响应式网页设计是设计和构建网站的过程，为用户提供更好的可访问性和***观看体验。



随着智能手机和平板电脑的发展趋势，忽略移动设备网站的优化几乎是不可避免的。响应式网页设计是一种更好的替代方案，也是一种以更少的努力瞄准各种设备的有效方式。



因此，bootstrap不是关于移动设备或桌面上的响应式设计，而是关于响应式设计各种不同的屏幕分辨率。

"Responsive web design is a process of designing and building websites to provide better accessibility and optimal viewing experience to the user.

With the growing trend of smart phones and tablets, it has become almost unavoidable to ignore the optimization of sites for mobile devices. Responsive web design is a preferable alternative and an efficient way to target a wide range of devices with much less efforts."

So bootstrap is not about responsive design on a mobile or desktop, but rather about responsive design to a wide variety of different screen resolutions.
