CSS VALIDATOR COMMENT

Hi!

Here is my style sheet, included in my XHTML code:

<style type="text/css">
 body {
    background-image: url("fond.png");
 }
 #t1 {
    background-color: #e12327;
    width: 90%;
    height: 190%;
    position: absolute;
    top: 35px;
    left: 50px;
    border: ridge;
 }
 #t2 {
    background-color: #15d014;
    width: 80%;
    height: 170%;
    position: absolute;
    top: 5em;
    left:6em;
    border: ridge;
}
#t3 {
    background-color: blue;
    width: 74%;
    height: 160%;
    position: absolute;
    top: 7em;
    left:8em;
    border: ridge;
}
#t4 {
    padding-top: 4em;
}
p {
    padding-top: 3em;
    padding-left: 5em;
    text-align: center;
    font-family: Arial;
    color: white;
    font-size: 20px;
}
    </style>

and here is the Validator comment:


        URI : file://localhost/TextArea

	Lexical error at line 1, column 2. Encountered: "s" (115), after : "<"


What does it mean ?

Thank you very much.
