Hello,
I’d like to know how to blur the background on the tablet/desktop mode when a screen Edit is opened from a button, displaying like a popup or a modal. I tried the CCS code shared by @Lucas_Pires @ThinhDinh on their Notion page to build a custom modal box but the result is not the one expected.
A screenshot will be more explicit 
Do you have any idea to blur only the background ?
Thanks for your help
Fabien
Can you specify which one are you using?
Sure. Here is it
/* Blurry */
<a style="top:180px;">
<div style="
position:fixed;
top:0px;
left:-5%;
margin: 0%;
padding:100vh;
background-color: rgb(0 0 0 / 70%);
backdrop-filter: blur(4px);">
</style></div></a>
I don’t think I have an answer for this. What we are trying to do here is putting a blurry background on top of what we are already have, I have tried using z-index specifically on that edit modal to put it on top of the background but it just doesn’t work.
