1、媒體查詢

用法：@media (min-width:像素值) and (max-width: 像素值) {}
外鏈?zhǔn)剑?/p>

2实幕、bootsrap使用

官方鏈接：https://v3.bootcss.com/

首頁

 <link
      rel="stylesheet"
      href="./bootstrap-3.4.1-dist/css/bootstrap.min.css"
    />

引入jq+js文件

 <script src="./js/jquery.js"></script>
 <script src="./bootstrap-3.4.1-dist/js/bootstrap.js"></script>

布局以及樣式參考如圖：

今日案例：AlloyTeam響應(yīng)式網(wǎng)頁

考察點：boostrap運用 媒體查詢 less
目前做到：導(dǎo)航欄以及輪播圖區(qū)域
