span#big { vertical-align:middle; display:inline-block; margin-left:6px; margin-right:20px; width:183px; height:14px; border:2px solid #a4a4a4; border-radius:14px; behavior: url(PIE.htc);}

span#min { display:block; height:100%; width:70%; background:#fe0002; border-top-left-radius:14px; border-bottom-left-radius:14px; behavior: url(PIE.htc);

原理：大盒子里套個小盒子，

大盒子給固定寬

小盒子的寬用%表示，（利用寬度的繼承性，比如50%，就只有大盒一半寬）

這個css 里的50% 將來是要用來用js動態(tài)化的，一但動態(tài)起來，就達成了進度條的效果了

如何使用CSS3制作一個簡單的進度條

如果不考慮IE的話，用css3應該不難：1、邊框用背景圖或純色都可以，配合圓角和陰影；2、里面的進度條可以用垂直方向的線性漸變及陰影配合實現(xiàn)；3、最后配合js動態(tài)修改里面進度條div的寬度和文字的顯示即可。

分享幾種極具創(chuàng)意的HTML5/CSS3進度條特效

section class="container"

div class="progress"

span style="width: 20%;"span20%/span/span

/div

div class="progress"

span class="green" style="width: 40%;"span40%/span/span

/div

div class="progress"

span class="orange" style="width: 60%;"span60%/span/span

/div

div class="progress"

span class="red" style="width: 80%;"span80%/span/span

/div

div class="progress"

span class="blue" style="width: 100%;"span100%/span/span

/div

/section

從HTML結(jié)構(gòu)中我們可以看出，類名為progress的div是整個進度條的父容器，里面的span則是當前進度，通過width來定義不同的進度值，同時定義不同的顏色類，比如orange，以便待會在CSS中進行樣式渲染。
