How do I change the word wrap on the questions on my form?

I can't find an option to change the word wrapping formatting on the questions on my form.

Are you referring to the Question Labels or to the Text tool?

Please provide more details about the issue you are having so that we can assist you properly. If possible, please provide a screenshot.

Thank you for your cooperation.

The question label

It is possible to format the question label using CSS. 

Like this (to break a long word):

.form-label.form-label-top {
    word-wrap: break-word;
}

Or like this (to break at allowed break points):

.form-label.form-label-top {
    word-wrap: normal;
}

Hope that helps
