本篇文章为大家展示了怎样理解CSS3中的Media Queries,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
一、Media Queries 支持的属性
二、关键字
and - 结合多个媒体查询 not - 排除某种制定的媒体类型 only - 用来定某种特定的媒体类型
三、引用样式示例

@media screen and (min-width: 980px) { //css code } @screen and (min-width:768px) and (max-width:980px) { //css code } @screen and (min-width:480) and (max-width: 768px) { //css code } @screen and (max-width:320px) { //css code } @media screen and (max-device-width: 480px) { //max-device-width等于480px } @media screen and (device-aspect-ratio: 16/9), screen and (device-aspect-ratio: 16/10) { //设备宽高比 } @media all and (orientation:portrait) { //竖屏 } @media all and (orientation:landscape) { //横屏 }
五、I8的兼容性问题解决
问题根源:
在项目的CSS文件中采用了media这东东来根据视窗的大小自动调整布局,但是,但是IE8及以下版本浏览器不支持CSS3 media queries,也就是@media screen and (max-width: 900px) 里面的css代码没有执行,

@media screen and (max-width: 900px) { ... }
这如何是好啊,网上倒是有不少人提出解决方法,最简单的方法就是:
IE8和之前的浏览器不支持CSS3 media queries,你可以在页面中添加css3-mediaqueries.js来解决这个问题。

原来如此,还挺简单嘛,结果大失所望啊,项目中怎么试怎么就不行呢,还望试过可行的同仁点拨点拨啊,没办法只能采用另一种稍微复杂些的方法,也是从网上学来,这里要考虑两个问题,一是只有IE8及其低版本才做此处理,二是只有浏览器缩小到某一个大小范围后才做此处理。方法如下:
原理:采用jquery,其实不懂,会用就行,然后在html中根据需要来改变对应的CSS文件
解决方法:
在所有页面的共用js文件后面添加如下代码:
JavaScript Code复制内容到剪贴板
/*Adjust the layout in IE8 and lower than IE8 when the browser is narrow*/ function processLowerIENavigate() { var isIE = document.all ? 1 : 0; if (isIE == 1) { if(navigator.userAgent.indexOf("MSIE7.0") > 0 || navigator.userAgent.indexOf("MSIE 8.0") > 0) { // var doc=document; var link=document.createElement("link"); link.setAttribute("rel", "stylesheet"); link.setAttribute("type", "text/css"); link.setAttribute("id", "size-stylesheet"); link.setAttribute("href", ""); var heads = document.getElementsByTagName("head"); if(heads.length) heads[0].appendChild(link); else document.documentElement.appendChild(link); [xss_clean](""); [xss_clean](""); } } } var lowerIE8 = processLowerIENavigate(); media_screen.js文件内容如下,直接从网上copy: function adjustStyle(width) { width = parseInt(width); if (width < 902) { //alert("900"); //alert(width); $("#size-stylesheet").attr("href", ""); } } $(function() { adjustStyle($(this).width()); $(window).resize(function() { adjustStyle($(this).width()); }); });
navigateLowerIE8.css文件就是IE8其低版本浏览器在缩小时的页面布局了。OK,一切都确实搞定。
