}

<p>我们可以使用 box-shadow 属性来为按钮添加阴影:</p>

<button class="button button1">阴影按钮</button>

<button class="button button2">鼠标悬停后出现阴影</button>

</body>

禁用按钮

我们可以使用 opacity 属性为按钮添加透明度 (看起来类似 "disabled" 属性效果)。

提示: 我么可以添加 cursor 属性并设置为 "not-allowed" 来设置一个禁用的图片:

CSS 实例

.disabled {
opacity: 0.6;
cursor: not-allowed;
}

按钮宽度

默认情况下，按钮的大小有按钮上的文本内容决定( 根据文本内容匹配长度 )。我们可以使用 width 属性来设置按钮的宽度:

提示: 如果要设置固定宽度可以使用像素 (px) 为单位，如果要设置响应式的按钮可以设置为百分比。

CSS 实例

.button1 {width: 250px;}
.button2 {width: 50%;}
.button3 {width: 100%;}

按钮组

移除外边距并添加 float:left 来设置按钮组:

<!DOCTYPE html>

<html>

<head>

<style>

.button {

background-color: #4CAF50; /* Green */

border: none;

color: white;

padding: 15px 32px;

text-align: center;

text-decoration: none;

display: inline-block;

font-size: 16px;

cursor: pointer;

float: left;

}

.button:hover {

background-color: #3e8e41;

}

</style>

</head>

<body>

<h2>按钮组</h2>

<p>移除外边距并添加 float:left 来设置按钮组:</p>

<button class="button">Button</button>

<p style="clear:both"><br>记住要清除浮动，否则下一个 p 元素的按钮也会显示在同一行。</p>

</body>

</html>

带边框按钮组

我们可以使用 border 属性来设置带边框的按钮组:

CSS 实例

.button {
float: left;
border: 1px solid green
}

按钮动画

鼠标移动到按钮上后添加箭头标记:

<!DOCTYPE html>

<html>

display: inline-block;

border-radius: 4px;

background-color: #f4511e;

border: none;
