CSS3 Media Queries 片段

Responsive设计在现代Web设计中可谓是越来越流行，但很同学们并未理解其真正的设计概念，往往把Responsive视为一种自适应布局。当然有很多同学也在尝试动写Responsive的案例，但如何取其断点左右纠结，如何设置哪几个断点？又从何入手？

Responsive中的断点都依赖于CSS3的Media Queries来决断，今天特意根据一些Responsive框架整理了一些常见的Media Queries片段，以供大家参考：

CSS3 Media Queries片段

在这里主要分成三类：移动端、PC端以及一些常见的响应式框架的Media Queries片段。
