normal
Practical Application № 1:
Monochromatic Color-Tinted Images
(Luminosity - Live coding FTW!)
Practical Application № 2:
Automatic Text Contrast
(Difference)
Testing for support:
Modernizr.addTest("mix-blend-mode", function(){
return Modernizr.testProp("mixBlendMode");
});if ("CSS" in window && "supports" in window.CSS) {
var support = window.CSS.supports("mix-blend-mode","difference");
support = support?"mix-blend-mode":"no-mix-blend-mode";
document.documentElement.className += support;
}@supports (mix-blend-mode: difference) {
}Practical Application № 3:
Cross-Browser Text Masks
(Darken / Lighten)
Practical Application № 4:
Better Backgrounds & Overlays
(All modes)
Blend modes:
- Exemplars of progressive enhancement, when coded well.
- Reduce re-work
- Can't be animated, but will respond to changes in other properties and values.
- Creates many more creative possibilities for interaction of pixels
Browser support
30+
35+
7.1+ / iOS 8
