使用rem和em為單位(除部分margin和padding使用px) 使用push和pull向左右移動 偏移列通過offset-類設置 使用float的布局方式 選擇彈性盒模型(flexbox) 注:Bootstrap3的4種柵格: 特小(col-xs-) 適配手機(<768px) 小(col-sm-) 適配平板(≥768px) 中(col-md-) 適配電腦(≥992px) 大(col-lg-) 適配寬屏電腦(≥1200px) Bootstrap4的5種柵格: 特小(col-)(<576px) 小(col-sm-)(≥576px) 中(col-md-)(≥768px) 大(col-lg-) (≥992px) 特大(col-xl-)(≥1200px) **混用案例:** >[info]當屏幕尺寸 小于 768px 的時候,用 col-xs-12 類對應的樣式; 在 768px 到 992px 之間的時候,用 col-sm-9 類對應的樣式; 在 992px 到 1200px 之間的時候,用 col-md-6 類對應的樣式; 大于 1200px 的時候,用 col-lg-3 類對應的樣式; ~~~ <div class="col-xs-12 col-sm-9 col-md-6 col-lg-3"> </div> ~~~ **Bootstrap4特點** 新增網格層適配了移動端; 全面引入ES6新特性(重寫所有JavaScript插件); css文件減少了至少40%; 所有文檔都用Markdown編輯器重寫; Bootstrap4 放棄了對 IE8 以及 iOS 6 的支持,現在僅僅支持 IE9 以上 以及 iOS 7 以上版本的瀏覽器。如果對于其中需要用到以前的瀏覽器,那么請使用[Bootstrap3](https://www.runoob.com/bootstrap/bootstrap-tutorial.html)。 推薦框架[Free Bootstrap Admin Template - AdminLTE.IO](https://adminlte.io/) [Treeview Plugin |
