</script>
<style type='text/css'>
.titlefield{ /*CSS for RSS title link in general*/
text-decoration: none;}
.labelfield{ /*CSS for label field in general*/

#example1 a:hover {color:#111;text-decoration:none;}
</style>

6. Untuk meletakkan headline news diatas judul posting cari kode <div id='outer-wrapper'> kemudian letakkan kode berikut sebelumnya:

<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://Alamat URL Blog Anda/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>

Keterangan:

Kode 840px = Panjang background gambar headline news, sesuaikan dengan lebar blog anda.
Kode 125px = Jarak judul artikel dari sebelah kiri gambar.
Kode 10      = Jumlah entri judul artikel yang akan ditampilkan.

7. Simpan jika sudah selesai dan lihat hasilnya pada halaman hompage blog anda, apabila anda sudah benar dalam meletakkan kodenya maka Headlines News akan mucul tanpa masalah.
