试图找出为什么ie一直忽略我的CSS。我的选择器只有3494，我的文件大小是960KB，并且在被忽略之前有15600行，但缩小到更少的行没有效果。
在ie10，firefox，chrome中工作正常。
所有这些都说，我读过的一切都是只有选择器限制，导入嵌套限制和样式表限制。
有什么想法吗？
它正在扼杀箭头风格。通过移动一些东西，我能够让它停在不同的地方，所以我怀疑它是语法。
这里是跳过最后的东西，

答案 0 :(得分：3)
可能的解决方案：
修复所有语法错误：
.ui-icon-arrow-4-diag{background-position:-16px -80px}
需要有一个半列
.ui-icon-arrow-4-diag{background-position:-16px -80px;}
这些错误可能会导致问题。
