twitter-bootstrap – Bootstrap 3个断点和媒体查询

在 http://getbootstrap.com/css/它说：

We use the following media queries to create the key breakpoints in
our grid system.

Extra small devices (phones,up to 480px):
No media query since this is the default in Bootstrap

Small devices (tablets,768px and up):
@media (min-width: @screen-sm) { … }

Medium devices (desktops,992px and up):
@media (min-width: @screen-md) { … }

Large devices (large desktops,1200px and up):
@media (min-width: @screen-lg) { … }

我们应该能够在我们的媒体查询中使用@ screen-sm，@ screen-md和@ screen-lg名称吗？因为它不适合我。我必须使用像素测量，如@media(min-width：768px){…}，然后才能工作。我做错了什么？

此外，对于额外的小设备的打字错误的参考480px？不应该说高达767px？

解决方法

@nickforthought给出Bootstrap 3的最佳摘要，我们可以申请无Bootstrap我总是使用他的参考在我的工作中实现。
