- Bootstrap
Second, the Bootstrap
1.Concept: A front-end development framework, Bootstrap, from Twitter, is currently a popular front-end framework. Bootstrap is simple and flexible based on HTML, CSS, and JavaScript, making Web development faster. *Framework: a semi-finished software that developers can develop on the basis of the framework to simplify coding. *Benefits: 1.Defines a number of CSS styles and JS plug-ins. We developers can use these styles and plug-ins directly 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 the Bootstrap 2.Copy the three folders (CSS/JS/Fonts) in your project 3.Create an HTML page and import the necessary resource files<! DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <! The above 3 meta tags must come first, and everything else must come after them! --> <title>Bootstrap HelloWorld</title> <! -- Bootstrap --> <link href="css/bootstrap.min.css" rel="stylesheet"> <! <script SRC ="js/jquery-3.2.1. Min.js "></script> <! Load all JavaScript plugins for Bootstrap. You can also load individual plug-ins as needed. --> <script SRC ="js/bootstrap.min.js"></script> </head> <body> <h1> Hello world! </h1> </body> </html>Copy the codeResponsive layout
*The same set of pages can be compatible with devices of different resolutions. *Implementation: Depends on the grid system: divide a row evenly into 12 cells. You can specify how many cells the elements occupy *Step (The class of the ** tag specifies **) : 1.Define the container. Equivalent to table, *Container classification: 1.Container: Leave white on both sides 2.Container-fluid: Each device is 100% width 2.Define line. Equivalent to the tr style before: row 3.Define elements. Specifies the number of cells this element occupies on different devices. Style: COL - Equipment code - number of cells *Equipment Code: 1.Xs: Ultra-small screen phone (<768px) : COL-XS-12 2.Sm: Small screen tablet (≥768px) 3.Md: Medium screen desktop monitor (≥992px) 4.Lg: Large screen large desktop monitor (≥1200px) *Note: 1.If there are more than 12 cells in a row, the excess part is wrapped. 2.Raster class attributes can be upwardly compatible. The grid class works with devices whose screen width is greater than or equal to the size of the cut-off point (that is, small device elements occupy the same grid as large devices). 3.If the true device width is less than the minimum value of the device code that sets the raster class attributes, an element can be smeared across an entire line.Copy the code4. CSS styles and JS plug-ins (Reference documentation)
1.Global CSS styles: *Button: class=" BTN btn-default" *Image: *Class ="img-responsive" : the image is 100% in any size *Image shape * <img src="..." alt="..." class="img-rounded">Square: * <img src="..." alt="..." class="img-circle">Round: * <img src="..." alt="..." class="img-thumbnail">: a picture frame *form * table
* table-bordered
* table-hover
*The form *Add class="form-control" to the form entry 2.Components: *Navigation bar (you can delete to know the function of each label) *Article page 3.Plug-in: *Shuffling figureCopy the codeFive, the case
