當在 一個頁面顯示一個文章的內容時，如果文章太長，會造成頁面無限高，樣式很不好看，對此我有兩種解決方法：
一，將內容放在<div>標簽中，然后設置標簽的style，具體<div style="overflow:auto;height:50px;">，這里的height是設置div的高度，然后設置當高度超過后會顯示一個滾動條，不會破壞頁面的整體效果
二，在后來通過分割字符來進行分頁，代碼如下：
前臺代碼
<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">首頁</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>
