Use the content div as your container for the page.

 .sidebar {
     position: fixed;
     width: 200px;
     height: 400px;
     background: #000;
 }
 .content {
     margin-left: 200px;
     height: 500px;
     width: auto;
     position: relative;
     background: #f00;
     overflow: auto;
     z-index: 1;
 }
 .info {
     width: 1440px;
     height: 300px;
     position: relative;
     background: #f55;
 }



    

Your content will need to be the container to put the page in. The values here are my test to see if I am correct in this. If your width and height exceeds the values you set for content, the scroll bars will appear.

edit: responsive sidebar

To have a responsive fixed sidebar, simply add a media-query.

Example:

@media (min-width:600px) {
   .sidebar {
     width: 250px;
   }
   .content {
     margin-left: 250px;
   }
 }
