[Plugin: Contact Form 7] Resize widht of text box

Hi guys,

I have a contact form display in two columns, however the second column includes a message box that is not showing its right side line because the contact form doesn’t fit in the page widht.

I’d like to reduce the text box widht (not message box), how can I do it?

Thanks!
