title: Change the width of form elements created with ModelForm in Django
body: <p>How can I change the width of a textarea form element if I used ModelForm to create it?</p>
  
  <p>Here is my product class:</p>
  
  <pre><code>class ProductForm(ModelForm):
      long_desc = forms.CharField(widget=forms.Textarea)
      short_desc = forms.CharField(widget=forms.Textarea)
      class Meta:
          model = Product
  </code></pre>
  
  <p>And the template code...</p>
  
  <pre><code>{% for f in form %}
      {{ f.name }}:{{ f }}
  {% endfor %}
  </code></pre>
  
  <p><code>f</code> is the actual form element...</p>
