附上我的css,怎么把这个修改成单独某个下拉框的样式,显示结果如下图,放在初始化后就把所有的下拉框都给修改了setTimeout(function(){$(".report-main-parameter-container-controller-combo .bi-border").css({"border-color":"#0091ff","border-radius":"6px","background-color":"#dae9ff"})$(".report-main-parameter-container-controller-combo .bi-icon-button").css("color", "#0091ff");},300)
