测试CSS"混合混合模式"

我想使用CSS的属性:

mix-blend-mode: soft-light;

And I will test by Modernizr for fallback bla bla...

Tested :

Modernizr.mixblendmode //undefined
Modernizr.testProp('mixblendmode'); //false
Modernizr.addTest('mixblendmode'); // no-mixblendmode

What am I missing ?

Tested on Firefox, CSS its work, but how to test with Modernizr ?

得到它了 :

Modernizr.addTest('mix-blend-mode', function(){
    return Modernizr.testProp('mixBlendMode');
});

(或没有Modernizr)

if('CSS' in window && 'supports' in window.CSS) {

    var support = window.CSS.supports('mix-blend-mode','multiply');

    /* Add class like Modernizr */
    /* -- jQuery -- */
    $('html').addClass(support?'mix-blend-mode':'no-mix-blend-mode'); // jQuery
    /* -- Pure JS -- */
    document.getElementsByTagName('html')[0].className += support ? ' mix-blend-mode' : ' no-mix-blend-mode';
    /* -- Pure JS (IE9+) -- */
    document.querySelector('html').classList.add(support ? 'mix-blend-mode' : 'no-mix-blend-mode');
}

(或CSS)

@supports(mix-blend-mode:multiply) {

}
