How to increase the size of the booleanfield in flask form?

Question

I am making a flask form that contains multiple checkbox. I have this code in the form.py file.

var_name = BooleanField('', default=False)

And I have this in the html.

{{ var_name }}

The checkbox that I get on the browser is too small. I guess it is the default size. How do I increase the size of the checkbox? Thank you

What you can do is, using a hint taken from the WTForms docs here, is add a class to the field::

var_name(class_ = "checkbox")

Then style it with CSS:

.checkbox {
    height: 25px;
    width: 25px;
}
