今天给大家分享一款基于css3的简单的鼠标悬停按钮。这款悬停按钮鼠标经过前边框是间断的。当鼠标经过的时候边框间隔消失。效果图如下：
实现的代码。
html代码：
<div class="container">
<p>
Single gradient border</p>
<a href="#" class="btn">Click Me!</a> <a href="#" class="btn">Very long link text here</a>
</div>
<div class="container">
<p>
Pseudo elements at a fixed size. Nasty 1px drop on hover</p>
<a href="#" class="btn2">Click Me!</a> <a href="#" class="btn2">Very long link text
here</a>
</div>
<div class="container">
<p>
Multiple borders using pseudo elements with gradient borders</p>
<a href="#" class="btn3">Click Me!</a> <a href="#" class="btn3">Very long link text
here</a>
</div>
<h1>
<a href="#" class="btn3">A Huge Link</a></h1>
