Introduces cascading variables as a new primitive value type that is accepted by all CSS properties, and custom properties for defining them.
CSS Custom Properties are included in Edge 15, which shipped today (11th April) with Windows 10 Creators Update.

Info about that feature? When in stable release?
Jouni Koivuviita commented
Awesome to see this already in the preview build!
When can we expect it to included in a stable release update?
Last I checked, Edge's CSS variables didn't work with SVG use content--even the fallback syntax was broken.
For more info, see:
Looking forward for the full support.
Currently, Microsoft Edge completely ignored by the project.

Great, looking forward for more surprises. I was going to use CSS Variables into my site but because of this, I stopped myself :)
can we dump ie11 yet?
Miyabi Igarashi commented
Is this full support or partial support? I remembered the last time I've seen was only partial support.
ASAP! Do it man! Don't hesitate!!!!
Shamez Rajan commented
Thanks - we need it
Lets see these variables implemented!!
Michal Kovařík commented
Please please ship it with Creators Update. Don't let us wait another year since Edge cannot be updates as often as Chrome.
How do you target IE 13.0 only using CSS?
Matt Coady commented
Yessss! Can finally implement this into our product.
Please make sure it works with SVG properties :-)

Hurry up Microsoft!

Also, please make sure that programmatic updates to custom variables trigger style recalculations not only on elements and their children, but their *pseudo*-elements as well. For example, this codepen (http://codepen.io/traviskaufman/pen/jARYOR) does not work in Safari 9.1 because of this problem (fixed in 10 and TP) :)
