Membuat Tombol Facebook, Twitter dan Google+ Melayang

Sebelumnya kita membuat tombol facebook, twitter dan Google+ pada halaman posting atau disidebar, namun kali ini kita akan membuat tombol tersebut melayang dan akan bergeser ketika pengguna mengscroll halaman ke atas atau bawah. Trik yang satu ini akan menambah efek pada halaman blog anda sehingga tampak lebih indah. Kita akan menggunakan kode Javascript untuk membuat widget yang satu ini. Caranya sangat mudah, jika sobat ingin membuatnya ikuti langkah berikut ini:

1. Login ke Blogger
2. Masuk ke Rancangan -- Elemen Halaman
3. Tambahkan gadjet lalu pilih HTML/JavaScript
4. Masukkan kode berikut ini:

<style>
/*-------Blogtrikdantips Tombol Melayang------------*/
#floatdiv {
position:absolute;
width:94px;
height:229px;
top:0;
left:0;
z-index:100
}

#bttsidebar {
border:1px solid #ddd;
padding-left:5px;
position:relative;
height:220px;
width:55px;
margin:0 0 0 5px;
}
</style>


<div id="floatdiv">
<div id="bttsidebar">
<table cellpadding="1px" cellspacing="0">
