MVC应用程序页面加载没有样式以后第二种样式适用

Question

创建了一个MVC应用程序。这里我只有一个视图页面。页面加载时，控件css不应用，2-3秒后css将被应用。 它看起来很奇怪。尝试但没有得到任何线索来找到问题。

使用的Bootstrap表类

@section Styles
{
<link href="~/Content/themes/base/jquery-ui.css" rel="stylesheet"    type="text/css" />
<link href="~/Content/Common.css" rel="stylesheet" type="text/css" />
<link href="~/Content/bootstrap.css" rel="stylesheet" type="text/css" />
<link href="~/Content/bootstrap-select.min.css" rel="stylesheet" type="text/css" />
<link href="~/Content/DayOfWeek.css" rel="stylesheet" type="text/css" />
}

@section scripts
{
<script src="~/Scripts/jquery-3.1.1.js"></script>
<script src="~/Scripts/jquery-ui-1.12.1.min.js"></script>
<script src="~/Scripts/bootstrap-select.min.js"></script>
<script src="~/Scripts/Index/Index.js" type="text/javascript"></script>
<script src="~/Scripts/Index/MonthYear.js" type="text/javascript"></script>
<script src="~/Scripts/Index/MutualExclusiveParam.js"  type="text/javascript"></script>
<script src="~/Scripts/Index/YearMonthDay.js" type="text/javascript">  </script>
<script src="~/Scripts/Index/HourMinute.js"></script>
<script src="~/Scripts/Index/multiselect.js" type="text/javascript"></script>
<script src="~/Scripts/Index/DayOfWeek.js" type="text/javascript"></script>

<script type="text/javascript">
    $('.db').attr('data-live-search', true);
</script>
}
<div class="col-md-1">
        @Html.Label(@parameter.parameterLabel)
    </div>
        <div class="col-md-2">
            @Html.DropDownList(parameter.parameterLabel.Trim() + '_' + parameter.parameterId, Model.salesAreaItems)
        </div>

请告诉我，对此有任何想法。
