</html>求解：1.教程里邊的源碼并沒有設(shè)置ul的border；
? ? ? ? ? 2.為什么我的全局聲明*{margin:0;padding:0}對(duì)ul無效了，還要單獨(dú)設(shè)置margin-bottom:0;
說明：1.如果我不設(shè)置ul的border就做不大無縫滾動(dòng)；
? ? ? ? ? 2.不設(shè)置margin-bottom，兩個(gè)ul間有間距；
望大神解答，萬分感謝！！

加了border反而滾一圈就滾不動(dòng)了，不加border就可以，不過會(huì)突然跳一下。
就是因?yàn)榧恿薭order所以兩個(gè)ul有間距。
