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.

CodePudding user response：

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; } 
    
 }

CodePudding user response：

I checked your CSS and found one additional semi-column which isn't required, as well as the invalid properties 'font: size 14rem;' which should be 'font-size: 14rem;' like this.

Please check the updated CSS and let me know if there are any issues.

Note: Indentation should be proper, and unnecessarily high spacing and white space should be avoid.
