Formattering af form text field

hvorfor stiller denne style kun background color på mit text field:

.fields {
    background-color: #ffffff;
    padding-right: 3;
    padding-left: 3;
    border-style: solid;
    border-width: 1px;
    border-color: #666666;
    font-size: 6px;
    color: #000000;
    width: 160;
    height: 10;
}

text field:

                <td><input name="Email" type="text" class="fieldSmall" id="Email" onblur="if(this.value=='')this.value=this.defaultValue" onChange="document.tilmeldForm.Email.value=document.inputForm.Email.value;document.frameldForm.email.value=document.inputForm.Email.value" onclick="if(this.value==this.defaultValue)this.value=''" value="Email"></td>
