鼠标悬停按钮
我们可以使用 :hover 选择器来修改鼠标悬停在按钮上的样式。
提示: 我们可以使用 transition-duration 属性来设置 "hover" 效果的速度:
<!DOCTYPE html>
<html>

<meta charset="utf-8">
<style>
.button {
background-color: #4CAF50;
/* Green */

margin: 4px 2px;
-webkit-transition-duration: 0.4s;
/* Safari */
transition-duration: 0.4s;
cursor: pointer;
}
.button1 {
background-color: white;
color: black;
border: 2px solid #4CAF50;
}
.button1:hover {
background-color: #4CAF50;
color: white;
}
.button2 {
background-color: white;
color: black;
border: 2px solid #008CBA;

}
.button5:hover {
background-color: #555555;
color: white;
}
</style>
</head>
<body>
<h2>鼠标悬停按钮</h2>
<p>我们可以使用 :hover 选择器来修改鼠标悬停在按钮上的样式。</p>
<p><strong>提示:</strong> 我们可以使用 <code>transition-duration</code> 属性来设置 "hover" 效果的速度:</p>
<button class="button button1">Green</button>
<button class="button button2">Blue</button>
<button class="button button3">Red</button>
<button class="button button4">Gray</button>
<button class="button button5">Black</button>
</body>
</html>
按钮阴影
我们可以使用 box-shadow 属性来为按钮添加阴影:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<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;
margin: 4px 2px;
cursor: pointer;
-webkit-transition-duration: 0.4s;
/* Safari */
transition-duration: 0.4s;
}
.button1 {
box-shadow: 0 8px 16px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
}
.button2:hover {
box-shadow: 0 12px 16px 0 rgba(0, 0, 0, 0.24), 0 17px 50px 0 rgba(0, 0, 0, 0.19);
}
</style>
</head>
<body>
<h2>按钮阴影</h2>
<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>
</html>
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:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<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;
margin: 4px 2px;
cursor: pointer;
}
.disabled {
opacity: 0.6;
cursor: not-allowed;
}
</style>
</head>
<body>
<h2>禁用按钮</h2>
<p>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)。</p>
<button class="button">正常按钮</button>
<button class="button disabled">禁用按钮</button>
</body>
</html>
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。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<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;
margin: 4px 2px;
cursor: pointer;
}
.button1 {
width: 250px;
}
.button2 {
width: 50%;
}
.button3 {
padding-left: 0;
padding-right: 0;
width: 100%;
}
</style>
</head>
<body>
<h2>按钮宽度</h2>
<p>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:</p>
<p><strong>提示:</strong> 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。</p>
<button class="button button1">250px</button><br>
<button class="button button2">50%</button><br>
<button class="button button3">100%</button>
</body>
</html>
按钮组
移除外边距并添加 float:left 来设置按钮组:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<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>
<button class="button">Button</button>
<button class="button">Button</button>
<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:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
.button {
background-color: #4CAF50;
/* Green */
border: 1px solid green;

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>带边框按钮组</h2>
<p>Add borders to create a bordered button group:</p>
<button class="button">Button</button>
<button class="button">Button</button>
<button class="button">Button</button>
<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>

鼠标移动到按钮上后添加箭头标记:
<!DOCTYPE html>
