The input size of the fields is fixed.
Although textarea fields can be resized verticaly, the width is fixed to 140 px.

How can I change the width of the text input field.
And how can I change the width of the textarea field.

I think that this css will do the trick.
But where can I add custom css to CB?
.cb_template textarea {width: 70%;}
.cb_template input[type="text"] {width: 70%;}

Thanks,
Patrick
