Challenge: Decrease the Opacity of an Element

Link to the challenge:
https://www.freecodecamp.org/learn/responsive-web-design/applied-visual-design/decrease-the-opacity-of-an-element

Remove the ` characters around opacity: 0.7;

You don’t need the backticks around opacity: 0.7; when you’re on the freeCodeCamp editor. But interestingly, I’m also not able to pass the challenge after removing the backticks, on Safari. It works on Chrome though.

What browser are you on?

I’m on Safari. I’ll try Chrome. Thank you.
