我怎样才能做我的第一个<LI>标签在排序中动态变化时着色

Question

Sorry if my title is really difficult to understand.

I am trying to make my Listview to be drag and drop, but I want my first <li> tag to be colored always after it has been dragged and droped, how can I implement that?

here is my existing code:

    $("li").first().css( "background-color", "#101F30" );
    $("li").first().css( "color", "#fff" );

// For default timezone listview
    $(function() {
        $("#allTimezoneFacets, #userTimezoneFacets").sortable({
                connectWith: "ul",
                placeholder: "placeholder",
                delay: 150
            })
            .disableSelection()
            .click(function(e) {
                var item = e.target;
                console.log(item);
            });
    });

HTML:

<div class="wrapper_timezone">
                    <ul id="allTimezoneFacets" class="facet-list">
                     <li class="facet">
                         <p class="timezone_right" id="timezone_tn_date"></p>

Any help would be really appreciated, sorry if my english is poor.

You can just use :first-child CSS selector to style the first li item

.facet-list li:first-child{
   background-color: "#101F30;
   color: "#fff";
}
