You should not have a comma after the final selector.
You have mistyped text-align (and it is usual to include a semi-colon after the property value).
You have two closing curly braces when you should have only one.
If you fix these issues, your code will pass.
Also, it’s important to develop good formatting habits, as it makes code much easier to read and to debug. The example given in the instructions shows how a properly formatted selector and property/value pair should look. The principles of good formatting apply whether you’re writing HTML, CSS or any other language.
