Komme nicht mit CSS klar

[Pyrus]

versuch's mal mit:

	body {
	
	background-color:b6e026;
	margin: 0 auto;
} 

div.main {
margin: 0 auto;
background-color:b6e026;
width: 714;


}

div.left {
background-image: url(pictures/left.jpg);
background-color:white;
width: 162px;
float: left;
margin: 0 auto;
height:100%;

}

div.right {
bbackground-image: url(pictures/right.jpg);
background-color:white;
float: left;
width: 552px;
height:100%;
}

have a nice day
