“Box-shadow generator” tool not loading properly, making the tools unusable

MDN URL

https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Backgrounds_and_Borders/Box-shadow_generator

What specific section or headline is this issue about?

The generator is not loading properly. Box Shadow Generator App rendered unusable.

What information was incorrect, unhelpful, or incomplete?

The color selector covers 50% of the setting options and the CSS code detail - so the generator app is not usable.

I thought it might be browser specific. I originally loaded the page in Firefox. I next tried loading the page in Safari and the same thing happened.

What did you expect to see?

I expected to see an app that could better help me understand box shadows in CSS.

Do you have any supporting links, references, or citations?
