用icomoon下载的图标和现有图标冲突了吗？

enonieerht

我按照http://doc.wex5.com/custom-icon/的方法，把下载的文件中的style.css改名为icomoon.icons.css，并在设计器里引用这个css。在指定图标时发现下拉框里是多了icomoon这个目录，但是图标是空的，不显示。然后icon目录下的所有图标都变成空白了。控制台有很多红色的错误信息：

需要注意的是！整个项目所有资源都需要放在UI2项目中！不能只放一两个文件！肯定是不起作用的！

解决了。修改了字体目录下css的内容，保证类名和css的文件名一样，同时不能使用已有的类名，就可以了，因为X5自带一个叫icon的类，而我下载的icomoon的默认css文件里也有这个icon类，后来改成icomoon类，同时把css文件名style.css改成icomoon.icons.css就可以了。css内容如下：
但是好像eclipse要重启才能在设计器里看到更新后的图标，不过在浏览器里马上可以看到。
@font-face {
  font-family: 'icomoon';
  src:  url('fonts/icomoon.eot?4a54yu');
  src:  url('fonts/icomoon.eot?4a54yu#iefix') format('embedded-opentype'),
    url('fonts/icomoon.ttf?4a54yu') format('truetype'),
    url('fonts/icomoon.woff?4a54yu') format('woff'),
    url('fonts/icomoon.svg?4a54yu#icomoon') format('svg');
  font-weight: normal;
  font-style: normal;
}

.icomoon .icomoon-shoeprints {
  /* use !important to prevent issues with browser extensions that change fonts */
  font-family: 'icomoon' !important;
  speak: none;
  font-style: normal;
  font-weight: normal;
  font-variant: normal;
  text-transform: none;
  line-height: 1;

  /* Better Font Rendering =========== */
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.icon-shoeprints:before {
  content: "\e900";
}

原先下载的css是这样子的：
@font-face {
  font-family: 'icomoon';
  src:  url('fonts/icomoon.eot?4a54yu');
  src:  url('fonts/icomoon.eot?4a54yu#iefix') format('embedded-opentype'),
    url('fonts/icomoon.ttf?4a54yu') format('truetype'),
    url('fonts/icomoon.woff?4a54yu') format('woff'),
    url('fonts/icomoon.svg?4a54yu#icomoon') format('svg');
  font-weight: normal;
  font-style: normal;
}

[class^="icon-"], [class*=" icon-"] {
  /* use !important to prevent issues with browser extensions that change fonts */
  font-family: 'icomoon' !important;
  speak: none;
  font-style: normal;
  font-weight: normal;
  font-variant: normal;
  text-transform: none;
  line-height: 1;

  /* Better Font Rendering =========== */
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.icon-shoeprints:before {
  content: "\e900";
}
