Heroicons

The heroicons page (opens in a new tab) is a great source of icons for your pages. The width attribute helps to fix the size of the icon.

<svg
  className="h-6 w-6 text-gray-500"
  fill="none"
  viewBox="0 0 24 24"
  stroke="currentColor"
  strokeWidth="2"
  width="50" 
>
  <path
    strokeLinecap="round"
    strokeLinejoin="round"
    d="M12 8v4l3 3m6-3a9 9 0 11-18 0 9 9 0 0118 0z"
  />

Thanks for asking. I got it fixed at last. It just that the SVG sizing is a bit confusing, making the size bigger, makes the icon smaller. :-)
