backdrop-filter: blur();

I wish I had a ... hm-hm a property for contaiers that automatically applies backdrop-filter: blur() for container area.

This css property is finally supported by majority of browsers.
Bluring looks super cool and super fresh in UI design :)

Hi,

Quoted from "a.pu"

This css property is finally supported by majority of browsers.

Firefox doesn't support it by default yet (only when manually enabling the layout.css.backdrop-filter.enabled setting in about:config).

But it's possible to extend krpano to be able to it:

Source code

<style name="backdropblur"
       onloaded.addevent="register_backdropblur()"
       />

<action name="register_backdropblur" type="Javascript">
   var backdropblur = 0.0;
   caller.registerattribute("backdropblur", 0.0,
    function(v)
    {
      backdropblur = Number(v);
      if( isNaN(backdropblur) ) backdropblur = 0.0;
      var style = caller.sprite.style;
      style["backdrop-filter"] = style["-webkit-backdrop-filter"] = "blur(" + backdropblur + "px)";
    },
    function()
    {
      return backdropblur; 
    });
</action>

Usage example:

	Source code
1 2 3 4 5 6 7 8	<layer name="test" keep="true" style="backdropblur" type="container" align="center" width="50%" height="40%" bgcolor="0x123456" bgalpha="0.5" backdropblur="3" />
