3 Spalten Layout in einem mittig zentrierten div

[Sanjoy]

Vielen Dank schon mal...also aktuelle Korrektur:
DIV.div_for_message {
 border: 1px solid #999;
 background-color: red;
 width: 50%;
 height: 200px;
 margin: 20px 25%;
 position: relative;
}

DIV.div_for_message DIV#div_message_left {
 background-color: blue;
 height: 150px;
 width: 20px;
 position: absolute;
 left: 0;

}

DIV.div_for_message DIV#div_message_middle {
 background-color: #ffc;
 height: 150px;
 margin: 0 20px;

}

DIV.div_for_message DIV#div_message_right {
 background-color: blue;
 height: 150px;
 width:20px;
 position: absolute;
 right: 0;
}

Gute oder schlechte Lösung?

Lieben Gruß
