在IE和Firefox里面实现页面半透明

今天用firefox看网页,突然看见一个页面竟然在firefox里面也可以透明,很奇怪,就下了那个页面的CSS观看,结果发现原来是使用了:
-moz-opacity: 0.9

说起来还真郁闷,我自己弄了实验,结果忽略了前面那个"-"小杠杠,让我折腾了近一个小时都在研究那个页面,因为那个页面还有很多JS文件。刚开始我以为是图片,保存了背景图片发现不是,后来以为是JS,结果也不是。呵呵。真是扰了一个大弯,以前都是用类似FILTER: alpha(opacity=90);这样的语句来实现的,但是只能在 IE内核的浏览器有效果。

总结,要让页面在firefox和IE中都能透明,只要在CSS样式里面同时使用:

  1. FILTER: alpha(opacity=90);
  2. -moz-opacity: 0.9;

找到一个可以替代ghs.google.com的地址

用Goole Blogger的自定义域名功能需要用到 ghs.google.com 做CNAME,或者用ping ghs.google.com 得出的IP做一个A记录.但是,伟大的GFW已经把 ghs.google.com 和部分IP屏蔽在大陆之外.这样的壮举使得我们的自定义域名不能正常访问,或者让你的网页背景.图片被滤掉,精心做成的模板变得惨白不堪. 那么,我们可不可以找一个替代 ghs.google.com 的地址呢?当然能.因为Google是强大的.它有许多有用的IP地址让你去探寻. 对 ghs.google.com 分析研究后发现, ghs.google.com 这台服务器并没有提供实质性的服务,而只是选择访问者访问最快的服务器(Google全球性公司,很多地区都有服务器).我们只要找到其他服务器的IP地址,并且这个IP地址没被屏蔽,那么就成了. 寻找这样的IP地址需要用到tracert命令.即在CMD模式下输入:tracert ghs.google.com ,在已经屏蔽的当下,最后自然得不出结果,这就需要我们使用代理了.使用不同地区的代理运行tracert ghs.google.com 命令. tracert ghs.google.com 的最后一跳会有类似这样的域名: eh-in-f121.google.com 如果在不用代理的情况下,你能ping通这个域名,那么恭喜你,你找到了!现在就可以用这个域名代替 ghs.google.com 设置你的CNAME了,ping出的IP地址可以做A记录,CNAME和A记录,只做其中之一就可以. hs-in-f121.google.com 64.233.179.121 eh-in-f121.google.com 72.14.207.121 bx-in-f121.google.com 66.249.81.121 ik-in-f121.google.com 66.249.91.121 这4个在我所在地区不能使用,而可以使用 tw-in-f121.google.com 72.14.235.121 或者209.85.171.121也可用 下面是一些不断更新的:74.125.43.121 除了使用代理来寻找,也可以通过一些网站提供的功能来寻找这个地址,很方便,就是使用网站提供的Traceroute.这些网站有: h...
