Contact Form 7 problem

hey all (sorry about my english, not native speaker)

so i’m using this CSS to give some color to my contact form.

div.wpcf7-mail-sent-ok {
	border: 2px solid ##000000;
}
input[type=text], input[type=email], textarea
.wpcf7-form input, textarea {
    border: 1px solid #999999;
    height: 26px;
}
   input[type=yourmessage],
wpcf7-form input, textarea {
    border: 1px solid #999999;
    height: 26px;
.wpcf7-form input[type="submit"] {
   background-color: #8CD4CF;
   border: medium none;
   color: #FFFFFF;
   cursor: pointer;
   height: 30px;
     input[type=yourmessage],
wpcf7-form input, textarea {
    border: 1px solid #999999;
    height: 26px;
