You can change the look of this form by creating CSS rules for the <form>, <input>, <textarea>, and <select> tags. You can use the next file for example:

File test.cssform {

border: 1px dotted #aaaaaa;

padding: 3px 6px 3px 6px;

}input {

color: #00008B;

background-color: #FFFFCC;

border: 1px solid #FFCC00;

}select {

width: 100px;

color: #00008B;

background-color: #FFFFCC;

border: 1px solid #FFCC00;

}textarea {

width: 200px;

height: 40px;

color: #00008B;

background-color: #FFFFCC;

border: 1px solid #FFCC00;

}
