媒体查询无法在Chrome中运行但在Firefox中运行？

Question

我目前正在处理的网站没有为我的样式设置为低于480px的Chrome设备,但是在firefox中运行,chrome正在接收800px和1200px的媒体查询,我不能为我的生活弄明白为什么它没有拿起480px媒体查询.

请参阅下面的样式表.

@media screen and (max-width:1200px) { 

.ui-tabs .tab {
    clear:both; 
    height:386px;

你有一些不好的嵌套,或不正确的括号.如果我删除实际样式,它看起来像这样:

@media screen and (max-width:1200px) { 

}

@media screen and (max-width:800px) {

/* Missing } brace here */

@media screen and (max-width: 480px) {

}

Firefox可能只是以不同方式处理错误.照顾好你,你应该好好去.
