Question

I tried this JavaScript code:

    dx = document.getElementById('box').style
    
    dx.backgroundColor= '#fff' 
    dx.visibility = "visible";
    dx.width = 800 + "px" ;
    dx.height = 40 + "px" ;
    dx.top = 600 + "px" ;
    dx.overflow = "hidden" ;
    dx.marginLeft = "-400px";

    tab = "<table width='800' border='0' cellpadding='1' > <tr> <td width='75' ></td> <td width='200'></td> <td width='75' ></td> <td ></td>  </tr>  <tr> <td align='left' valign='middle'><div align='right'>Contact</div></td> <td colspan='4' align='left' valign='middle'><input name='Pcontact' type='text' id='Pcontact' size='20' /> Number <input name='Pnumber' type='text' id='Pnumber' size='20' /> Mail <input name='Pmail' type='text' id='Pmail' size='25' /> <input name='addcontact' type='button' id='addcontact' value='Add Contact'  /></td> </tr> </table>" ;
    
    document.getElementById('box').innerHTML = tab 

    dx.opacity = 10 ;

and this CSS for the box element:

#box {
    position:fixed;
    width: 600px;
    height: 700px;
    top: 40px ; 
    border: 2px solid black;
    background-color:#CCC; 
    left:50% ; 
    margin-left:-300px;
    visibility:hidden ;
    overflow:scroll ; 
} 

I expected this to reduce the opacity, but it seems to have no effect. What is wrong, and how do I fix it?

Answer 1

opacity has a range of 0 to 1, you are setting it to 10.

You probably mean 0.1 or perhaps 0.9.
