1、BootStrap 快速了解

BootStrap ：别人帮我们写好的CSS样式，如果想要使用这个 BootStrap 需要下载
使用方式：

下载BootStrap
使用BootStrap ：
- 在页面中引入 BootStrap ；
- 编写HTML时，按照 BootStrap 的规定来编写或自制

2、初识BootStrap

2.1 下载地址

BootStrap v3 中文文档
在这里插入图片描述

css文件夹：

以上都是写好的 CSS 文件

2.2 创建目录

下载后首先创建必要的目录：
在这里插入图片描述
一般项目中会创建 static 目录，并在 static 目录中创建 css、img、js、plugins 目录，存放css文件、图片文件、js文件、项目用到的插件。

2.3 引入BootStrap

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <!-- HTML注释：开发版本 -->
    <link rel="stylesheet" href="static/plugins/bootstrap-3.4.1/css/bootstrap.css">

    <!-- 生产版本 -->
    <link rel="stylesheet" href="static/plugins/bootstrap-3.4.1/css/bootstrap.min.css">

3.2 栅格系统

在这里插入图片描述
栅格系统把整体划分为了12格

大致分为四种风格：

.col-xs-
.col-sm-
.col-md-
.col-lg-

又分为：

响应式：根据页面的宽度,动态的改变布局，区别在于像素不同
- .col-sm- : 750px
- .col-md- : 970px
- .col-lg- : 1170px
非响应式
- .col-xs-

在这里插入图片描述
页面中引入栅格：

3.8.4 触发跳转

通过 data-toggle="modal" 属性进行跳转，当点击按键时，会寻找带有id=myModal的标签，同理可以将注册按键设置触发点击跳转

            <ul class="nav navbar-nav navbar-right">
                <li><a href="#">Link</a></li>
                <li><a href="#">登录</a></li>
                <li><a href="#" data-toggle="modal" data-target="#myModal">注册</a></li>
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true"
                       aria-expanded="false">Dropdown <span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Action</a></li>
                        <li><a href="#">Another action</a></li>
