peedeeboy opened a new pull request #1103: [NETBEANS-1458] Fix for CSS3 perspective property doesn't support pixels value
URL: https://github.com/apache/incubator-netbeans/pull/1103
 
 
   Quick and easy.
   
   Netbeans CSS parser rule for the perspective property is configured as:
   
   none | <number>
   
   and for the perspective() function is configured as:
   
   perspective(<number>)
   
   This appears based on [2009-03-20  W3C 3D-Transformations module CSS spec.](https://www.w3.org/TR/2009/WD-css3-3d-transforms-20090320/#perspective-property) 
   
   In the [2013-11-26 W3C 3D-Transformations module CSS spec](https://www.w3.org/TR/2013/WD-css-transforms-1-20131126/#perspective-property) the perspective property rule was changed to:
   
   none | <length>
   
   and the perspective function changed to:
   
   perspective(<length>)
   
   Although Perspective didn't appear to make it past the draft stage of the 3D transform module spec, it is implemented in browsers as none | <length> and the [W3C CSS validator](https://jigsaw.w3.org/css-validator/) accepts perspective: <length> as valid CSS, so there is a strong argument NB should be updated to match.
   
   To test
   ---------
   
   1. Create a new PHP / HTML project with a CSS file
   2. Copy and paste the following CSS:
   
   .classA {
       perspective: 100;
       transform: perspective(100);
   }
   
   /* perspective: <length> */
   .classB {
       perspective: 100px;
       transform: perspective(100px);
   }
   
   * Before PR: NB will parse classA as valid CSS
   * After PR: NB will parse classB as valid CSS
   
   Check which one is actually valid (classB !) with W3C validator.
   
   HTH :)
