摘要：基本思路: 首先將頁面頭部的導航條樣式，其中class名為header_left；再將下拉菜單的小米手機下拉菜單做出，之后的上方下拉菜單處可以借鑒相同的代碼部分，其中class名為contentMenu_ul_li1；再做出側邊欄豎導航，同樣可以先做手機電話卡第一個部分，再在下面使用相同class名contentPic_l_Phone，使用圖片時再改相
基本思路:
首先將頁面頭部的導航條樣式，其中class名為header_left；再將下拉菜單的小米手機下拉菜單做出，之后的上方下拉菜單處可以借鑒相同的代碼部分，其中class名為contentMenu_ul_li1；再做出側邊欄豎導航，同樣可以先做手機電話卡第一個部分，再在下面使用相同class名contentPic_l_Phone，使用圖片時再改相關的路徑，做出大致樣式；最后一部分導航條是頁面中的小導航條，思路也是做出一部分再之后直接用做出的代碼即可。
注意事項：
做頁面的導航條時，很多部分都是類似的，可以重復利用，使做出頁面時能更加簡便。
引用圖片路徑時，要注意圖片的格式是jpg還是png，這樣頁面才能加載出圖片。
在做手機部分后面的導航部分時，現(xiàn)在引用i標簽將圖標引用進來，再在外面套置一span標簽，將其改變成塊級元素，并通過css設置多種樣式使之產生圓形陰影樣式，并通過偽屬性使其產生相關效果。

老師總結：導航布局常見的效果是下拉菜單。原理是通過css的hover來控制元素的顯示與隱藏
