1.你的輪播圖沒(méi)顯示是因?yàn)槟愕腸ss代碼有一部分注釋無(wú)效引起。
}<!--以上頭部部分--> .nav { height:40px; }你的注釋<!--以上頭部部分-->后半部分無(wú)效了，結(jié)果導(dǎo)致.nav這個(gè)樣式無(wú)效，然后導(dǎo)航欄就沒(méi)有高度~
解決辦法就是?
你的注釋改成：<!--以上頭部部分 -->
（改動(dòng)部分是“部分”后面加個(gè)空格）
或者直接刪掉這個(gè)注釋。
2.顏色顯示不了是因?yàn)槟愕腸ss代碼news的沒(méi)有背景色樣式
.news { width:340px; border:1px?solid?#E8E8E8; }只有寬度和邊框，沒(méi)背景色，所以當(dāng)然就沒(méi)顯示背景，只顯示了最外層main的背景色。

你可以下載一下老師的那個(gè)資源代碼，對(duì)比一下
