更新! - 我将媒体查询设置为
@@media only screen and (max-width : 767px)
.text-left
text-align: center;
当我打开 Chrome 时,它工作正常。但是,如果我在默认窗口大小约为 900 像素时打开 IE 11,则文本居中(不好)。仅供参考 - 如果我稍微调整窗口大小,文本会重新对齐到左侧!这是一个奇怪的 IE 错误吗??
【问题讨论】:
你能查一下@@media
吗,因为它会是@media
。
检查此问题后,您需要将@@media
的拼写错误解决为@media
。
检查这个链接它运行良好 IE 11 copen_link
请查看此链接:-css-tricks.com/snippets/css/media-queries-for-standard-devices
【参考方案1】:
@media all and (max-width : 768px)
.text-left
text-align: center;
【讨论】:
【参考方案2】:不是@@media
,而是@media
。
@media all and (min-width: 768px)
.text-left
text-align: center;
【讨论】:
我使用的是 ASP.Net MVC,它是 @@media,而不是 @media 很高兴您在问题中提到了这一点并否决了我的回答。看看你自己的小提琴,使用@media
。它按预期工作。 jsfiddle.net/fht0wtwp/1
我想我更关心的是 IE 和 Chrome,尽管我在原始帖子中没有提到它。它在 Chrome 中运行良好,但如果我打开 IE 并以 850px 的位置开始页面,则文本居中(不好),如果我稍微调整窗口大小,则会适当地重新设置文本(左对齐)。为什么 thios 只在 IE 而不是 Chrome?【参考方案3】:
对于小型设备,您不能使用min-width
。
指定所有 Min 和 Max 的最佳方式。
@media all and (max-width: ***px) and (min-width: ***px)
更多示例:
@media only screen and (min-width: 768px)
/* Tablets and Desktop */
@media only screen and (max-width: 767px)
/* Phones */
@media only screen and (max-width: 767px) and (orientation: portrait)
/* Portrait Phones */
您是否担心所有和仅屏幕?

好的,所以我只使用@media 屏幕和(最大宽度:767px),它在 Chrome 中运行良好,但是当我在 IE 11 中打开它时,即使屏幕更大,文本也会居中767 像素。为什么 IE 表现得很时髦,但 Chrome 没问题? 如果我稍微调整一下屏幕大小,文本会变回左对齐!这是一个奇怪的 IE 错误吗? 给我一点时间,让我了解您的问题的更多信息【参考方案4】:您是否设置了视口元标记?
<meta name="viewport" content="width=device-width, initial-scale=1">
如果未设置此标签,媒体查询将无法正常工作。
