Menyambut Natal tahun 2014 bagi yang merayakan, eksperimen ini layak anda uji coba di website dan blog anda. Dengan teknologi CSS3 dan browser modern (Firefox, Chrome, Safari, Opera) kita bisa menikmati animasi pohon natal yang unik tanpa menggunakan library tambahan seperti Flash atau GIF. Siapkan, file HTML yang akan disisipi animasi ini. Tambahkan baris berikut: [sourcecode language="html"] <div id="container"> <div id="tree"> <div class="layer"> <div></div> <div></div> <div></div> <div></div> <div></div> </div> <div class="layer"> <div></div> <div></div> <div></div> <div></div> <div></div> </div> <div class="layer"> <div></div> <div></div> <div></div> <div></div> <div></div> </div> <div class="layer"> <div></div> <div></div> <div></div> <div></div> <div></div> </div> </div> </div> [/sourcecode] Kemudian tambahkan style CSS3 berikut pada file CSS anda: [sourcecode language="css"] /* Copyright (c) 2010 Sebastien P. http://twitter.com/_sebastienp MIT licensed. --- A full CSS 3D rotating Christmas tree using CSS3 animation, transforms, gradients etc. The text size can be adjusted to make the tree zoom in.
