Formula for converting pixels to percentages

I used the cake container measurement of 640 (context) divided it by 10 for 1.56% but it’s not correct?

Using .cake as your context, convert the margins on .filling from pixels to percentages.

<!DOCTYPE html>
<html>
  <head>
    <style>

      /* When setting flexible margin on an element, your context is the width of the element's container.
      When setting flexible padding on an element, your context is the width of the element itself. */

      p {
        margin: 0;
      }
      body {
        color: #fff;
      }
      .container {
        max-width: 800px;
      }

      .icing {
        background-color: #B4C34F;
        width: 100%; /*800px*/
        padding: 10px;
      }
      .cake {
        background-color: #f8748f;
        width: 80%; /*640px*/
        margin: 1.25%;
        padding: 10px;
      }
      .filling {
        background-color: #4FB69F;
        width: 75%; /*480px*/
        margin: 1.56%;
        padding: 10px;
       }
    </style>
  </head>

10/640 = 1.5625%

You may need to be more specific.

Hi Paula,

The following code worked for me. Maybe refresh the browser page?

Jeff

.filling {
        background-color: #4FB69F;
        width: 75%; /*480px*/
        margin: 1.5625%;
        padding: 10px;
       }
