How to use radial-gradient inside an -webkit-mask to make 3 transparent holes but keeping image

Question

I'm working on a project where I need to make a div that must have 3 random holes on the borders, making them transparent.

The issue I'm facing is, to 2 holes i'm using -webkit-mask with radial-gradient to create 2 transparent holes of 20px. My problem is when i'm trying to create a third hole, does anyone have any idea how to do this?

You can combine multiple radial-gradient to create more "holes" or effects, refer to this solution that I posted 2 days ago to create multiple "holes".

The next challenge will be the shadow, but will prefer using filter: drop-shadow with a wrapper component instead. box-shadow will not work with -webkit-mask / mask.

Here's an example of building the 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);
}

Hi @RicardoPagano, I have just modified my answer to include an example on what you can achieve on a ticket-like shape in pure CSS — AngYC, Apr 28 '23 at 19:02

Use the mask-composite property to create more complex masks:

Wow. i didn't know about mask-composite, i will try to take a look, but it's working too! thank you!!! — Ricardo Pagano, May 02 '23 at 18:18
@RicardoPagano, pay special attention to the fact that for different browsers, the values for this property are also different. For example, in Chrome, this property has more options, but they are missing in Firefox. — UModeL, May 02 '23 at 18:33
