招牌文字特效

招牌文字特效

下面为效果显示

脚本说明:
第一步：把如下代码加入<body>区域中
<STYLE>.spanstyle {
	BACKGROUND-COLOR: #004400; BORDER-BOTTOM-STYLE: solid; BORDER-LEFT-STYLE: solid; BORDER-RIGHT-STYLE: solid; BORDER-TOP-STYLE: solid; COLOR: olive; FONT-FAMILY: 宋体; FONT-SIZE: 30px; HEIGHT: 90px; LEFT: -5000px; PADDING-BOTTOM: 5px; PADDING-LEFT: 5px; PADDING-RIGHT: 5px; PADDING-TOP: 5px; POSITION: absolute; TEXT-ALIGN: center; WIDTH: 280px
}
</STYLE>

第二步：把<body>中的内容改为：
<body bgcolor="#fef4d9" onload=changetext()>
