body: <p>How can I add multiple attributes to an input tag in Django ?</p>
  
  <p>Example: For adding a single attribute I can use this code</p>
  
  <pre><code>email = forms.EmailField(
          widget = forms.TextInput(attrs={'placeholder': 'Email'}))
  </code></pre>
  
  <p>But if I want to add 'class', 'size' and 'placeholder' attributes then what is the way of doing it in django forms? </p>
