Membuat Widget Top Komentator di Blogger

Widget top komentator berguna untuk menampilkan para komentator di blog kita dari mulai yang terbanyak komentarnya. Dengan menampilkan link komentator, maka mereka akan lebih giat lagi untuk memberikan komentar di blog kita. Kekurangan dari script ini loading
nya terasa lama ketika komentar sudah mencapai ribuan.

Script ini dibuat oleh MS Postilas, dan sudah saya edit sedikit CSS nya, sehingga sedikit berbeda dengan tampilan aslinya.

Bagi sahabat yang ingin menampilkan Widget Top Komentator, silahkan simak langkah mudahnya :

1. Login ke Dasbor Blogger
2. Tambahkan widget HTML/JavaScript, simpan kode ini :

<style type="text/css">
.top-commenter-line img {
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
margin-left:5px;margin-right:5px;
}
.top-commenter-line {margin: 5px 0;border-bottom:1px solid #eee;padding:3px 5px 6px 0px;}
.top-commenter-line .profile-name-link {padding-left:0;font-weight:bold;}
.top-commenter-avatar {vertical-align:middle;width:30px;height:30px;
}
</style>
<script type="text/javascript">

3. Simpan Widget

Untuk kostumisasi, silahkan lihat CONFIG pada script di atas. Jangan lupa ganti "Kang Ismet" dengan nama sobat, supaya komentar sobat tidak masuk pada top komentator.

Apabila sobat ingin menghilangkan jumlah komentar, seperti tampilan dibawah :

hapus kode ([count]) pada script di atas. Semoga bermanfaat...
