hi guys, any one can give an idea for this problem.. i had this code..
Code:
         <STYLE type="text/css" media="screen">
     
       div#fixtop
         {
         margin-top:400px;
         position:fixed;
         }
         </style>
and call this one on html like this
Code:
   
     <div id="fixtop" >
   
      <A href="#pagetop">Page Top </A>
   
      </div>
above code works fine..but if i change the margin-top to 600px the text is not displayed on the screen.. any ideas for this? why if the margin-top value is increased text is not visible... thanks..
