<script>
function color1(event)
{
var cubebody=document.getElementById('body_color');
cubebody.className = 'graydient1';
}
function color2()
{
var cubebody=document.getElementById('body_color');
cubebody.className = 'graydient2';
}
function color3()
{
var cubebody=document.getElementById('body_color');
cubebody.className = 'graydient3';
}
function color4()
{
var cubebody=document.getElementById('body_color');
cubebody.className = 'graydient4';
}
</script>
<style>
/* 下拉按钮样式 */
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
} /* 容器 <div> - 需要定位下拉内容 */
.dropdown {
position: fixed;
left: 50px;
top: 20px;
display: inline-block;
} /* 下拉内容 (默认隐藏) */
.dropdown-content {
display: none;
position: absolute;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
} /* 下拉菜单的button */
.dropdown-content button {
background-color: #4CAF50;
border-radius: 6px;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
} /* 鼠标移上去后修改下拉菜单链接颜色 */
.dropdown-content a:hover {background-color: #f1f1f1} /* 在鼠标移上去后显示下拉菜单 */
.dropdown:hover .dropdown-content {
display: block;
} /* 当下拉内容显示后修改下拉按钮的背景颜色 */
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}
</style> <div class="dropdown">
<button class="dropbtn">Background</button>
