Challenge task 2 of 2 Using .cake as your context, convert the margins on .filling from pixels to percentages.

10px / 640px = 0.015625 (Move The Decimal Over 2 Spaces)

From 0.015625 To 1.5625

<!DOCTYPE html>

      /* 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: 10px;

Its a rounding thing.

Try 1.563 if that does not work try the entire number.
