Counter styles

Back to the index.

Counter styles specification.

Counter styles are a more generalized way of defining what kind of markers your lists use. The traditional values remain supported, but in addition there’s a new, generic way of describing list counters.

Not yet supported

I don’t yet have tests for all declarations and rules in the spec. I will extend these tests once @counter-style is supported.

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

MacBook Pro 17'' with OS 10.9.4
This is my main test station. It also runs all virtual Windows systems.
All downloaded from 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.
Microsoft Surface with Windows RT 8.1
Ubuntu 12.04 on pretty old hardware. Not fair for performance comparisons.
