第一步:把如下代码加入<head>区域中

第二步：把如下代码加入到<body>区域中
<div id="sparks">
<div id="sDiv0" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="red">欢</font></div>
<div id="sDiv1" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="yellow">迎</font></div>
<div id="sDiv2" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="blue">光</font></div>
<div id="sDiv3" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="red">临</font></div>
<div id="sDiv4" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="orange">e</font></div>
<div id="sDiv5" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="white">f</font></div>
<div id="sDiv6" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="green">g</font></div>
<div id="sDiv7" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="skyblue">h</font></div>
<div id="sDiv8" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="yellow">i</font></div>
<div id="sDiv9" style="position:absolute; visibility: hidden;"><font
face="arial black"
color="white">j</font></div>
</div>
第三步：把“OnLoad="initMouseEvents()"”加在<body>标记里
例如：<body OnLoad="initMouseEvents()">
