Why doesn't input::-webkit-slider-thumb, input::-moz-slider-thumb work?

Question

Sass

Hello, having created a small slider to support the ego, not only in webkit browsers, you have to use the scss type template

%thumb {
/*something*/
}
input::-webkit-slider-thumb {
          @extend %thumb;
}
input::-moz-slider-thumb {
          @extend %thumb;
}

But why the type variant

input::-webkit-slider-thumb, input::-moz-slider-thumb {
          @extend %thumb;
}

does not work

Answer 1

Perhaps you have something else wrong, so it's all working ok. Do View Compiled CSS and see that everything compiles fine.
