博客园（自定义导航栏）
上一篇：博客园美化大全
在上一篇博客中已经介绍了 自动生成目录、返回顶部、爱心特效、添加github图标、扩大和缩小、设置签名、添加分享和推荐反对功能，这一篇介绍怎么自定义导航栏。
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。
<p style="text-align: center;font-size:35px;margin-bottom:19px;margin-top:20px;opacity: 0.5">Zhang_derek</p> <div id="test33" > <ul style="margin-left:0px;margin-right: 0px;" class="test11" > <div

（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; }
