After landing in Firefox and WebKit, canvas blend modes are now available in Chrome Canary!
Here’s what you need to do check out the feature in your favorite browser:
For Firefox, canvas blend modes are enabled by default in the stable version, so there are no prerequisite steps for enabling canvas blend modes.
For WebKit, simply download one of the nightly builds from http://nightly.webkit.org.
Once you’ve completed these steps, navigate to this codepen to see canvas blending at work!
