Using Bootstrap to build responsive web pages

1, to establish a responsive site layout, this time bootstrap high-level can be reflected.

2, first to understand what Bootstrap provides the response tools for us to use:

(1) The concept of screen width size:

<768PX Ultra small screen (mobile)

768px>= <992px small screen (tablet)

992px>= <1200px Medium screen (desktop)

>=1200px large screen (desktop)

(2) You can hide or show page content for different screen sizes by using the classes listed below individually or jointly

Hidden when the face does not have the * number, when displayed with a * number. This is because the display is divided into block, inline-block and inline three cases. Hide is none, so do not take the * number.
