A site's background management is a part of the maintenance of fixed position, editable part of the changes with the browser changes, so sometimes use the frame framework to implement this form, the author is not using the frame but the pure div layout, want to achieve this way how to do it? The following control div implementation of the left-right, fixed to the left, the right-hand side with the browser changes and changes in the jquery implementation code.

The code is as follows: <script type= "Text/javascript" >//Resize the left and right layout based on browser size $ (window). Ready (function () {var wheight=$ (window).  Height ();  var wwidth=$ (window). width ();  $ (". Div_admin_left"). CSS ("height", (wheight-40));  $ (". Div_admin_right"). CSS ("height", (wheight-40));  $ (". Div_admin_right"). CSS ("width", (wwidth-285) + ' px ');  });  $ (window). Resize (function () {var wheight=$ (window). Height ();  var wwidth=$ (window). width ();  $ (". Div_admin_left"). CSS ("height", (wheight-40));  $ (". Div_admin_right"). CSS ("height", (wheight-40));  $ (". Div_admin_right"). CSS ("width", (wwidth-285) + ' px ');  }); </script> here the author made the left fixed, the right with the browser changes in the way, but also implemented with the browser to become larger and larger, shrinking also relative should be proportional to shrink the code, for reference only.
