How to create a fading-out grind background

I want to create a grid background that fades out

So far I've tried a conic-gradient background but I'm not sure how to get it to fade out

  background:
    conic-gradient(from 90deg at 1px 1px,#0000 90deg,grey 0) 
    0 0/50px 50px;

The simplest solution would be add an additional background-image that has linear-gradient from transparent to white:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-css -->

body {
  background:
    linear-gradient(180deg, #FFF0 0%, #FFFF 100%) 0 0 / 100dvw 100dvh,
    conic-gradient(from 90deg at 1px 1px, #8880 90deg, #888F 0) center -1px / 50px 50px;
}

<!-- end snippet -->

or if you use some body height:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-css -->

* { margin:0; box-sizing: border-box; }

body {
  min-height: 100vh;
  background:
    linear-gradient(180deg, #FFF0 0%, #FFFF 100%),
    conic-gradient(from 90deg at 1px 1px, #8880 90deg, #888F 0) center -1px / 50px 50px;
}

<!-- end snippet -->

1. You can Use
   {
filter: blur(4px);
}
