Jam analog, digital menggunakan CSS & JavaScript

Edit

Membuat jam analog dengan CSS tidak lagi menjadi tugas berat. New HTML5 dan CSS properti telah membuat halaman web lebih ringan tapi kaya fungsi.

Ok, Mari kita mulai coding.

1. Membuat HTML
Pertama, kita perlu menciptakan 60 menit dari jam dengan li elemen ul (unordered list). Beri nama kelas div sebagai 'menit-tanda'. Dari 60 menit, 48 akan menjadi tanda centang menit antara jam dan 12 elemen li untuk menunjukkan angka dari 1-2-3 - ... -12.

Juga, tambahkan div individu untuk menunjukkan jam, menit dan detik tangan, seperti yang ditunjukkan di bawah ini. 
<div id="watch">
  <div class="frame-face"></div>
  <ul class="minute-marks">
  <li></li><li></li><li></li><li></li><li></li><li></li>
  <li></li><li></li><li></li><li></li><li></li><li></li>
  <li></li><li></li><li></li><li></li><li></li><li></li>
  <li></li><li></li><li></li><li></li><li></li><li></li>
  <li></li><li></li><li></li><li></li><li></li><li></li>
  <li></li><li></li><li></li><li></li><li></li><li></li>
  <li></li><li></li><li></li><li></li><li></li><li></li>
  <li></li><li></li><li></li><li></li><li></li><li></li>
  </ul>
  <div class="hours-hand"></div>
  <div class="minutes-hand"></div>
  <div class="seconds-hand"></div>
</div>
Bukankah lebih baik jika kita menunjukkan Jam Digital lain di dalam jam Analog. Ok, mari kita tambahkan satu set divs untuk menampilkan jam digital.
  <div class="digital-wrap">
  <ul class="digit-hours">
