How to do frosted glass effect with svg background?

Question

I'm trying to implement a frosted glass effect like the one seen here, over an svg background. I haven't had any luck so far, as while it works with bitmap images, with an svg background I just get a 100% transparent box.

I can't see why a blur filter would not be applied to an svg image and have not found answers when trying to search this.

This is my current attempt:

html,
body {
    min-height: 100vh;
    display: flex;
    flex-direction: column;
background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' version='1.1' xmlns:xlink='http://www.w3.org/1999/xlink' xmlns:svgjs='http://svgjs.com/svgjs' width='1440'

What do I need to do to make this frosted glass effect work with responsive svg backgrounds?

Answer 1

So I was able to achieve this by adding an empty div <div class="blurdiv"></div> into <div class="card frost-bg m-3"> as a child and adding this code to your CSS:

.blurdiv {
  position: absolute;
  display: flex;
  height: 100%;
  width: 100%;
  background: inherit;
  filter: blur(10px);
  opacity: 0.75;
}


.media-content {
  z-index: 1;
}

This basically expands that empty div to take up 100% of the width and height of the card which I would style in a "glass" form. Then I used z-index to pull your .media-content above the .blurdiv div making it the background.

See it working here:
