css - 改变 ionic 范围 slider handle 的颜色

Question

如果我尝试将 ionic 范围 slider (可在此处获取:https://github.com/IonDen/ion.rangeSlider)的默认颜色从红色(默认)更改为蓝色，如下所示:

.irs-slider.single {
    background: blue;
}

变成正方形:

(最初它看起来像一条细红线:)

我做错了什么？

        type: "single",
        min: 0,
        max: 1000,
        from: 200,
        to: 500,
        grid: true
    });

.irs-slider.single {
    background: blue;
}
