MattiaParla on "[Plugin: Contact Form 7] how stretch box"

Hi to everyone,
is it possible stretch the boxes of text fields?

<p><font color="666666">Nome*</font>
[text* your-name] </p>

<p><font color="666666">E-mail*</font>
[email* your-email] </p>

<p><font color="666666">Oggetto*</font>
[text your-subject] </p>

<p><font color="666666">Messaggio*</font>
[textarea your-message] </p>

Thank you in advanced.
M
