Style Switcher Blog dengan Cookies

Style Switcher adalah aplikasi/aksesoris kecil yang biasa ada dalam sebuah situs untuk mengizinkan pengunjung mengganti tampilan dari luar sesuka hati. Dengan ini diharapkan pengunjung tidak akan bosan dengan artikel yang dia baca karena dia bisa memutuskan desain situs yang sedang dia kunjungi melalui Style Switcher.
Versi asli yang lebih besar sebenarnya cenderung mengambil konsep penggantian file CSS secara keseluruhan:

Di sini Saya hanya akan mengambil beberapa perubahan kecil saja seperti warna latar, warna huruf, jenis huruf dan ukuran huruf. Versi ini agak berbeda dengan yang biasa Anda temui, karena versi ini sudah Saya lengkapi dengan JavaScript Cookies.

Klik Simpan dan lihat hasilnya.
Kode yang Saya beri tanda adalah masa kadaluarsa kuki. Saya membuat masa kadaluarsa selama 7000 hari untuk membuat tampilannya bertahan selama mungkin. Tapi jika Anda ingin menentukan sendiri masa kadaluarsa perubahan tema yang pengunjung Anda lakukan, (misalnya tampilan yang telah berubah akan kembali menjadi seperti semula dalam waktu 3 hari), cukup ganti nilainya dari 7000 menjadi 3 (untuk 3 hari).

Catatan: Aksesoris ini cocok diterapkan pada tema yang sederhana, cenderung berkotak-kotak dan tidak memiliki detail elemen yang rumit. Tidak cocok untuk Blogazine.
Pertanyaan mengenai pengembangan dan penambahan fitur bisa dilanjutkan di bawah, tapi pastikan Anda sudah membaca cara kerja JavaScript Cookies sebelum berdiskusi » (pelajari di sini)
