鼠标经过显示按钮的详细信息

之前介绍了几款css3实现的按钮，今天为网友来款比较新鲜的，用css3的data-attribute属性开发按钮，当鼠标经过显示按钮的详细信息。而且实现过程很简单，几行代码就搞定。大家试一试吧。如下图：

不错吧，贴上实现代码：

html代码：

<button data-hover="爱编程（w2bc.com）收集编程资料，web前端案例"> 爱编程</button>

 

<button data-hover="爱编程（w2bc.com）收集编程资料，web前端案例">
            爱编程
</button>

 

 

css代码：

button { background: #db701f; border: solid 7px #000; padding: 20px; box-shadow: inset 0 0 6px #824212; text-transform: uppercase; font-weight: bold; font-family: "Tahoma" , sans-serif; text-shadow: 1px 1px 3px #824212; color: #fff; position: relative; 300px; font-size:16px; } button:hover { background: green; } button:hover:before { /* ------- THIS IS THE MAGIC ----------------*/ content: attr(data-hover); /* ------------------------------------------*/ display: block; background: #000; position: absolute; top: 100%; left: -7px; right: -7px; padding: 15px; } button:hover:after { content: ""; position: absolute; display: block; 0; height: 0; border: solid 10px transparent; border-bottom-color: #000; bottom: 0; left: 50%; margin-left: -10px; z-index: 2; } .note { margin-top: 100px; display: block; }
