tailwind gauge chart

tailwind-gauge-chart.html

<!-- percent to deg => Math.round(((value / 100) * 180 - 45) * 10) / 10 -->

<div class="relative flex aspect-[2] items-center justify-center overflow-hidden rounded-t-full bg-blue-400">
  <div class="absolute top-0 aspect-square w-full rotate-[calc(72deg-45deg)] bg-gradient-to-tr from-transparent from-50% to-white to-50% transition-transform duration-500"></div>
  <div class="absolute top-1/4 flex aspect-square w-3/4 justify-center rounded-full bg-blue-100"></div>
  <div class="absolute bottom-0 w-full truncate text-center text-[20vmax] leading-none">40%</div>
</div>

Apparently, I just need to nested it and with a bit modification it can become like this

<div class="relative flex aspect-[2] items-center justify-center overflow-hidden rounded-t-full">
  <!-- outer ring -->
  <div class="absolute aspect-square top-0 w-full rotate-[calc(100deg-45deg)] bg-gradient-to-tr from-green-400 from-50% to-transparent to-50% transition-transform duration-500"></div>
  <div class="absolute aspect-square top-0 w-full rotate-[calc(100deg-45deg)] bg-gradient-to-tr from-transparent from-50% to-yellow-400 to-50% transition-transform duration-500"></div>
  <div class="absolute aspect-square top-0 w-full rotate-[calc(140deg-45deg)] bg-gradient-to-tr from-transparent from-50% to-red-400 to-50% transition-transform duration-500"></div>
  
  <!-- actual gauge -->
  <div class="absolute inset-8 flex aspect-[2] items-center justify-center overflow-hidden rounded-t-full border-4 border-b-0 border-slate-600">
    <div class="absolute aspect-square top-0 w-full rotate-[calc(72deg-45deg)] bg-gradient-to-tr from-blue-400 from-50% to-transparent to-50% transition-transform duration-500"></div>
    <div class="absolute aspect-square top-0 w-full rotate-[calc(72deg-45deg)] bg-gradient-to-tr from-transparent from-50% to-blue-100 to-50% transition-transform duration-500"></div>
    <div class="absolute top-1/4 flex aspect-square w-3/4 justify-center rounded-full bg-blue-100"></div>
    <div class="absolute bottom-0 w-full truncate text-center text-8xl leading-none">40%</div>
  </div>
</div>

And for separation we just need to control the border.

@aryomuzakki Thanks for sharing! 🙏
