Slider CSS :focus Selector

Webix JS
1

Hi,
I would like to signal the focus state of a slider, I did this:

onFocus: function () { 
    webix.html.addCss(this.$view.firstChild.firstChild,'webix_slider_focus');
},
onBlur: function () { 
    webix.html.removeCss(this.$view.firstChild.firstChild,'webix_slider_focus');
},

.webix_slider_focus {
background-color: #ccc !important;
border: 1px solid #ccc !important;
}

which is the right solution?

Thank you

Never mind, I did it with wrapping Slider’s JQuery in protoUI:
