Cara Membuat Animasi Countdown Dengan CSS SVG

Halo, ketemu lagi dengan saya 🙂 apa kabarnya ? semoga baik yah, amin.

Pada kesempatan kali ini saya akan menjelaskan bagaimana caranyaÂ Membuat Animasi Countdown Dengan CSS SVG, ada yang tau apa itu countdown ? yah, countdown atau hitungan mundur biasanya kita lihat pada bumper pembuka video, nah kali ini saya akan membuat nya dengan SVG.

1. Silahkan buka dulu teks editornya kemudian ketikan kode HTML berikut.

<div class="demo">
  <div class="demo__colored-blocks">
    <div class="demo__colored-blocks-rotater">
      <div class="demo__colored-block"></div>
      <div class="demo__colored-block"></div>
      <div class="demo__colored-block"></div>
    </div>
    <div class="demo__colored-blocks-inner"></div>
    <div class="demo__text">Ready</div>
  </div>
  <div class="demo__inner">
    <svg class="demo__numbers" viewBox="0 0 100 100">
      <defs>
        <path class="demo__num-path-1" d="M40,28 55,22 55,78"/>
        <path class="demo__num-join-1-2" d="M55,78 55,83 a17,17 0 1,0 34,0 a20,10 0 0,0 -20,-10"/>
        <path class="demo__num-path-2" d="M69,73 l-35,0 l30,-30 a16,16 0 0,0 -22.6,-22.6 l-7,7"/>
        <path class="demo__num-join-2-3" d="M28,69 Q25,44 34.4,27.4"/>
        <path class="demo__num-path-3" d="M30,20 60,20 40,50 a18,15 0 1,1 -12,19"/>
      </defs>
      <path class="demo__numbers-path" 
            d="M-10,20 60,20 40,50 a18,15 0 1,1 -12,19 
               Q25,44 34.4,27.4
               l7,-7 a16,16 0 0,1 22.6,22.6 l-30,30 l35,0 L69,73 
               a20,10 0 0,1 20,10 a17,17 0 0,1 -34,0 L55,83 
               l0,-61 L40,28" />
    </svg>
  </div>
</div>

</div>

<div class="demo__text">Ready</div>

</div>

<defs>

</defs>

<path class="demo__numbers-path"

d="M-10,20 60,20 40,50 a18,15 0 1,1 -12,19

Q25,44 34.4,27.4

l7,-7 a16,16 0 0,1 22.6,22.6 l-30,30 l35,0 L69,73

a20,10 0 0,1 20,10 a17,17 0 0,1 -34,0 L55,83

l0,-61 L40,28" />

</svg>

</div>

2. Setelah itu lanjutkan untuk kode CSS SVG nya.
