Define css class in django Forms

Assume I have a form

class SampleClass(forms.Form):
    name = forms.CharField(max_length=30)
    age = forms.IntegerField()
    django_hacker = forms.BooleanField(required=False)

Is there a way for me to define css classes on each field such that I can then use jQuery based on class in my rendered page?

I was hoping not to have to manually build the form.
