Bootstrap需要引的三个文件
<link rel="stylesheet" href="css/bootstrap.css"> 表格元素的样式
<script type="text/jscript" src="js/bootstrap.js"></script> bootstrap动画
<script type="text/jscript" src="js/jquery-3.4.0.min.js"></script> javascript库
bootstrap最大的系统就是响应系统(栅格系统 )
<meta name="viewport" content="width=device-width, initial-scale=1"> 绘制和触屏缩放，需要在 <head> 之中添加 viewport 元数据标签。
<!DOCTYPE html>
