Cara Membuat Featured Post Image (Content Slider) Otomatis
BLOGGER menyediakan widget Featured untuk menampilkan postingan atau artikel blog yang menjadi unggulan di halaman depan atau sidebar.
"To help make it easier to showcase the posts you want your readers to see, we’ve created a new gadget called Featured Post. With Featured Post, you can choose posts you’ve shared on your blog and highlight them wherever you’d like," kata Google di Blogger Buzz.
Sebelum blogger menyediakan widget Featured itu, sudah banyak kode widget Featured Post dengan berbagai desain, seperti pernah CB share sebelumnya.
Kali ini CB share kembali kode Featured Content Slider (Featured Post) di halaman depan blog ini dari Maskolis dan Dynamic Drive dengan update "sedikit dimodifiksi" biar responsive dan fast loading. Demonya bisa dilihat di Sepakbola GP.
