How to make 3 transparent holes using Radial-gradient inside -webkit-mask but keep the image

Question

I'm working on a project where I need to make a div that must have 3 random holes on its border to make it transparent.

The problem I am facing is that for 2 holes I am using -webkit-mask with radial gradient to create 2 transparent holes of 20px. My question is when I try to create a third hole, does anyone know how to do this?

I have attached an image with the model that I need to copy. What I want is this, make 3 holes in the div

Create more complex masks using the mask-composite property:

Answer 2

You can combine multiple radial-gradient to create more "holes" or effects, please refer to This solution I posted two days ago, aimed at creating multiple A "loophole".

The next challenge will be shadows, but prefer using filter: drop-shadow and wrapper components. box-shadow does not apply to -webkit-mask / mask.

---

Here is an example of building a ticket-like element in pure CSS:

.wrapper {
  filter: drop-shadow(0 0 4px rgba(0, 0, 0, 0.5));
  width: 200px;
  height: 300px;
}

.ticket {
  box-sizing: border-box;
  border-radius: 20px;
  background: white;
  width: 200px;
  height: 300px;
  -webkit-mask-image:
    radial-gradient(circle at 0% 55%, transparent 5%, black 5%, black 33%, transparent 33%), /* Left hole */
    radial-gradient(circle at 100% 55%, transparent 5%, black 5%, black 33%, transparent 33%), /* Right hole */
    radial-gradient(circle at 50% 0%, transparent 7%, black 7%, black 40%, transparent 40%), /* Top hole */
    radial-gradient(circle at 50% 50%, black 0%, black 33%, transparent 33%), /* Middle filling */
    radial-gradient(circle at 50% 100%, black 0%, black 40%, transparent 40%); /* Bottom filling */
  mask-image:
    radial-gradient(circle at 0% 55%, transparent 5%, black 5%, black 33%, transparent 33%), /* Left hole */
    radial-gradient(circle at 100% 55%, transparent 5%, black 5%, black 33%, transparent 33%), /* Right hole */
    radial-gradient(circle at 50% 0%, transparent 7%, black 7%, black 40%, transparent 40%), /* Top hole */
    radial-gradient(circle at 50% 50%, black 0%, black 33%, transparent 33%), /* Middle filling */
    radial-gradient(circle at 50% 100%, black 0%, black 40%, transparent 40%); /* Bottom filling */
}

/* Anything below this is not required, just for fun */

html {
  background-image: url('https://picsum.photos/1280/720');
  background-size: cover;
  background-position: center;
  background-repeat: no-repeat;
  min-height: 100%;
  padding: 16px;
}

.ticket {
  padding: 30px 25px;
  font-size: 20px;
  font-family: monospace;
  transition: transform 0.2s;
}

.ticket:hover {
  transform: scale(1.05) rotate(4deg);
}

<div class="wrapper">
  <div class="ticket">
    I probably have a bit too much fun building this ticket-like element in pure
    CSS, enjoy!<br /><br /><a
