Color

Back to the index.

CSS3 Color specification.

The color module defines some color-related declarations and values. Not terribly exciting, but it has to be done.

Last major update on 7 October 2014.

I'm writing a CSS book.

Tested browsers

Desktop browser test array 2.0.1; September 2014

IE7 and lower
I removed them, so they’re not tested for newer methods and properties that they don’t support anyway. However, I copy all information from older versions of the Tables.
If IE8 supports a method or property I never tested before I have to guess if IE7 and lower also support it. In general I assume they support the Microsoft-invented properties, but for others I will occasionally have to add a "Don’t know" entry. If IE8 does not support something I never tested before, I assume IE7 and lower also don’t support it.

Operating systems

Mac
MacBook Pro 17'' with OS 10.9.4
This is my main test station. It also runs all virtual Windows systems.
Windows
All downloaded from modern.ie. I use VirtualBox, and downloded the Windows 7 systems for all browsers but IE11, which runs on Windows 8.1.
The non-IE Windows browsers all run on the IE9/Win7 virtualization.
Surface
Microsoft Surface with Windows RT 8.1
Linux
Ubuntu 12.04 on pretty old hardware. Not fair for performance comparisons.
