web前端-css教程
进度条是网站中常见的一种，今天经过研究外国一个网站的例子，试着用css3来实现进度条：
人人分销插件源码,vscode中git命令,163 源 ubuntu,静态部署tomcat,sqlite是哪个公司的,自定义生成手机页面前端框架,广东有什么爬虫养殖户,php curl 64位,seo配置文件,时时彩票网站源代码,电商商城html网页源码,html订单列表模板lzw
html代码如下：
化工网站源码,ubuntu光盘本地源,tomcat启动和停止访问,手工爬虫机器,php 站点发布,seo公司实力乐云seolzw
Set above to:
usb 检测 源码,vscode ,ubuntu安装im,tomcat吞吐,sqlite极速存储,阿里云服务器数据迁移,h5上传附件插件,前端mvvm框架目的,java 爬虫获取图片,try php,泽成SEO,课件网站源码,qt获取网页源码,wordpress 企业网站模板,前端管理页面模板,企业表单管理系统,PHP红包程序lzw

css样式：
body{ background:#222; width:360px; margin:0 auto; font:13px rebuchet MS,Arial,Helvetica;}h2, p {text-align: center;color: #fafafa;text-shadow: 0 1px 0 #111; } a {color: #777;} .progress-bar{ background-color:#1a1a1a; height:25px; padding:5px; width:350px; margin:70px 0 20px 0;-moz-border-radius:5px; -webkit-border-raidus:5px; border-radius:5px;-moz-box-shadow:0 1px 5px #000 inset, 0 1px 0 #444;-webkit-box-shadow:0 1px 5px #1a1a1a inset,0 1px 0 #444; box-shadow:0 1px 5px inset,0 1px 0 #444; }.progress-bar span{ display:inline-block; height:100%; background-color:#777; -moz-border-radius:3px;-webkit-border-radius:3px; border-radius:3px; border-radius:3px; box-shadow:0 1px 0 rgba(255,255,255,.5) inset; -webkit-box-shadow:0 1px 0 rgba(255,255,.5) inset; -moz-box-shadow:0 1px 0 rgba(255,255,.5) inset; -webkit-transition:width .4s ease-in-out; -moz-transition:width .4s ease-in-out;-ms-transition:width .4s ease-in-out;transition: width .4s ease-in-out; }
主要实现进度条的背景：

jquey部分：
$(document).ready(function(){ $(.quarter).click(function(){ $(this).parent().prev().children("span").css(width,25%); }); $(.half).click(function(){ $(this).parent().prev().children(span).css("width",50%); }); $(.three-quarters).click(function(){$(this).parent().prev().children(span).css(width,75%);});$(.full).click(function(){ $(this).parent().prev().children(span).css(width,100%); }) })
