Membuat Tabbed Panel

Baiklah kali ini saya akan share cara membuat tabbed panel yang akan mempercantik tampilan blog sobat. Sudah pada tahu semua kan apa itu tabbed panel? Yaitu widget yang ada di sidebar blog ini, lihat gambar. Dalam tabbed panel itu saya isi dengan Posting acak, posting populer, dan komentar terakhir.

Sobat juga bisa mengisi nya dengan isi yang sama dengan saya di atas, atau sobat juga bisa menambahkan sendiri isi yang ingin sobat tambahkan. Langsung saja ini dia caranya untuk membuat tabbed panel :

1. Buka akun blogger sobat, pergi ke Tata Letak (tampilan blogger baru).
2. Tambahkan Gadget HTML/ Javascript.
3. Copy paste script di bawah ini ke dalam isi widget tersebut.

4. Kalau sudah simpan widget tersebut.

Keterangan :

JUDUL TAB silakan diisi dengan judul tiap tab, misal Latest Post, Popular Post atau Comment.
ISI TAB silakan diisi dengan isi tiap tabbed panel tersebut.

Selesai sudah pembuatan widget Tabbed Panel, jika ada yang kurang jelas silakan ditanyakan lewat komentar.
