2 col

[windows]

how do i make 2 rows next to each other.

one needs to be 500px and one needs to be 200px.

this is what i have at the moment but it is wrong.

#content{
width:500px;
margin:auto;
padding-right:200px;
text-align: justify;
}

#contentright{
width:200px;
margin:auto;
padding-right:0px;
text-align: justify;
float:right;
}Add float:left; to #content
