Change custom field size (text field width) under custom tabs.

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

By default no size is applied. You can force a size on the input using the Size parameter when editing the field in CB > Field Management. If that doesn't work then it's CSS from your template doing it. You can also apply custom CSS classes to a fields container div within CB > Field Management while editing the field. You can then style your custom classes as needed.
