6. Kemudian kita akan meletakkan news sticker tersebut diatas posting dan sidebar seperti posisi news sticker milik saya, caranya yaitu cari kode <div id='outer-wrapper'>

7. Setelah itu paste kode berikut diatas kode <div id='outer-wrapper'>

<div style='clear:both;'/>

<div class='newspic'>
<div style='float:left;width:780px;padding:6px 0 6px 125px; position:relative; overflow:hidden;'>
<script type='text/javascript'>
var cssfeed=new gfeedrssticker(&quot;example1&quot;, &quot;example1class&quot;, 4000, &quot;_new&quot;)
cssfeed.addFeed(&quot;Creating Website&quot;, &quot;http://ko2.blogspot.com/feeds/posts/default&quot;) //Specify &quot;label&quot; plus URL to RSS feed
cssfeed.displayoptions(&quot;date&quot;) //show the specified additional fields
cssfeed.setentrycontainer(&quot;div&quot;) //Wrap each entry with a DIV tag
cssfeed.filterfeed(10, &quot;date&quot;) //Show 10 entries, sort by date
cssfeed.entries_per_page(1)
cssfeed.init()
</script>
</div>
<div style='clear:both;'/>
</div>

8. Ganti kode berwarna merah dengan url blog anda
