SVG at a data URI for background images.... just because you can, doesn't mean you should.

Why is my CSS broken after implementing the namespaces I showed above? The namespaces can only be resolved within your CSS when you add @namespace declarations corresponding to your XML namespaces. This is described in the spec. Make sure your stylesheet has the following statement, placed at an appropriate location (directly after all @charsets and @imports): @namespace active 'http://www.xxx.com/tracks/active'; If you have styles for the rest of your namespaces, you'll need to include those as well: @namespace completed 'http://www.xxx.com/tracks/completed'; @namespace inactive 'http://www.xxx.com/tracks/inactive';

What is the use of @namespace in CSS?
