Impossible to style a textarea generated by a WordPress contact form plugin!

In this page, I’m trying to style a textarea generated by Contact Form 7, but it doesn’t matter what I do I can’t.

code:

CSS:

.wpcf7-form input, #wpcf7-form textarea {
    border-color: #808080 #C0C0C0 #C0C0C0 #D4D4D4;
    border-style: solid;
    border-width: 1px;
    margin: 0 400px 10px 0;
    padding: 5px;
    width: 350px;
}
#wpcf7-form textarea {
    margin: 0 400px 20px 0;
}

HTML:

                <div class="wpcf7" id="wpcf7-f1-p2-o1"><form action="/wordpress/?page_id=2#wpcf7-f1-p2-o1" method="post" class="wpcf7-form">
