CSS媒体查询未调用min-width / max-width

时间:2013-11-14 20:39:09

标签: html css media-queries

我已经尝试解决这个问题几个小时了,而且我把头发拉了出来,不管我做了什么,它都拒绝在媒​​体标签中调用CSS,即我添加最大宽度或最小宽度。为了测试,我使媒体标签使身体变红并将最小宽度减小到可笑的低。什么都没发生。如果我离开屏幕标签而没有其他内容,则称之为

CSS:

@import url("reset.css");
@charset "iso-8859-1";
@font-face {
    font-family: cooper;
    src: url('../resources/CooperBlackStd.otf');
}

@media screen and (min-width:500){
    body{background-color:#FF0000;}
}

body {
    line-height: 28px;
}

请原谅代码的绝对混乱,但在我对此问题失去理智之前,我没有时间清理它。

2 个答案:

答案 0 :(得分:1)

您尚未指定像素值。尝试:

@media screen and (min-width:500px){
{body{background-color:#FF0000;}
}

答案 1 :(得分:1)

要扩展上一个答案,您没有指定任何单位,它不需要是像素。

您可以使用绝对长度'cm','mm','in','pt','pc'或'px',字体相对长度'em','ex','ch'或'rem'或视口百分比长度:'vw','vh','vmin'或'vmax'。这只是长度,你可以在媒体查询中使用许多其他单位,包括像素密度,设备方向,设备类型等。
