   .newspic {background:#000 url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhwTQL-mj54FFlrQf_wbwtzAtUlSYXJ5WIjA3aCBwutVKlqkYijmO0F8gRxdNOzahDM8mZYFxeJ9JIWMhd15iINuDnt9SZmz4174xyTjgtrwih5iC4QYKgw6gdVIVMIvUugQBKWgwyUeEc/s1600/news.gif) no-repeat top left;width:100%;margin:0 auto;padding:0 auto;height:32px;color:#fff;}
   .news {width: 100%;margin:0 auto;padding:0 auto;line-height: 1.4em;text-align:left;font-family:Arial;font-size:11px;color:#fff;overflow:hidden;clear:both;}
   .news a:link, .news a:visited{color:#fff;text-decoration:none;}
   .news a:hover {color:#ddd;text-decoration:underline;}

    Keterangan :
   > Warna merah adalah ukuran lebar/panjang headline news.
   > Warna hijau adalah ukuran tinggi headline news.

6. Terakhir cari kode   <div id='header-wrapper'> atau   <div id='header-outer'> header-outer atau (pilih salah satu saja) 
7. Lalu letakkan kode berikut tepat di bawah kode nomor 6 tadi
   
   
    <div class='newspic'>
   <div style='float:left;width:780px;padding:6px 0 6px 180px; position:relative; overflow:hidden;'>
