But widget tweaks form-control wasn't working.

My code is like this

{% load widget_tweaks %}

{% block title %}Start a New Topic{% endblock %}

{% block breadcrumb %}
  <li class="breadcrumb-item"><a href="{% url 'home' %}">Boards</a></li>
  <li class="breadcrumb-item"><a href="{% url 'board_topics' board.pk %}">{{ board.name }}</a></li>
  <li class="breadcrumb-item active">New topic</li>
{% endblock %}

{% block content %}
  <form method="post" novalidate>
    {% csrf_token %}

    {% for field in form %}
      <div class="form-group">
        {{ field.label_tag }}

                {% if form.is_bound %}
        {% if field.errors %}

          {% render_field field class="form-control is-invalid" %}
          {% for error in field.errors %}
            <div class="invalid-feedback">
              {{ error }}
            </div>
          {% endfor %}

        {% else %}
          {% render_field field class="form-control is-valid" %}
        {% endif %}
      {% else %}
        {% render_field field class="form-control" %}
      {% endif %}

      {% if field.help_text %}
        <small class="form-text text-muted">
          {{ field.help_text }}
        </small>
      {% endif %}
    </div>

Try using bootstrap or django crispy forms in your form.
