Elementor: How To Add Blur Effect With CSS Only — Blurred Background Popup Overlay

It’s good for Popups and other elements as well. Feel free to modify the blurriness to your taste.

Because backdrop filter blur effectis is heavy, don’t add motion effects on popup entrance, unless fade in and fade out (recommended duration is 0.3 s). 

If the performance on mobile is poor, disable the CSS for mobile. Use this code to disable.

					selector { backdrop-filter:blur(5px); }

					selector { backdrop-filter:blur(5px); -webkit-backdrop-filter:blur(5px); }
