标题: 求助CSS高手，代码修改
CSS代码，仿Chrome标签页(梯形标签页)，用于文件管理软件Tablacus Explorer。显示效果：

想做些改进，主要是区分各个“非当前页”、完善梯形形状、自定义各种背景颜色，如图：



最终理想样式：



CSS代码（待修改）
  1. .tab, .tab2, .tab3,
  2. .tab:hover, .tab2:hover, .tab3:hover {
  3.   box-shadow: none;
  4. }

  6. .tab0 {
  7.   padding: 3px 0 0 12px;
  8.   background-color: ActiveCaption;
  9. }

  11. .tab, .tab2, .tab3 {
  12.   position: relative;

  16.   opacity: 1;
  17. }

CSS代码源网页，有“仿Chrome标签页”和“仿FireFox标签页”两种代码，还有执行结果截图。
