自定义导航栏。
效果如下：
1.1.自定义导航栏
我的博客皮肤用的是anothereon001,假如你的博客用的是其它皮肤，样式需要自己修改，要想达到一样的效果，建议也用同款皮肤
（1）把默认的导航栏给隐藏掉
既然我们想要自定义导航栏，默认的导航栏就不能显示
#header{display:none;}
（2）页首html代码
里面一个ul包含很多div（一个div代表一个分类），div里面是下拉框（a标签，里面是你的博客文章地址），自己可以随意增加删除分类。

（3）页面定制css
#test33 ul {
margin: 0;
padding: 0;
list-style-type: none; /*去除li前的标注*/
background-color: #333;
overflow: hidden; /*隐藏溢出的部分，保持一行*/
}
#test33 li {
float: left; /*左浮动*/
}
#test33 li a, .dropbtn {
display: inline-block; /*设置成块*/
color: white;
text-align: center;
text-decoration: none;
padding: 14px 16px;
}
#test33 li a:hover, .dropdown:hover .dropbtn { /*鼠标移上去，改变背景颜色*/
background-color: blue;
}
#test33 .dropdown {
/*display:inline-block将对象呈递为内联对象，但是对象的内容作为块对象呈递。旁边的内联对象会被呈递在同一行内，允许空格。*/
display: inline-block;
}
#test33 .dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
#test33 .dropdown-content a {
display: block;
color: black;
padding: 8px 10px;
text-decoration:none;
}
#test33 .dropdown-content a:hover {
background-color: #a1a1a1;
}
#test33 .dropdown:hover .dropdown-content{
display: block;
}
1.2.设置背景图片
给自己的博客设置一个好看的背景图片
（1）首先在设置---->>>相册里面添加一张背景图片
（2）页面定制css代码
background-image里面的地址就是你相册里面添加的图片地址
body {
background-color: #efefef;
background-image:url(http://images.cnblogs.com/cnblogs_com/today-happy/1214264/t_blog.jpg);
background-repeat: no-repeat;
background-attachment: fixed;
background-position: center 0;
background-size: cover;
padding-top:0px;
}
1.3.一个好看的时钟
上一篇介绍了添加时钟，但是又发现了一个更好看的时钟，就分享给大家了，效果如下：
（1）公告栏里面
时钟的宽高按可以自己设置合适的大小
<div id="clockdiv"> <canvas id="dom" width="120" height="120">时钟canvas</canvas> </div> <script type="text/javascript" src="https://files.cnblogs.com/files/siwuxie095/clock.js"></script>
（2）页面定制css代码
/*公告栏时钟*/
#clockdiv {
text-align: left;
}
