html星空特效代码简单(炫酷星空代码html)
html中可以星空的背景吗
可以的
例如下面这段代码
body{
background:?url(图片)?no-repeat?0?0?transparent;
background-size:?200%?auto;//防止图片不够大
}
html背景星星点点代码，仔细看图，就是这些点点一直闪闪发光，会的话请帮忙告诉我
去jay空间站找，有很多，空间设置，添加flash模块，粘贴上你要的模块地址，模块透明度全透明就可以了，随意设置大小，
向HTML代码里加入流星飞逝的代码
第一步：把 body改为： body bgcolor=#000000" onLoad="snow()"
第二步：加入
script language="JavaScript"
