Bootstrap:
1. Concept: A framework for front-end development, Bootstrap, from Twitter, is currently a popular front-end framework.Bootstrap is based on HTML, CSS, JavaScript. It is simple and flexible, making Web development faster.
*Framework: A semi-finished software on which developers can develop and simplify coding.
*Benefits:
1. There are many css styles and js plug-ins defined.These styles and plug-ins can be used directly by our developers to get rich page effects.
2. Responsive layout.
*The same set of pages can be compatible with devices of different resolutions.2. Quick Start
1. Download Bootstrap
2. Copy these three folders in the project
3. Create html pages and introduce necessary resource files <!DOCTYPE html>

Hello, World!</h1>
</body>
</html>Responsive Layout
*The same set of pages can be compatible with devices of different resolutions.
*Implementation: depends on the raster system: divide a row into 12 grids on average, and you can specify elements to occupy several grids
*Step:
1. Define containers.Equivalent to previous table s,
*Container Classification:
1. container: leave blank on both sides
2. container-fluid: each device is 100% wide
2. Define rows.Equivalent to the previous tr style:row
3. Define elements.Specifies the number of cells the element occupies on different devices.Style: col-device Code-Number of grids
*Device code number:
1. xs: ultra small screen mobile phone (<768px):col-xs-12
2. sm: small screen flat panel (> 768px)
3. md: Medium screen desktop display (> 992px)
4. lg: Large screen large desktop display (> 1200px)
*Note:
1. If the number of cells in a line exceeds 12, it exceeds the automatic line wrapping portion.
2. Raster class properties can be upward compatible.Raster classes are suitable for devices with screen widths greater than or equal to the size of the boundary point.
3. If the true device width is less than the minimum value of the device code for setting raster class properties, an element will be contaminated with a whole line.CSS Styles and JS Plugins
