博客园美化手记——CSS javascript html

写在前面：有时候可能改了一些代码以后并没有及时更新到此处，因此如果你发现我的实际博客园效果与代码有出入，你可以先试着在源代码里找找看，或者直接私信我获取最新代码。

 

论如何改变自己的博客园，变得好不好看我就不敢保证了。。。

 

我假设你是一个完全不懂网页相关的code小白。

①拥有自己的CSS代码

　　我自己是完全禁用掉了模板CSS（后期自己看情况禁不禁吧）。

　　然后会发现，blog干净得很，一点样式都没有。

　　对于我们这种小白来说，从头到尾自己写一份完整的CSS代码是不现实的，这时候我们需要一份代码模板，拿模板来改就比较容易了。

　　网上会有一些人把自己的CSS代码公开出来，当然实际上你浏览别人的blog的时候，（对于Chrome浏览器）轻按F12，你可以在style那个小栏里找到该网页的CSS代码链接（其他浏览器我就不知道了），然后就可以拿来试试水了。

　　窝的CSS代码：

 

#site_nav_under {
    display: none;
}
.c_ad_block, .ad_text_commentbox {
    display: none;
    margin: 0;
    padding: 0;
}
#ad_under_google {
    height: 0;
    overflow: hidden;
}
#ad_under_google a {
    display: none;
}

　　当初我也是拿别人代码当模板来改的，不过现在可能有点面目全非了。

　　那么现在，我们可以把这份别人的模板改成自己的风格，基本上CSS代码里参数的命名都是按元素的英文命名的，挺好认的，或者你可以把这个参数改改，看看哪里发生了变化就知道这个参数在说啥了。当你想定向寻找一个元素在CSS中各项参数的位置时，你可以寻找一下这个元素在html代码里面的位置（在Chrome浏览器中可以借助Ctrl+Shift+C来寻找元素），看一下这个元素的id和class的名字是啥，在CSS代码里找找就行了。

　　界面的颜色除了有black、white这类设定好的颜色之外，你可以找一个RGB颜色对照表，想要啥就丢啥。

　　遇到有啥不会调的参数，基本搜一下“CSS+参数名字”就有详细介绍，毕竟这东西网上教程很多。

　　比方说延迟变换可以用transition-property来做，而文字阴影效果是text-shadow，这些都是我自己在做的时候折腾了好一会的。

　　Chrome（我不知道其他浏览器能不能）有个好处是你修改了个参数，他会立刻应用变换，这样就可以调到舒心再贴进自定义CSS代码里。

　　还有就是你最好把CSS代码备份一下，不然要是误删了就GG，博主亲身体验T_T。

　　这期间你可能需要一些好看的图片什么的，我自己资源是P站找的（Pixiv），一些比较普通的就百度图片吧，然后开个画图，开个Photoshop自己改改就能用了，图床直接用博客园就行了（开个不发布的随笔就能存图了，图片上右键可以获得图片链接地址）。

　　这时候自己的blog已经比较好看了是不是啊？

②修改鼠标图案

　　把这个放在第二是我按自己的操作顺序来的。

　　没啥特别要说的，就是如果你需要存储的是cur之类的放不进图床的文件可以找个直链网站，这里推荐小白的文件床（http://fq.wc.lt/），不知道是哪位大神弄的，太良心了。

　　upd：小白文件床貌似不支持cur文件了，只能另找了

body{cursor:url('http://fq.wc.lt//up/1499563659.cur'),auto;}
A{cursor:url('http://fq.wc.lt//up/1499563659.cur'),auto;}

③JS什么的

　　折腾了一段时间以后应该对html也有了一定的了解，首先在博客园管理的设置页中把JS代码权限申请了，批准挺快的，然后就可以为所欲为了（雾）……

　　首先你可以在侧边栏加点计数器，加点flash动画什么的，这些一般是找别人做好的，链过来或者抄过来就行。

　　要搞js的话建议在网上找个教程看看，看它个把小时就基本能拿来用用了（其实跟c++挺像的，应该说java跟c++比较像吧），以后遇到不会的回去查查就行。

　　我拿js做的大概就是加了一些小挂件，比方说左上角的西瓜是获取main元素之后把opacity（透明度）调到0就行，结合一下onmouseover、onmouseout什么的就能做出浮动效果，还是很赞的。

　　尝试着做个推荐按钮，一直做不成，估计是被过滤了。发邮件去问博客园那边也是这是禁止的。

　　目录我是改自sakuraph的，感谢dalao。

以后还有什么再补吧。

④用Canvas和requestAnimFrame做动画特效

　　指的是背景里面跑来跑去的星星什么的……

　　这东西也不难学的，就是requestAnimFrame会自动帮你定时调用一段函数，然后你在函数里面用canvas写写绘图就行了，写得再丑最后效果好像都是挺平滑的，好像是浏览器会自动优化。

　　我大概就是让每一帧画面都有一定概率生成一个星星（图什么的自己拿PS画画就行了），然后给一个下落速度和角度什么的。本来用了一些弹性碰撞公式来做碰撞的，但最后效果并不好，索性忽略质量差别的问题，碰撞了就交换速度和角度。

　　至于侧边栏那个就也是这样简单地写一个物理模型而已。

　　学习使用requestAnimFrame的时候感觉最大的难点就是网上的代码大多加了很多效果，而导致代码很长，研读起来找不到自己真正想要的部分，其实只需要像下面这么写。　　

<script>
    window.requestAnimFrame=
        window.requestAnimationFrame||
        window.webkitRequestAnimationFrame||
        window.mozRequestAnimationFrame||
        window.oRequestAnimationFrame||
        window.msRequestAnimationFrame||
        function(callback){window.setTimeout(callback, 1000/60);};
    function work(timestamp){
        timer=requestAnimationFrame(work);
    }
    timer=requestAnimationFrame(work);
</script>
View Code

　　这时work函数你就想干啥干啥了，超舒服的。感觉学了这么多年OI终于在此时派上用场。

　　下面是加了新特效后，我的页首HTML代码：

⑥修改博客园图标

 　　忽然想到还有这种东西可以修改。

　　正常在html里面加这句就可以了

<link rel="shortcut icon" href="图标地址" type="image/x-icon" />

　　但不知道是什么原因，好像没生效。

　　那就加个js来改好了。

<script type="text/javascript">
　　var x = document.createElement('link');
　　x.rel = "shortcut icon";
　　x.href = "图标地址";
　　document.getElementsByTagName("head")[0].appendChild(x);
</script>

⑦图片水纹效果

　　这个效果学(chao)习自悠悠 ：http://uusama.com/643.html

　　最近考试蛮多的（这个借口不错）没什么时间捣鼓所以直接copy了dalao的主体代码。图片跨域的问题我是从自己服务器请求一个base64码过来。（也许会有点烧流量？

　　代码可以移步dalao的github

　　效果在侧边栏上方头像处

　　PS:如果你copy了我的代码，base64的请求可能只能用于博客园，因为服务器的跨域只放了博客园。

 

⑧ javascript自制函数图像绘制器

　　（现在的软件那么成熟，你捣鼓这玩意有什么意义？= =

　　写出来了顺便移植到blog侧边栏惹……

　　详见这篇文章javascript自制函数图像生成器

　　移植后代码：
