就CSS和什么不去，查看原始来源显示以下内容：
<html><head><style>body { background-color: #F2F2F2; font-family: Arial; color: #5C5C5C; font-size: 11pt; } a { color: #46AAFF; text-decoration: none; } #container { width: 750px; margin-right: auto; margin-left: auto; } #header { float: right; padding: 3px; height: 30px; } #header a { color: #666666; margin-right: 10px; } #mainBody { padding: 20px; background-color: #FFF; border: 1px solid #DADADA; border-radius: 3px; } #imageArea { border-top: solid #E8E8E8 1px; margin: 15px; } #singleImageArea { width: 250px; padding: 15px; } #singleImageArea p { float: right; line-height: 30px; width: 130px; margin-top: 20px; } #footer { padding: 10px; color: gray; } #footer p { text-shadow: 0px 2px #FFF; font-size: 10pt; } #footer a { color: #ADADAD; float: right; padding-left: 20px; padding-right: 20px; } #footer img { width: 35px; height: 23px; padding: 10px; float: left; } </style></head><body><div id="container"><div id="header"><a href="http://appname.local/login/">Login</a></d
