min-height:calc(100vh-89px); shows error in my style console and I dont know why?

This is the Creating a sticky footer link

So I tried the same code as instructed and I see error message in the console leaving the footer in the middle of the screen with whole lot of space left out at the bottom. I dont know why

@media (min-width: 769px){
  .wrap{
      min-height:calc(100vh-89px);
  }
}

Here is my snapshot

It appears the Styles console wants a space before and after the minus sign.

.wrap {
    min-height: calc(100vh - 89px);
}

You are right! Thank you so much, the issue has been resolved. I always thought the space does not matter in JS, but in this case it does!!!

Hey Tony Shangkuan ! 👋

Did you add the wrapper div with the class of wrap as seen at 1:00 in the video?

I see the same issue until I add that div in there html.
