Expected RBRACE and Unexpected token '}'

Question

I am trying to edit a post's CSS in Wordpress theme editor, however, I get two errors. Here is the code:

#post-6303 {
  .post-content {
    padding: 0 10% 0 10%;
  }
}

The second line gets unexpected RBRACE and the last line gets unexpected '}'

Any ideas?

Answer 1

It is invalid syntax if you use css without any preprocessors.

There is valid code:

#post-6303 .post-content {
  padding: 0 10% 0 10%;
}
