Note

To work as intended, your CSS style sheet needs a correct document parse tree. This means you should use <a href="http://validator.w3.org/">valid HTML</a>.

If you want to validate your CSS style sheet embedded in an (X)HTML document, you should first <a href="http://validator.w3.org/">check that the (X)HTML you use is valid</a>

Address of page to Validate

The @charset rule may only occur at the start of the style sheet. Please check that there are no spaces before it.

This profile has a very specific syntax for @charset: @charset followed by exactly one space, followed by the name of the encoding in quotes, followed immediately by a semicolon.

In CSS1, a class name can start with a digit (".55ft"), unless it is a dimension (".55in").

In CSS1, an id name can start with a digit ("#55ft"), unless it is a dimension ("#55in").

In CSS1, a class name could start with a digit (".55ft"), unless it was a dimension (".55in"). In CSS2, such classes are parsed as unknown dimensions (to allow for future additions of new units) To make ".%s" a valid class, CSS2 requires the first digit to be escaped ".3%s"
