how to fix the Error at-rule or selector expected

Issue

I'm getting an error where it says "at-rule or selector expected" I've tried putting a semi-colon at the end but it wont work. Please do recommend some suggestions for me as I don't know what to do. I have tried checking my code over and over for any CSS errors but there doesn't seem to be any, so I really don't know what's wrong here.

Solution

You have an additional } Replace this :

 @media (max-width: 600px) {
    
    
      .footer {width: 100%;  text-align: center; } }
    
    }//error happens here

with this :

 @media (max-width: 600px) {
    
    
      .footer {width: 100%;  text-align: center; } 
    
 }
