Ensure that the body content is completely transparent upon loading the page, except for a specific div within the content that remains

Currently, I am experimenting with JQuery and my goal is to have the body content of a webpage appear transparent upon loading, with the exception of one specific div that should remain opaque.

So far, this is what I've accomplished ...

<!DOCTYPE html>
<html>
<head>
 <title>JQuery Experiment</title>
 <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js">     </script>
 <script>
  $(document).ready(function(){

      $( "#trans" ).addClass( "getTransparent" );
       $( "#opaq" ).addClass( "getOpaque" );

      });
   </script>
   <style>

   body{

       background-color: #F0FFFF; 
    }
   .myClass{

       height: 100px;
       background-color: #4863A0;

    }
   .getTransparent{

        opacity: 0.3;  

    }
    .getOpaque{

        opacity: 1 !important;

     }
     </style>

 </head>
      <body id="trans">

 <div id="opaq" class="col-md-6 col-md-offset-3 myClass">
 This section should remain completely opaque...
 </div> 

      </body>
 </html>

Upon loading the page, however, it does not produce the desired outcome. Instead, the entire page ends up being transparent, including the specified div that was intended to have an opacity of 1.

What might be missing or need adjustment in order to achieve the desired result?
Any assistance would be greatly appreciated.

Answer №1

The reason this occurs is because the div is nested within the body, causing it to inherit the opacity of 0.3 from its parent.

To achieve the desired result, you can create a structure like this:

<body>
    <div class="transparent"></div>
    <div class="opaque"></div>
</body>

Additionally, make sure to add position: absolute and z-index properties in order for the opaque div to overlay the transparent one.

Answer №2

If you're looking to add a touch of color in your CSS, try this handy hack:

   background-color: rgba(112,45,200,0.5);//#702dc8;
