Hi Ronald,

You're almost there, you just need another 0 in there for it be interpreted correctly.

When three values are given they are interpreted as offset-x, offset-y, and blur-radius in that order. This means your code produces these values:

  • offset-x: 0
  • offset-y: 60px
  • blur-radius: 5px

The goal is have both vertical and horizontal offsets at 0, a blur-radius of 60px, and a spread-radius of 5px. To accomplish that you'll need four values:

.main-header {
  box-shadow: 0 2px 15px #aaa, inset 0 0 60px 5px firebrick;

You can check out some useful syntax examples in the MDN documentation for box-shadow.

Hope this helps! Let me know if you have any questions.
