首先,我们从动望的默认CSS来解释,这个是默认的default.css一:/* copyright 2007 dvbbs, all rights reserved.*//* 全局定义 */html, body { background: #fff url("../images/bodybg.gif") repeat-x; color: #333; line-height:18px; }这个地方我们可以定义论坛的背景颜色 background: #fff url("../images/bodybg.gif") repeat-x; #fff就是颜色,你可以改个颜色,url("../images/bodybg.gif") repeat-x;背景图片,你把这个图片换个看看效果,当然,您也可以不使用图片,那么可以把 url("../images/bodybg.gif") repeat-x删除,然后修改background: #fff中的颜色代码,刷新首页看下效果吧~ 这个是论坛整体文字的颜色：color: #333html, body, h1, h2, h3, h4, ul, li, dl, input { font-family:Arial, Helvetica, sans-serif; font-size:12px; list-style:none; margin:0px;padding:0px; }div, p{ font-family:Arial, Helvetica, sans-serif; list-style:none; margin:0px;padding:0px; }div, table {margin: 0 auto; }a { color:#0365BF; text-decoration: none; }color:#0365BF这里是论坛有连接的文字颜色text-decoration: none;无属性a:hover { color:#f60; text-decoration: underline; }color:#f60有连接文字鼠标悬停后的颜色text-decoration: underline;属性带下划线hr { height:0px; border:0px; border-bottom:1px solid #E7F0F5; }这个用在很多地方,比如友情连接中间那条线的颜色img { border:0px; vertical-align: middle; }.chkbox,.checkbox, .radio, button, input, select,textarea { vertical-align: middle; font-size:12px; }.radio {border:none;}二:/* font style */.white, .white a { color:white; }.white a:hover { color:#ff7; }.grey, .grey a, a.grey { color:#858D92; }.green, .green a { color:#008000; }.yellow, .yellow a { color:#f60; }a.yellow:hover, a.green:hover { color:#666; }.font10 { font-size:11px;
