Css 使用模块的样式覆盖门户的样式-div标记之间的空格

我有一些标签与文本框和下拉列表水平对齐。下拉列表和文本框之间出现间隙。如果我检查元素，它会向我显示门户的css文件，其中不包括导致我希望减少的间隙/垂直空间的信息。我想要的是覆盖模块级别上的这些设置

在屏幕截图上，我用firefox上的“web开发者”工具突出显示了这种风格。此时会出现下拉列表之间的间隙

 <div class="ColOne">
        <asp:Label ID="lblCategory" runat="server" Text="Category" CssClass="labelStyle" style="position: relative"></asp:Label>
    </div>
    <div  >
        <asp:DropDownList ID="ddlCategory" runat="server"  DataSourceID="sqlCategories" DataTextField="Name" DataValueField="CategoryID" AutoPostBack="True"></asp:DropDownList>
    </div>
    <div class="ColOne">
        <asp:Label ID="lblSubCategory" runat="server" Text="Sub Category" CssClass="labelStyle"></asp:Label>
    </div>
   <div >
        <asp:DropDownList ID="ddlSubCategory" runat="server" DataSourceID="sqlSubCategory" DataTextField="Name" DataValueField="SubCategoryID"></asp:DropDownList>
    </div>

单击显示样式信息，我将获得以下信息：

我通过添加以下内容来修复它

div.ColEmpty input[type="text"], select, textarea {
    margin-top:0;
    position: relative;
  line-height:0px;
    top: 2px;
     margin-bottom: 0px;
}

<div class="ColEmpty">
        <asp:DropDownList ID="ddlSubCategory" runat="server" DataSourceID="sqlSubCategory" DataTextField="Name" DataValueField="SubCategoryID"></asp:DropDownList>
</div>

你有没有试过去掉上面的填充物：12px；来自科隆分区？否则，您提供的代码中没有任何原因this@SW4我现在已经测试过了，但它不会影响差距。我使用填充顶部：12px在中间移动标签的文本。我想我们需要更多的代码，或者一个生动的例子。debug@SW4我不能提供一个自动取款机的实例。请让我知道您希望看到代码的哪一部分。我刚刚添加了从default.css获得的代码

div.ColEmpty input[type="text"], select, textarea {
    margin-top:0;
    position: relative;
  line-height:0px;
    top: 2px;
     margin-bottom: 0px;
}

<div class="ColEmpty">
        <asp:DropDownList ID="ddlSubCategory" runat="server" DataSourceID="sqlSubCategory" DataTextField="Name" DataValueField="SubCategoryID"></asp:DropDownList>
</div>
