当在 一个页面显示一个文章的内容时，如果文章太长，会造成页面无限高，样式很不好看，对此我有两种解决方法：

一，将内容放 在<div>标签中，然后设置标签的style，具体<div style="overflow:auto;height:50px;">，这里的height是设置div的高度，然后设置当高度超过后会显示一 个滚动条，不会破坏页面的整体效果

二，在后来通过分割字符来进行分页，代码如下：

前台代码

<div class="rBox artBox" style="margin-top:0;background-color:#f0f9ff;">

  <div class="tit02" style="background-image:url('images/tit_bg2.gif');">

      <b><a href="Default.aspx">首页</a>&gt;&gt;</b>

      <asp:Literal ID="litSubject" runat="server"></asp:Literal>&gt;&gt;

            <asp:Literal ID="litName" runat="server"></asp:Literal>

  </div>

  <h2><asp:Literal ID="litNewsName" runat="server" Text=""></asp:Literal></h2>

  <div style="font-size:14px;line-height:1.7em;padding:7px 10px 0 10px;"><asp:Literal ID="litContents" runat="server" Text=""></asp:Literal></div>

<hr style="width:98%; text-align:center;" />

  <div style="text-align:right; padding-right:20px; font-size:14px;"><asp:Literal ID="litPageNum" runat="server"></asp:Literal></div>

     <div class="clear"></div>

</div>
