Widget Top Komentator Dengan Avatar

                   Sebelumnya saya sudah pernah mengetengahkan tutorial membuat widget top komentator, kali ini masih masih akan mengetengahkan cara menambahkan widget yang sama namun sedikit perbedaan pada style. Widget top komentator sebelumnya hanya menampilkan nama dari komentator sedangkan widget kali ini menampilkan pula avatar dari komentator. Style tentunya bisa anda modifikasi lagi sesuai dengan keinginan anda, menambahkan efek howover pada avatar atau nama, menampilkan jumlah komentar atau pada jenis dan size link komentator.
Adapun kegunaan dari widget ini, bisa anda maknai sebagai apresiasi untuk pengunjung setia anda atau undangan untuk menarik perhatian dan keinginannya agar lebih giat berkomentar diblog anda.
Jika anda tertarik untuk menambahkan widget top komentator menarik dengan avatar ini, silahkan ikuti tutorial berikut:

• Pada dasbor –> Menu Tata Letak –> Tambah gadget HTML/JavaScript
• Beri title/judul yang anda inginkan dan Pada kolom konten masukkan kode berikut:  

<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>
