我有这个用UIkit设计的单页网页。 现在我想在WebForm中使用它，并在代码隐藏文件中使用C＃Code处理按钮事件。
第一个问题是，只要我将网页添加到表单，第一个表单的布局就会发生变化。这是为什么？
其次，按钮总是提供页面刷新。我怎么能避免这种情况？
这是我的网页代码：
<div class="uk-block uk-block-secondary uk-width-1-1">
<div class="uk-grid uk-width-5-6 uk-container-center uk-grid-match" data-uk-grid-match="{target:'.uk-panel'}" data-uk-margin="{cls:'uk-margin-top'}">

这是从http://getuikit.com/使用的css内容：
<link rel="stylesheet" href="css/uikit.gradient.css" />
<script src="js/jquery.js"></script>
<script src="js/uikit.min.js"></script>
<!-- CSS -->
<link rel="stylesheet" href="css/components/datepicker.gradient.css" />
<link rel="stylesheet" href="css/components/tooltip.gradient.css" />
<link rel="stylesheet" href="css/components/notify.gradient.css" />
<!-- Javascript -->
<script src="js/components/datepicker.js"></script>
<script src="js/components/tooltip.js"></script>
<script src="js/components/notify.js"></script>
有人知道如何解决这个问题吗？
