<body>
<form id="form1" runat="server">
<div class="main">
<div class="title1"><span><asp:Label ID="Label1" runat="server" Text="Label"></asp:Label></span></div>
<div style="text-align:center"><a href="javascript:ts('body',1)">+ 放大字体</a> | <a href="javascript:ts('body',-1)">+ 减小字体</a></div>
<div class="titlecont"><p style="padding-left:30px"><asp:Label ID="Label2" runat="server" Text="Label"></asp:Label></p></div>
</div>
</form>
</body>
</html>
以上是在网上找的一个放大或缩小字体的JS, 我用了，上面那个是针对整个页面的放大或缩小，
请教怎么样可以只放大或缩小内容层即：div class="titlecont">里的字体呢？我不想让整页都放大缩小。请指教！谢谢！
