W3C CSS3 Specification Compatibility

Media

Less4j correctly translates all media queries conforming to css3 specification.

Test Case:

• W3CMediaTests

Links:

• W3c specification: http://www.w3.org/TR/css3-mediaqueries/
• W3c test cases: http://www.w3.org/Style/CSS/Test/MediaQueries/20120229/

Selectors

Less4j correctly translates almost all selectors conforming to css3 specification. Namespaces are the only missing feature. Anything else is expected to work correctly.

Two types of w3c tests are skipped:

• those with namespaces,
• those that crashes less.js.

Test Case:

• W3CSelectorsTests

Links:

• W3c specification: http://www.w3.org/TR/css3-selectors/
• W3c test cases: http://www.w3.org/Style/CSS/Test/CSS3/Selectors/current/

@keyframes Animations

Less4j translates CSS3 @keyframes Animations.

Test Case:

• Since w3c did not released test cases for this, the test case is part of basic StrictComplianceTest CSS compatibility test.

• W3c specification: http://www.w3.org/TR/css3-animations/
• W3c test cases: not available yet

Paged Media

Less4j translates CSS3 Paged Media.

Test Case:

• Since w3c did not released test suite and specification is not finished yet, we created test cases from examples in the CSS Paged Media Module Level 3 Editor's Draft 28 November 2012 version of the specification.
