Cara membuat teks bergerak melingkar

9:00 AM




mengikuti gerakan mouse atau dalam istilah bahasa Inggris dikenal dengan nama "Circling text trail". Teks tersebut akan bergerak melingkar mengelilingi pointer mouse disaat mouse sedang idle. Teks yang akan ditampilkan dapat diatur sesuai keinginan.

Yang perlu dilakukan adalah dengan memasukkan script di bawah ini ke dalam gadget html/javascript.






<style type="text/css">
/* Circle Text Styles */
/*http://www.dynamicdrive.com/dynamicindex13/circletext.htm */
#outerCircleText {
/* Optional - DO NOT SET FONT-SIZE HERE, SET IT IN THE SCRIPT */
font-style: italic;
font-weight: bold;
font-family: 'comic sans ms', verdana, arial;
color: #000;
/* End Optional */

/* Start Required - Do Not Edit */
position: absolute;top: 0;left: 0;z-index: 3000;cursor: default;}
#outerCircleText div {position: relative;}
#outerCircleText div div {position: absolute;top: 0;left: 0;text-align: center;}
/* End Required */
/* End Circle Text Styles */
</style>
<script type="text/javascript">

// Set font's style size for calculating dimensions
// Set to number of desired pixels font size (decimal and negative numbers not allowed)
