Contributing to the CSS3 Paged Media

The CSS3 Paged Media Test Suite still needs a lot of work, and the CSS Working Group can't finish it all by itself. Anyone can contribute: here are the guidelines.

How to Contribute a New Test

Template for New Tests

The baseline format for CSS3 Paged Media tests is XHTML 1.1. A set of scripts generate the various formats from this source version.

Copy and paste the following text into a new file, or save this file, and replace the capitalized parts. <link> elements are used to link to the relevant section of the spec. If this file tests one or more specific test assertions, add a <meta> element for each one, copying the assertion directly into its content attribute. A test will generally test many sections and assertions (e.g. every test tests for proper parsing). Only list assertions that the test focuses on: ones that must still be tested in this test even if the test's approach to testing them changes in the future.

If the test does not contain ”@page”, the build scripts will add the following style rules:

  @page { counter-increment: page;
          font: italic 8pt sans-serif;
          color: gray;
          @top-left { content: "CSS 2.1 Conformance Test Suite"; }
          @top-right { content: "Test TEST-FILE-BASE-NAME"; }
          @bottom-right { content: counter(page); }

If the test does contain ”@page”, the build scripts will instead add this information as the first and last paragraphs inside the <body>.

The rel=“author” link is optional.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "">
<html xmlns="">
  <title>CSS Test: DESCRIPTION OF TEST </title>
  <link rel="author" title="NAME OF AUTHOR" href="mailto:EMAIL OR http://CONTACTPAGE"/>
  <link rel="help" href="RELEVANT_SPEC_SECTION"/>
  <meta name="flags" content="TOKENS" />
  <meta name="assert" content="TEST_ASSERTION"/>
  <style type="text/css">
