mt-1 mb-1' href="{% url 'post-delete' object.id %}">Delete</a>
</div>
{% endif %}
</div>
<img class="img-fluid center" id="rcorners3" src="{{ object.image.url }}" alt="none">
<h2 class="article-title text-center">{{ object.title }}</h2>
<p class="article-content">{{ object.content }}</p>
</div>
</article>
{% endblock content %}
And some code from base.html block:
<main role="main" class="container">
<div class="row">
<div class="col-md-8">
{% if messages %}
{% for message in messages %}
<div class="alert alert-{{ message.tags }}"> <!--grabbing bootstrap tag for displaying alert, info etc. -->
{{ message }}
</div>
{% endfor %}
{% endif %}
{% block content %}{% endblock %}
</div>
<div class="col-md-4">
<div class="content-section">
<h3>Sidebar</h3>
<p class='text-muted'>Explore smth new today!
<ul class="list-group article-metadata">
<li class="list-group-item list-group-item-light"><a class="author_title" href="{% url 'blog-home' %}">Latest Posts</a></li>
<li class="list-group-item list-group-item-light"><a class="author_title" href="">Links</a></li>
<li class="list-group-item list-group-item-light">Calendars</li>
<li class="list-group-item list-group-item-light">etc</li>
</ul>
</p>
</div>
</div>
</div>
</main>
Finally, I solved this solution like this:
{% extends 'blog/base.html' %}
{% block content %}
<article class="media content-section">
<img class="rounded-circle article-img" src="{{ object.author.profile.image.url }}" alt="">
<div class="article-metadata">

<small class="text-muted">{{ object.date_posted|date:"N d, Y" }}</small>
<div>
<!-- category section -->
<small class="text-muted">
Categories:
{% for category in post.categories.all %}
<a href="{% url 'blog_category' category.name %}">
{{ category.name }}
</a>
{% endfor %}
</small>
</div>
{% if object.author == user %}
<div>
<a class='btn btn-secondary btn-sm mt-1 mb-1' href="{% url 'post-update' object.slug %}">Update</a>
<a class='btn btn-danger btn-sm mt-1 mb-1' href="{% url 'post-delete' object.slug %}">Delete</a>
</div>
{% endif %}
</div>
</article>
<article class="media content-section">
<div class="media-body">
<img class="img-fluid center" id="rcorners3" src="{{ object.image.url }}" alt="none">
<h2 class="article-title text-center">{{ object.title }}</h2>
<p class="article-content">{{ object.content }}</p>
</div>
</article>
{% endblock content %}
I'm looking for a way to add a class, which I could modify in css, to images and videos in both editor forms and html templates displaying the form. I'm using the SummernoteInplaceWidget() from django-summernote package and it's working fine except this feature.
I use bootstrap 4 with it.
Any ideas?
Thanks in advance.
forms.py:
from django.forms import ModelForm
from django_summernote.widgets import SummernoteInplaceWidget
from .models import Post
class PostFormModel(ModelForm):
class Meta:
model = Post
fields = ['title', 'content', 'image', ]
widgets = {
'content': SummernoteInplaceWidget(attrs={'class': 'summer-img-class'}),
}
post_form.html:
{% extends "blog/base.html" %}
{% load crispy_forms_tags %}
{% block mt %} mt-2 {% endblock mt %}
{% block content %}
<div class="content-section">
<form method="POST" enctype="multipart/form-data">
{% csrf_token %}
<fieldset class="form-group">
<legend class="border-bottom mb-4">Blog Post</legend>
{{ form|crispy }}
{% if form.image.errors %}
<div class="alert alert-danger">
{{ form.image.errors }}
</div>
{% endif %}
</fieldset>
<div class="form-group">
<button class="btn btn-outline-info" type="submit">Post</button>
</div>
</form>
{% block jquery %}
{{ form.media }}
{% endblock %}
</div>
{% endblock content %}
post_detail.html:

</div>
<div class="col-md-9 col-sm-9 col-9">
<div class="article-metadata">

{% if object.author == user %}
<div>
<a class="btn btn-secondary btn-sm mt-1 mb-1" href="{% url 'post-update' object.id %}">Update</a>
<a class="btn btn-danger btn-sm mt-1 mb-1" href="{% url 'post-delete' object.id %}">Delete</a>
</div>
{% endif %}
</div>
<h2><a class="article-title" href="{% url 'post-detail' post.id %}">{{ object.title }}</a></h2>
</div>
<div class="row media-body pt-3">
<div class="col-md-12">
{% if post.image %}
<img alt="" src="{{ object.image.large.url }}" class="post_image rounded mx-auto mb-2 d-block"/>
{% endif %}
<p class="article-content ml-3">{{ object.content|safe }}</p>
</div>
</div>
</div>
</article>
{% endblock content %}
I tried to add some styling to .article-content, it didn't have any effect, the same for this class in css (I imagine it can be more effectively):
.summer-img-class * {
max-width: 100%;
max-height: 400px;
object-fit: cover;
margin: auto;
}
Maybe it should be done with Jquery somehow, I don't know.
I'm having a problem using Twig because I have a vertical sidebar used as a menu. When the user clicked on the menu item, it add an active class. But when the user change of page, active page disapear. I know this is the behavior expected but that's what I'm here. I wanted to know if someone have an idea to keep this active class in my layout when the user click on this item, so that, when he change of page, the menu will be as he desired (i.e. active or not)
Here is my layout.html.twig file :

The sidebar is inside the {% block navbar %}.
Thanks all in advance.
You can use twig's if inside the class definition of each menu item.
If the current path matches the menu item's path, then print " active " inside the class html attribute.
I found the solution with one of my teamates. I used javascript and jquery to set cookies for the menu. And then if the cookie is set i add/remove the class for my menu. Thanks all by the way.
I have a calendar generated by Django and styled with Bootstrap.
Here is the code in the Django template :
<div class="content">
{% for month in period.get_months %}
<div class="col-md-3">
<div class="row row-centered">
<button class="btn btn-custom active" href="{% url "month_calendar" calendar.slug %}{% querystring_for_date month.start 2 %}">{{month.name}}</button>
</div>
<div>
{% month_table calendar month "small" %}
</div>
</div>
{% endfor %}
</div>
Now, since months have a different number of weeks they have different heights I would like to avoid something like this:
I understand from this answer that the best solution would be to use a clearfix.
So, how can I modify the for loop in my template so that Django inserts an extra line <div class="clearfix"></div> every four items?
Django templates for loop store current index in forloop.counter variable. You can read about this in docs. So you can try to change you code like this:
<div class="content">
{% for month in period.get_months %}
<div class="col-md-3">
<div class="row row-centered">
<button class="btn btn-custom active" href="{% url "month_calendar" calendar.slug %}{% querystring_for_date month.start 2 %}">{{month.name}}</button>
</div>
<div>
{% month_table calendar month "small" %}
</div>
</div>
{% if forloop.counter|divisibleby:4 %}
<div class="clearfix"></div>
{% endif %}
{% endfor %}
</div>
I am very new to web development and Django. I am following a tutorial called "Try Django 1.8".
In this code I am supposed to change the background-color of jumbotron to #155A1E.
If I press shift + refresh in google chrome, the color shows up then it changes back to gray. When I inspect the code in google chrome, I can see in the styles tab that the background-color in the .jumbotron{} has a strike-through. Also there is another verion of .jumbotron{} in the styles tab that has a background-color and has a check. If I uncheck the box, the color gets fixed.
How can I fix this in Django?
{% extends "base.html" %}
{% load crispy_forms_tags %}
{% block head_title %}Welcome | {{ block.super}}{% endblock %}
<style>
{% block style %}
.jumbotron {
background-color: #155A1E;
}
{% endblock %}
</style>
{% block jumbotron %}
<div class="jumbotron">
<div class='container'>
<div class="row">
<div class='col-sm-6'>
<h1>Try Django 1.8</h1>
<p>Some text here!!! This text should be long so that we can test the columns in the webpage. So here we go. We are trying to make this line as long as possible.</p>

You can add do important to your css attribute.
Just like that:
.jumbotron {
background-color: #155A1E!important;
}
It will be taken instead of the default one
It may be very late to answer the question but could help someone who is doing the tutorial now as myself.
Problem is your style should come under the
{% block jumbotron %}
otherwise its never been executed.
Here it is
{% block jumbotron %}
<style>
{% block style %}
.jumbotron {
background-color : #1e78d2 !important;
}
{% endblock %}
</style>
<div class="jumbotron">
<div class="container">....... {% endblock %}
Hope it helps someone
Makesure source of bootstrap is before your style source, and example:
<link href="{% static 'css/bootstrap.min.css' %}" rel="stylesheet" media="all">
<link href="{% static 'css/your_style.css' %}" rel="stylesheet" media="all">
