默认情况下，body，ul 等标签有margin，padding值，需要重置一下默认值。
html, body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, code, form, fieldset, legend, input, button, textarea, p, blockquote, th, td, tbody {list-style:none; margin:0px; padding:0px; }
在你的css加上
body{ margin:0; padding:0; font:12px/1.5 Microsoft YaHei;background:#f2f2f2}
h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, cite, code, img, small, strike, sub, sup, tt, dd, dl, dt, li, ol, ul, fieldset, form, label, legend, button, table, caption, tbody, tfoot, thead, tr, th, td { margin: 0; padding: 0; border: 0; }
input{background:none;border:none;}
ul , li { list-style:none;}
默认情况下，body，ul 等标签有margin，padding值，需要重置一下默认值。
margin，padding设置成0就行了。另外样式也设置成none
.shopzp ul{margin:0; padding:0; float:left; clear:both;}
*{margin:0;padding:0;}改变所有属性的默认样式的内外编剧都为0，就可以了~
谢谢大家了 已经解决了
