perhaps try changing:
#outerWrapper #contentWrapper #content {
margin: 0 0 0 220px; /* Sets the margin properties for an element using shorthand notation (top, right, bottom, left) */
padding: 10px 10px 10px 10px; /* Sets the padding properties for an element using shorthand notation (top, right, bottom, left) */
}
to:
#outerWrapper #contentWrapper #content {
margin: 0 0 0 220px; /* Sets the margin properties for an element using shorthand notation (top, right, bottom, left) */
padding: 10px 10px 10px 10px; /* Sets the padding properties for an element using shorthand notation (top, right, bottom, left) */
overflow: hidden;
}
